Bug#1123931: libegl-mesa0: Multi-arch install of mesa broken in testing due to impossible constraints
Package: libegl-mesa0
Version: 25.2.8-2+b3
Severity: important
Dear Maintainer,
trying to install/upgrade any mesa package in "testing" right now fails
completely when using amd64 + any other arch (eg. amd64 + i386) due to
impossible to satisfy constraints between the package versions (amd64 has a -b3
version and constrains i386 to it, while i386 only has a -b2 version).
Shell output (explicitly specifying the package versions to get more debug
info):
$ apt install libegl-mesa0:i386/testing libgbm1:i386/testing mesa-
libgallium:i386/testing libgl1-mesa-dri:i386/testing libglx-mesa0:i386/testing
