Gain root shell on Termux.

tsu's Issues

CANNOT LINK EXECUTUBALE

Hi..I keep getting the below error everytime i try to use tsu to drop to root shell,i have su installed
CANNOT LINK EXECUTABLE "/data/data/com.termux/files/usr/bin/bash": cannot locate symbol "ucnv_open_56" referenced by "/system/lib/libmtk_symbols.so"...
Please help

need help that my phone's file was clean while try to use tsu

i try to use tsu but wipe all my file by accident,seens it not because of tsu but because of this termux/termux-app#735 (comment) ,so i close this issue.

Requires rooted?

Description of this doesn't state that it needs ROOT REQUIRED same if $ pkg search tsu

so it was put into the termux.com base repo vice in the root repo

tsudo removes quotes from commands

$ tsudo 'mkdir 'test1 test2''
$ ls -l
test1
test2

Correct output should be one directory with the name 'test1 test2', not two directories.

zsh shell isn't available in tsu mode in Termux

Latest updates caused an issue.
After gettin' in tsu mode the output of the commands looks like this:
echo $0
/data/.../com.termux/files/usr/bin/zsh

echo $SHELL
/system/bin/sh

The problem is that the zsh can't be used, so zsh history and syntax highlightin' are not available, although it worked in previous versions.

tsu command only works with root

tsu only works on root and is even worse when passed username
at least same username should result same result

I am trying to back to user of Termux from root. i have tried HOME=/data/...../home PATH=/data/...../sbin su u0_a194 -s /data/...../bash but doesn't seem to work properly

port 22 for ssh can not be used without root and when start sshd as root I login in root from ssh.

Falls on a loop if command is placed on bashrc

I added the 'tsu' command on the bash.bashrc file so whenever I start the app I get a root shell immediately. Though, once the app is started the terminal just constantly resets. I know it's supposed to reset once and that does happen when I start the app and TYPE OUT the command but placing the command on bashrc just throws the terminal in this infinite loop.

Cannot work with magisk

Magisk version is 12.6. Maybe 13.X is still not working.

Cannot link executable

Throws out the error below and terminates:

➜  ~ tsu
CANNOT LINK EXECUTABLE "/sbin/su": cannot locate symbol "u_foldCase_58" referenced by "/system/lib64/libsqlite.so"...
CANNOT LINK EXECUTABLE "/sbin/su": cannot locate symbol "u_foldCase_58" referenced by "/system/lib64/libsqlite.so"...

is this still maintained?

There are several pull requests (including one from me). @cswl is this project still maintained?

Tsu v8.0.0.a

https://github.com/cswl/tsu/releases/download/v8.0.0.a%2B/tsu_8.0.0a+_all.deb
I installed this version but when i try to call, termux returns; "The program tsu is not installed. Install it by executing: pkg install tsu"
And If I try pkg install tsu command,
It returns
"0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded."
I'm very confused about that.

An apt package with tsu is now available

I have now added tsu as an apt package, so after executing apt update to fetch the updated package list users can now install the script with

apt install tsu

and have it automatically update latest just as normal packages. You may want to update the README with this!

Ping me (perhaps by creating issue here and mention me, or by creating a pull request for updating https://github.com/termux/termux-packages/blob/master/packages/tsu/build.sh) whenever you have pushed something that you want to have packaged as an update of the apt package!

tsu doesn't work with aosp su

su binary built with aosp/caf doesn't have arguments and is very dumb.

Permission denied on Nougat

hi i have a samsung galaxy S7 edge (SM-G735f) rooted it using Magisk SU which is currently at V 1.18.1 I have troubles to execute commands some of them work (ex: echo) but others don't (like whoami and ls). When they don't i get this message:

bash: /data/data/com.termux/files/usr/bin/applets/ls: Permission denied

Help would be much appreciated

Magisk su issue

This issue will track fixes towards Magisk superuser which is mostly "Permission denied."
All remaining issues will be closed in favor of this one.

Permission denied

Having installed tsu, with tsu - A I get /data/data/com.termux/files/usr/bin/tsu: 139: exec: :Permission denied
Any help, please?

sudo not detecting superuser binary

Running anything using sudo shows:

No superuser binary detected.
Are you rooted?

Except su command is working properly.

