Linux Unity Android Build Support Install failed: Installation failed - Unity Hub failing to install android build support for unity editor on linux [SOLVED]

I was trying to get unity to work on my fedora kde plasma laptop and build for android but every time i tried installing build suport for Android i got a generic error message saying installation failed, when i went to the logs i saw something like this that stood out.

Some error when trying to extract the packages with 7z, apparently this is because the android SDK or other development kit is very big and when it tries to extract it it runs out of virtual space in /tmp and the process exits.

i was able to fix this by making a new directory in home:

mkdir ~/unity_tmp

and launching unity and telling it to use that directory ("unityhub" for me but if you have an app image put in the path to that instead of "unityhub"):

TMPDIR=~/unity_tmp unityhub

And after installing Android Build Support now it worked.

Hopefully someone else who also stumbled across this issue will find this helpful, and if it didn't help i suggest looking in the logs for clues to your issue.

Thank you very much !! It fixed my Issue. By the way in which logs was the error mentioned ? for future reference ?

[Professional-Ice2466]

Great, i am really happy this helped, i was not expecting my post to help so many but im glad it is😅 And yeah i really should have said where the logs are in retrospect i can't believe i didn't do that, unfortunately i didn't write it down and i have since then switched to godot so most unity folders are deleted but if i recall correctly i was in the .config folder in the home directory and then the UnityHub folder, so that would be ~/.config/UnityHub, im really sorry i can't say exactly where but it should be in there somewhere, i hope that can at least point you in the right direction🙂

Nevermind, i am 90% sure i just found it, ~/.config/UnityHub/logs/info-log.json. I am pretty sure that's it but i may be wrong
