Impossible to start Theia IDE on my Ubuntu 22.04 after a failed upgrade

[flzara]

Hi,

I had an old version of the Theia IDE installed through the AppImage on my Ubuntu 22.04. It proposed me to upgrade and I did so. However, it stalled/crashed during the internal update. So I shut it down, removed the previous AppImage file and downloaded the latest one (1.59), moved it to ~/bin, made it executable and started it via the terminal $ ./TheiaIDE.AppImage. I have no output. There is still something running in the background, but no window :

$ ps aux |grep theia
fzara     240254  0.0  0.2 1186878832 90568 pts/8 Sl+ 11:16   0:00 /tmp/.mount_TheiaIQXIU9K/theia-ide-electron-app.bin --no-sandbox

I removed every leftover I could find:

• in my home find ~ -type d -iname "*theia*"or find ~ -type f -iname "*theia*"
• in my /usr find /usr -iname "*theia*"
• files containing theia in dot directories grep -ri theia ~/.config ~/.cache ~/.local

Nothing left…and Theia is still not starting.

I created a brand-new user, copied the AppImage to its home/bin folder, made it executable, and… it works when using this brand-new test account!

What am I missing? Is there some leftover of the previous installation? A lock-file somewhere that I missed in my home folder?

Thank you for your help

Hey @flzara,

Does it also not work after a restart or when you kill all previous processes referencing Theia IDE. I think it will cause issues, when there are "leftover" processes open, because it will try to open a process for the old Theia IDE version. But with a completly new AppImage it should work if no leftover processes are there. Also could you try with preview version 1.60.1? Download Link

Hi @sgraband

Thank you for your help. I tried this morning with a cold start of my laptop and the preview version 1.60.1. Still no luck.

In another terminal, I can see that the process started

I don't know where to go from there
