do-client download fails

do-client download fails

[jimson-msft]

@Voxel07 Thanks for the feedback, mind sharing the full do agent logs - or are those two lines of text the only ones appearing? The json file not being present is not a fatal error, the logging should just reflect that the file isn't there - but this shouldn't block your download. Having more logging would help.

From the adu-agent logging, that specific error code bubbling from DO is maps to E_INVALIDARG, this usually signals something wrong with the filepath or the download url. The url looks okay, so I suspect perhaps DO may not have permissions to download to that directory.

Is the DU agent running as DU user? Is DO running as DO user?
You can also try verify the file permissions of the download sandbox in /tmp/ - or feel free to share them here.
You can verify file permissions by trying to catch the sandbox when it's created and before adu agent removes it and running
'ls -l' in the /tmp/ directory.

I will post the whole log on Monday, but I think the rights might be the issue, because when I check with ls -l everything was root.

@jimson-msft The whole log:
please note that the IoT Hub Url changed because I had to change subscriptions.

@Voxel07, how strange - it looks like the caller of the download_url_to_path() api is supplying an empty url, and it looks like the download path is getting supplied with respective download url.

Taking a look at logging line here:

2021-04-23T13:44:32.5969194Z 787 868 info {Download} de5d13bf-8cca-9d49-be24-10424938a42b, new download, url: , dest: http://iot-hub-update-instance-schneider--device-update-schneider.b.nlu.dl.adu.microsoft.com/northeurope/IoT-Hub-Update-Instance-Schneider--device-update-schneider/8761c4bc9566483a94ef012d0426f9b2/workingUpdate

Notice the empty url, and the presumed download url getting supplied as the download file destination.

Did you happen to modify the source for either client?
@Nox-MSFT as an FYI

[Voxel07]

@jimson-msft, I compared the files with meld and could not find a relevant change. So reverted all changes and no that made no difference. To be a 100% sure I downloaded the newest releases from git (changed from 0.6.0 to 0.7.0) and ran the whole setup again. And the log changed. Now the url and dest contain the correct paths. Out of Curiosity I installed the agent with my changes and the the missing url error is gone as well. I think I had changes in the background which were overwritten by the install-deps script.

Unfortunately the E _INVALIDARG Error is still present.

Thanks @Voxel07, In this case - the E_INVALIDARG may be the result of the DU and DO user/groups not being set up. The error specifically looks like DO does not have permissions to download to the destination path (the DU sandbox).

DU agent runs as DU user and DO runs as DO user - in our binary distributions (debian packages) - the debian control scripts handle provisioning this. If you're building from source, its possible that the DU and DO user/group is not being setup correctly. I believe I've seen this issue a couple times on the DU github issues as well - so this is great feedback for our teams to make the the provisioning of the user/group more clear.

Consider reviewing our control scripts (they're just shell scripts) to find the relevant code to setup the DO/DU users directly.
The DO control script which handles post-install and setup of the user/group can be run from here:
https://github.com/microsoft/do-client/blob/main/client-lite/build/postinst.in.sh

The DU control script which handles post-install and setup of the user/group can be run from here:
https://github.com/Azure/iot-hub-device-update/blob/main/packages/debian/postinst

@jimson-msft I already looked into the src code to find out how it should be and wrote my own setup script. But I will take another look into this tomorrow.
@ValOlson mentioned how to set it up until the documentation is updated.
I am running the Agent with this command:

matthias@matthias-VirtualBox:~/Desktop/azure/do-client$ sudo -H -u adu bash -c AducIotAgent

And when looking at the process with "top" I can see that DU is running as du and DO as do. The only thing remaining thing is the do agent exe in /usr/local/bin

voxel@ubuntu:/usr/local/bin$ ll
total 14992
drwxr-xr-x  2 root root     4096 Apr 19 10:23 ./
drwxr-xr-x 10 root root     4096 Aug  6  2020 ../
-rwxr-xr-x  1 root root 15341520 Apr 19 10:11 deliveryoptimization-agent*

should this be

drwxr-xr-x 10 root root  4096 Aug  6  2020 ../

Here are the updated instructions on how to create 'adu' user and group that includes the DO agent.

[Voxel07]

@ValOlson @jimson-msft Thank you very much for helping with this.

• I deleted the agent in /usr/lib. The install_prefix mentioned in build.sh is also /usr/local.

If my research is correct, then this is the folder for programs installed with a package manager. And when compiling software with cmake,... it should be placed in /user/local/lib. Pls correct me if I am wrong, because the build.sh with the --install option puts it into /usr/lib/adu.

• Then I changed the permissions of the agent in /local/lib according to the new instructions. To me everything looks the same, but the download is now successful.