Phone is rooted using SuperSU, which doesn't show up toast message when using sudo. Before update everything worked properly.

tsu permission denied issues on oreo

I originally posted this in #30 (comment):

I am experiencing issues on my Galaxy S7 since an upgrade to Oreo. Downgrading Magisk from 18.1 to a version that worked on Nougat (e.g. 16.3) doesn't help, so I doubt it is a Magisk issue at all.

tsu is able to launch a shell via magisk su but that shell isn't able to run any executable anymore.
Re-adding the LD_* variables doesn't help.
selinux is permissive.

I don't know if this is related to #33 because some users report that they are using SuperSU.
I've also had a look at branch v3.0-stash but it looks incomplete. (E.g. libtsu-magisk.sh is referenced but missing.)

Do you have an explanation for this behavior and is there a known workaround yet?

Here are some details:

tsu wrapper crashed with magisk 16.4

same issue as
termux/termux-app#672
which has been fixed

After tsu my pwd starts with (unreachable)

After running tsu my current working directory starts with (unreachable)...

[u0_a116` …/~]$ tsu
[root …/home]# pwd
(unreachable)/data/data/com.termux/files/home

I see that this has something to do with running env -i. If I take this out from the command it works fine.

[u0_a116 …/~]$ /sbin/su -c > 'PATH=/data/data/com.termux/files/usr/bin:/data/data/com.termux/files/usr/bin/applets:/system/bin:/system/xbin:/sbin:/sbin/bin ANDROID_DATA=/data TMPDIR=/data/data/com.termux/files/home/.suroot/.tmp PREFIX=/data/data/com.termux/files/usr TERM=xterm-256color LD_PRELOAD=/data/data/com.termux/files/usr/lib/libtermux-exec.so ANDROID_ROOT=/system HOME=/data/data/com.termux/files/home/.suroot /data/data/com.termux/files/usr/bin/bash'

tsudo always default at '/'

So in termux your user home is defaulted (least in my case) /data/data/com.termux/files/home/
so say when i try to do tsudo ./run.sh it will try to run it from /run.sh instead of /data/data/com.termux/files/home/run.sh
any way to change the default path on tsudo to where ever i run the command?

tsu in termux shows No superuser binary detected. Are you rooted?

I use latest version of magisk (87de0e7a(20408)) on my dell labtop with bliss os.
Tsu was not working. I am sure I have the correct binary su file in the right place.
Other app works fine on root permission requst.

Tsu is working but can't see anything I typed on.

Hello, I am really happy knowing about tsu, it worked though, however, on terminal, I can't seem to see words/strings i am typing into, but I am still getting response or results it's working, it's just I can't see anything I input on the terminal.

Help please!

After tsu, every command gives me Permission

Hi. Im trying to use aircrack-ng tools, but it seems I have a problem with permissions. Plz help. I'm using Galaxy S8, rooted, using Magisk 19.3 and already granted root permission to termux app. But when I tried to use the tool, I got this error.

$ airmon-ng check kill
Run it as root
$ tsu

airmon-ng

bash: /data/data/com.termux/files/usr/bin/airmon-ng: /data/data/com.termux/files/usr/bin/sh: bad interpreter: Permission denied

ls

bash: /data/data/com.termux/files/usr/bin/ls: Permission denied

All other commands give me Permission denied error. I just tried
$ tsudo airmon-ng ,
But it still gives me the same error. Someone please give me a solution

Tsu is not working with sh error

I using tsu formerly but i reinstalled termux and now it gives me a sh error. My input and output;

$ sudo su
/system/bin/sh: env: not found

I using last version of termux and termux api.
CPH1909(OPPO a5s)
Anroid 8.1.0

What I should do? Really I dont understand that..

ccsuper

Invalid option

After installing I wrote "tsu" and I have error:
enter main
/system/xbin/su: invalid option -- -

I think this error there section:

if [ -z "$USER_COMMAND" ]; then
exec "$SU_BINARY" --preserve-environment -c "LD_LIBRARY_PATH=$OLD_LIBRARY_PATH PATH=$PATH $ROOT_SHELL"
else
exec "$SU_BINARY" --preserve-environment -c "LD_LIBRARY_PATH=$OLD_LIBRARY_PATH PATH=$PATH $USER_COMMAND"

fi

Environmental variables are not set after issuing "tsu"

I have LineageOS 17.1 on Samsung Galaxy S4 LTE.

