I am trying to install amdgpu-lib which has many dependencies from testing and possibly unstable. Not wanting to turn my entire system unstable, I created /etc/apt/preferences as follows:
Package: * Pin: release a=stable Pin-Priority: 700 Package: * Pin: release a=testing Pin-Priority: 650 Package: * Pin: release a=unstable Pin-Priority: 600 The pinning in /etc/apt/preferences prefers stable over testing over unstable, which are also available. Looking at libc6...
apt-cache policy libc6 outputs
libc6: Installed: 2.31-13+deb11u6 Candidate: 2.31-13+deb11u6 Version table: 2.36-9 650 650 http://deb.debian.org/debian testing/main amd64 Packages 600 http://deb.debian.org/debian unstable/main amd64 Packages *** 2.31-13+deb11u6 700 700 http://deb.debian.org/debian stable/main amd64 Packages 100 /var/lib/dpkg/status 2.31-13+deb11u5 500 500 http://deb.debian.org/debian stable-updates/main amd64 Package which states that libc6 version 2.36-9 is available from testing, even if not preferred.
apt-get install amdgpu-lib reveals many dependency errors:
... The following packages have unmet dependencies: libdrm2-amdgpu : Depends: libc6 (>= 2.33) but 2.31-13+deb11u6 is to be installed ... Meeting this requirement needs to install libc6 from testing. This may release a tree of upgrades from testing, but the resolution should exist and the result would be an OS that contains as little from testing and/or unstable as possible.
There are many dependency errors like this. Can apt handle this automatically?
