Installation procedure not working for Ubuntu 20.04 LTS

[babluboy]

Try and install ninja with the following commands:
sudo apt-get update -y
sudo apt-get install -y ninja-build

[MWNautilus]

I tried it and the ninja paket gets installed, but the bookworm installation still fails afterwards with the same error message saying that ninja is missing.

For me it's happening the same @babluboy.
Even after installing ninja with your instructions:
This is the shell output:
The following packages have unmet dependencies:
com.github.babluboy.bookworm : Depends: ninja but it is not installable
E: Unable to correct problems, you have held broken packages.

[babluboy]

can you also try and install ninja:
sudo apt-get install ninja

Can it be related to this issue:
mesonbuild/meson#6867

As per that issue, it will be great if you can try and install ninja using pip3:
python3 -m pip install ninja

Hi @babluboy! I've also tried everything and get the same errors as @MWNautilus & @AdrianoHeller. Went through all the steps you suggest and while I already have the newest version of ninja when I try to install it using pip3 I get this /usr/bin/python3: No module named pip
I am incapable of doing anything other than copy pasting as I am clueless re Linux so it could very well be that I am missing sth. My OS install is fresh (as of this afternoon).

Please, is there anything else you think we could try (I tried all the methods except for building it from source)? atm I'm stuck w/ Readium and it just ain't as cute as yours!

Wishing you a good day!

Nevermind, it worked after restarting I think it was the flatpack install that did the trick!

[babluboy]

Until I install Ubuntu 20.04 and try this out myself, consider using bookworm with flatpak:
flatpak install --from https://flathub.org/repo/appstream/com.github.babluboy.bookworm.flatpakref

This is a workaround and not a solution - so keeping this issue open

Package ninja is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'ninja' has no installation candidate

As per that issue, it will be great if you can try and install ninja using pip3:
python3 -m pip install ninja

I have python and pip installed so it will work for me.

But this will install ninja, but not as system package therefore install still fails even if ninja is now present on the system

mateusz@grima:~$  python3 -m pip install ninja

flatpak install --from https://flathub.org/repo/appstream/com.github.babluboy.bookworm.flatpakref

How I am supposed to run it after an install?

EDIT: flatpak run com.github.babluboy.bookworm

BTW, #325 is the same issue.