The latest update of tsu to version 8.5.1 broke my usual workflow.

Now, when I start tsu in Termux, I don't get my fancy command prompt ($PS1 is not set) but just one symbol "#". When I run "vim somefile.txt" inside of tsu, vim doesn't have any of the settings from my .vimrc file and .vim directory. Actually, all settings from my .bashrc are not used either, e.g. the variable $EDITOR is not set.

The variable $HOME inside of tsu is /data/data/com.termux/files/home/.suroot.

I don't know what more details to provide to make the description of the problem clearer. As far as I understand, tsu doesn't copy my environment and uses some default one.

Be a bit verbose when su is not present

Currently, tsu does nothing and silently exits when the phone is not rooted and there is no su binary. It would be nice to display a similar message like the dummy su shipped with termux-tools (maybe by invoking exactly this).

android-5 and android >= 7 branches

Hi,

The termux-packages repo is now using two branches, one for android 5&6 and a master branch for android >= 7.

Could you please create a new branch in this repo for android-5 & 6 (named for example android-5)?
We can then do android >=7 specific changes to the only the master branch and android 5&6 changes to the android-5 branch.

Termux for android >= 7 doesn't need LD_LIBRARY_PATH for example so that can be removed from the tsu script for android >= 7.

W: sandbox user '_apt' on the system, can not drop privileges

Getting W: sandbox user '_apt' on the system, can not drop privileges after execute some command under tsu mode

tsu is looking for su in the wrong place

I'm running LineageOS 14.1 on OnePlus3, tsu 8.2.0, termux 0.94. The device is rooted using the official LineageOS su package. tsu fails with:

/sbin/su: Permission denied

Because on my device the whole /sbin/ directory is inaccessible for non-root users. On the other hand, the su binary is present at /system/bin/su and just calling su successfully obtains root privileges.

/edit: the same issue occurs on LineageOS 16.0, Xiaomi Redmi 3s (land)

Getting issue with tsu

when i type tsu or sudo cmd it show me error /system/bin/sh :env nor found

tsu outputs this:

I've already opened a issue in termux packages.
termux/termux-packages#3917
Is this due to magisk update?
my magisk version is:
19.2(19200)
And magisk manager version is:
7.2.0(213)
And android version is
Android 8.1.0 Oreo

tsu .bashrc

There was a small problem with customizing .bashrc ... In normal user mode it works, but when I go to superuser mode it doesn't want to work.

Changes..:
sudo -u USER and tsu USER works now
sudo now includes -E option to preserve environment variables
/system and /sbin PATHS are now included by default in recent Termux install without LD_LIBRARY_PATH

Touchscreen and key combinations not working in aps running with tsu

It just send keycodes to screen in apps lilke mc or htop
no mater if i try touch F10 or press Volume Up+0

Strange error whenever I try to run tsu

I get the following output on invoking tsu:
/system/bin/sh: no closing quote

Any idea where to look? I reinstalled but no luck.

tsu and tsudo: "permission denied."

I'am using Supersu and i have problem with tsu and tsudo. Every time I use tsu or tsudo with any command I get the "permission denied" error. A few weeks ago everything was fine. How can I solve? Thanks and sorry for my english.

no binary found

running tsu give the output

"No superuser binary detected. \n"
"Are you rooted?

I can confirm that su is in /sbin/ folder
Using magisk 14.3

Cannot change to another user

So, in the show usage, I see that we have [USER] argument. So I think I use that to change another user other than "root".

$ tsu u0_a78
# whoami
root

well it's not. Alright, so I try with sudo. I see that we have -u [user] argument. So............ nope.

$ sudo --dbg -u u0_a78 bash                                                                                                                                             + shift

kinda funny it's written on help but.... not implemented? 😨

Is there's something wrong? Or I misunderstood something? Is this because I use old Magisk? I rarely update it because it needs to be updated via recovery, or else I lost my root.

Sudo permission

What is problem

ANDROIDSYSTEM_PATHS does not include '/sbin' path

Shouldn't ANDROIDSYSTEM_PATHS includes /sbin as part of the system paths added with options -p and -a ?
I have installed the Magisk module acc and its executable was added to the folder /sbin. I was hoping to access acc from the PATH.
Maybe there are some reasons for not adding /sbin so this issue is more like a question/request.
