Hello,

didier@hp-notebook14:~$ apt-file search libgallium # (trixie+backports 
repositories here):
mesa-libgallium: /usr/lib/x86_64-linux-gnu/libgallium-25.0.7-2+deb13u1.so
mesa-libgallium: /usr/lib/x86_64-linux-gnu/libgallium-25.0.7-2.so
mesa-libgallium: /usr/lib/x86_64-linux-gnu/libgallium-25.2.6-1~bpo13+1.so
[...]

I would suggest to investigate your apt sources because 
libgallium-26.1.2-1.so on your system does not seem to be present in 
trixie+backports repos...

apt-policy mesa-libgallium should indicate where this package come from:

didier@hp-notebook14:~$ LANG=en-US.UTF-8; apt policy mesa-libgallium
