Flatpak Id Migration Pains

[PhoneDroid]

OS/Platform

Debian, Ubuntu, and derivatives

Installed

Flatpak

Version

Version 125.0.6422.76 (Official Build, ungoogled-chromium) (64-bit)

Have you tested that this is not an upstream issue or an issue with your configuration?

• I have tried reproducing this issue in Chrome and it could not be reproduced there
• I have tried reproducing this issue in vanilla Chromium and it could not be reproduced there
• I have tried reproducing this issue in ungoogled-chromium with a new and empty profile using --user-data-dir command line argument and it could not be reproduced there

Description

Without giving UG access to all system files it doesn't start after the Flatpak migration

How to Reproduce?

1. Install UG via Flatpak
2. Attempt to run either via application shortcut or its resulting command

   /usr/bin/flatpak run --branch=stable --arch=x86_64 --command=/app/bin/chromium --file-forwarding io.github.ungoogled_software.ungoogled_chromium @@u %U @@
   

Actual behaviour

UG doesn't start and prints the below log.

Expected behaviour

It starts.

Relevant log output

Check failed: false. NOTREACHED log messages are omitted in official builds. Sorry!

Additional context

• I upgraded my system ( Kubuntu ) to 24.04 ( Noble Numbat ) this week

• I got the Flatpak Id migration notice

• I migrated UG

• UG didn't open anymore

• I tried running the application shortcut command manually
  ⭢ Resulted in the log
  ⭢ No useful info

• Checked around for any issues, discussions, gitter talk, ..
  ⭢ Nothing

• Found the portable version ( Appimage )
  ⭢ Works but didn't use my current profiles

• Attempted to use Flatseal to give it all permissions
  ⭢ Didn't work
  ⭢ Apparently I had to close Flatseal every time to have the settings apply
  ( Nope, I was just too fast and it didn't adapt the change right away )

• Attempted to use Flatseal to give it all permissions & closing it
  ⭢ Worked!

• Narrowed down the required permissions to be changed to:

@PhoneDroid I can't reproduce it, what are the contents of ~/.local/share/flatpak/overrides/io.github.ungoogled_software.ungoogled_chromium?

[rany2]

Can you try running flatpak update again? Apparently there's some issue in Freedesktop SDK and I'm not really sure if it's just unfortunate timing or not.

[PhoneDroid]

~/.local/share/flatpak/overrides/io.github.ungoogled_software.ungoogled_chromium

It's empty if I don't patch it with flatseal

And contains the following with the setting changed:

[Context]
filesystems=host

It did update something I guess:

But wasn't fixed by it.

[rany2]

I'm not facing this issue and I don't really know what's wrong atm, but what I could tell you is that the two packages were exactly identical so it's not clear to me what is causing this problem. If there are any more logs you could get, info, etc it might help.

Well, what is the output of ls -lah ~/.var/app?

[PhoneDroid]

Well like I said, the log isn't saying anything:

Well, what is the output of ls -lah ~/.var/app?

Maybe it's because I have my chrome profiles in a custom? location?
/media/<User>/<Drive>/Settings/Chrome_Profiles/Data
( Have them in a local git repo )

[rany2]

Maybe it's because I have my chrome profiles in a custom? location?
/media/<User>/<Drive>/Settings/Chrome_Profiles/Data
( Have them in a local git repo )

Might be worth exempting that as well and dropping the --filesystem=host?

Seems to work, thanks!

Should this be documented somewhere like the FAQ, something like Custom Chrome Profile Location?

[rany2]

The old app ID would have required the same thing, most likely you forgot you put that exemption?

I don't remember ever using Flatseal to patch it ..

[rany2]

@networkException Can you pin this issue and change the title a bit to clarify what the issue is? I doubt it's a common setup but just in case....

@PhoneDroid well, it had to have been the case.. maybe you used flatpak override instead of Flatseal? They both do the same thing

[PhoneDroid]

Only ever used Flatseal for 2-3 other programs, haven't touched the cmd-line - as far as I can remember.

Should I close the issue?
