Package: libfst-dev Version: 1.7.9-5 Severity: serious While testing upgrades from bookworm to trixie, I ran into the following problem. If I: - install libfst-dev in bookworm - upgrade to trixie (apt update && apt dist-upgrade) Then libfst-dev is not upgraded.
MWE: mmdebstrap --chrooted-customize-hook='apt -y install libfst-dev && sed -e s/bookworm/trixie/ -i /etc/apt/sources.list && apt update && apt dist-upgrade -y && apt dist-upgrade -y -o Debug::pkgProblemResolver=true' bookworm /dev/null Relevant output: Investigating (0) libfst-dev:amd64 < 1.7.9-5 -> 1.8.4-2 @ii umU Ib > Broken libfst-dev:amd64 Depends on libfst26:amd64 < none | 1.8.4-2 @un uH > (= 1.8.4-2) Considering libfst26:amd64 0 as a solution to libfst-dev:amd64 0 Holding Back libfst-dev:amd64 rather than change libfst26:amd64 Try to Re-Instate (1) libfst-dev:amd64 Done Entering ResolveByKeep The following packages were automatically installed and are no longer required: libapt-pkg6.0 libargon2-1 libgnutls30 libtasn1-6 libunistring2 Use 'apt autoremove' to remove them. Not upgrading: libfst-dev What happens is that libfst22 and libfst26 cannot be co-installed, because libfst22 Conflicts with libfst, which is Provided by libfst26. I'm not sure of how to untangle this. This affects upgrades of the following packages: hfst libfst-dev libfst-tools libhfst-dev libhfst55 python3-hfst python3-libhfst Lucas
