After updating to 22.04 recently, this command has stopped working:

git difftool --tool=meld -y HEAD~1

Viewing (1/15): 'file.txt'
Launch 'meld' [Y/n]? y
Trace/breakpoint trap (core dumped)
fatal: external diff died, stopping at file.txt

I've already tried both reinstalling meld with --reinstall as well as removing it with --purge and --auto-remove and installing again. No use.

I've also tried to launch meld from the console, but it's breaking as well:

meld ./file1.txt ./file2.txt

Trace/breakpoint trap (core dumped)

Weirdly enough, it seems to be launching fine from the GUI, but that's not what I need. I need to use it with git difftool.

Is this because of Wayland? Any way I could debug this?

EDIT:

Additional info: meld installed through apt, version 3.20.4-2.

I've also filed a bug on Launchpad, just in case: https://bugs.launchpad.net/ubuntu/+source/meld/+bug/1994970.

  • How are you installing meld? [from here](https://flathub.org/apps/details/org.gnome.meld)? – Robert Longson Oct 27 '22 at 12:32
  • @RobertLongson, no, I'm using `apt` and the default Jammy repositories. – Ainar-G Oct 27 '22 at 12:41
  • you could also try installing from source: `git clone https://git.gnome.org/browse/meld ; cd meld ; sudo python setup.py install` – Robert Longson Oct 27 '22 at 12:46
  • @RobertLongson, if all else fails, I may try flatpak or installing from source, but for now I would like to avoid that, if that is possible. – Ainar-G Oct 27 '22 at 12:59
  • I'm having [the same issue with Beyond Compare](https://forum.scootersoftware.com/forum/beyond-compare-4-discussion/linux-aa/88824-bc4-as-a-git-merge-tool-says-fatal-external-diff-died), on Fedora, though. – sschuberth Jan 09 '23 at 14:19
