Description Denis Bitouzé 2021-01-27 16:18:00 CET 
Description of problem:
meld fails to start due to:

$ meld
Traceback (most recent call last):
  File "/usr/bin/meld", line 368, in <module>
    import meld.meldapp
  File "/usr/lib/python3.7/site-packages/meld/meldapp.py", line 29, in <module>
    import meld.ui.util
  File "/usr/lib/python3.7/site-packages/meld/ui/util.py", line 20, in <module>
    from meld.ui import gladesupport  # noqa: F401
  File "/usr/lib/python3.7/site-packages/meld/ui/gladesupport.py", line 7, in <module>
    from meld import diffmap  # noqa: F401
  File "/usr/lib/python3.7/site-packages/meld/diffmap.py", line 19, in <module>
    import cairo
ModuleNotFoundError: No module named 'cairo'

How reproducible:
Just start meld.

A common reason to this error is that lib64cairo* are missing, but they are installed on my box:

# urpmi lib64cairo-devel lib64cairo2
Les paquetages lib64cairo2-1.16.0-2.2.mga7.x86_64, lib64cairo-devel-1.16.0-2.2.mga7.x86_64 sont déjà installés

Install python3-cairo.
Comment 2 Jani Välimaa 2021-01-28 17:52:51 CET

> Install python3-cairo.

Or better, test meld-3.20.1-1.1.mga7 from core/updates_testing.

Already installed.

I enabled this source but only meld-3.20.1-1.mga7 is proposed.

Thanks!

$ rpm -q -i meld|grep -e ^I -e ^So
Install Date: 2019-10-26T17:23:14 EDT
Source RPM  : meld-3.20.1-1.mga7.src.rpm

This was installed from the core updates testing repo on the princeton
mirror.

Quick testing shows it works.

Advisory committed to svn. Validating the update.

Once the update gets pushed, it will be available in the core updates repo,
instead of the core updates testing repository.

Removing the ok.
meld-3.20.1-1.1.mga7 Just showed up in updates testing with a failed (missing)
signature.

Guess I jumped the gun testing meld-3.20.1-1.mga7 and must have already had
python3-cairo installed.

Will follow up with sysadmins about the missing signature on the package.

In fact, I'm not sure. Indeed, I'm currently on another computer, with un up to date Mageia 7 as well. And, on it, meld works like a charm :$

Hou.
