All hyperlinks provided by Ubiquity are opened with gedit

journalctl entry. Nothing too fancy, just confirming that it is indeed opened with gedit.

Launchpad won't let me add another attachment but here is the strace output: https://pastebin.ubuntu.com/p/JVFybhDvhb/

Reproduced with 20210930 image - Boot live session, start ubiquity, click on release notes link.

This bug has been reported on the Ubuntu ISO testing tracker.

This happens because of sanitized environment in the ubiquity.desktop file.

ubuntu@ubuntu:~$ grep ^Exec= /usr/share/applications/ubiquity.desktop
Exec=sudo --preserve-env=DBUS_SESSION_BUS_ADDRESS,XDG_RUNTIME_DIR sh -c 'ubiquity gtk_ui'

Please add the $XDG_DATA_DIRS environment variable into the whitelist to fix the issue. You can find among autotests a complete list of environment variables that may affect xdg-utils.

Nice find! That is indeed the case.

Running ubiquity through shell with $XDG_DATA_DIRS included fixes it.

I reckon these are the files to be modified:

/ubiquity/gsettings.py
/data/ubiquity.desktop.in

Very nice catch Nicholas! I can confirm that modifying the ubiquity desktop file in a live session to add XDG_DATA_DIRS to the list of preserved environment variables fixes the bug indeed.

Awesome! Great work!

This bug was fixed in the package ubiquity - 21.10.8

ubiquity (21.10.8) impish; urgency=medium

The latest daily ISO as of today (2021-10-07) appears to still have ubiquity 21.10.6, but if I launch a live session and upgrade ubiquity to 21.10.8, then I can confirm that the problem is fixed.

It's not fixed on my side, though `apt-cache policy` shows that 21.10.8 is available and was successfully installed.

Is running `apt install ubiquity` enough?

Thanks!

I forgot to mention, in a live session the desktop file on the desktop isn't a symlink to the one installed by ubiquity, so it also needs manual editing to replicate the changes to the Exec line.

I'll respin the desktop images, the amd64 one seemed to have failed to build. We should have a new one soon.

Verified fixed in the 20211008.1 daily live ISO.

I can also confirm that the bug is fixed in Ubuntu Desktop amd64 20211008.1 daily build.

Just in case. :)
