GUI not starting

[Bira-oliverio]

I'm using Fedora 36 and Gnome 42.1, when I try to run rmlint with gui interface I receive the following message.

$ rmlint --gui Traceback (most recent call last): File "/tmp/.shredder-bootstrap.py.4QU8M1", line 18, in File "/usr/lib/python3.10/site-packages/shredder/init.py", line 11, in gi.require_version('GtkSource', '3.0') File "/usr/lib64/python3.10/site-packages/gi/init.py", line 129, in require_version raise ValueError('Namespace %s not available for version %s' % ValueError: Namespace GtkSource not available for version 3.0

Thanks.

How did you install rmlint? The GUI needs gtksourceview3 (it's looking for /usr/lib/girepository-1.0/GtkSource-3.0.typelib), but it seems like you don't have it installed.

After installing gtksourceview3 I got a similar error.

$ rmlint --gui

ValueError: Namespace GtkSource not available for version 3.0

As you can see GtkSource-3.0.typelib is in the right place

$ ls /usr/lib/girepository-1.0/GtkSource-3.0.typelib -l
-rw-r--r--. 1 root root 72120 jan 20 09:14 /usr/lib/girepository-1.0/GtkSource-3.0.typelib

It seems like it finds some version of GtkSourceView, but not the right one. What does the output of these commands look like on your system? My results are provided for comparison.

Here you have the results, you are right the system is not finding the GtkSource-3.0.typelib, but I don't know how to fix this.

[cebtenzzre]

It seemed like that might be the issue, but I wasn't sure until now - /usr/lib64 and /usr/lib are different directories on Fedora, and GtkSource-3.0.typelib is installed in /usr/lib/girepository-1.0. Unless you've ended up with a 32-bit version of gtksourceview3 (dnf info gtksourceview3 | grep Arch ?), I assume the solution is as simple as setting GI_TYPELIB_PATH=/usr/lib/girepository-1.0 (or possibly GI_TYPELIB_PATH=/usr/lib64/girepository-1.0:/usr/lib/girepository-1.0) so that gi can find the typelib.

[Bira-oliverio]

Yes, you are right, I removed the previous gtksourceview3 and intelled the right architecture version and everything worked. Thanks..

[cebtenzzre]

I messaged the maintainer of the Fedora package about this. I'll post an update if I get a response. For now, you can close this issue since it's not an upstream problem.
