apt dist-upgrade uninstalls quassel-client

[Heinrich Schuchardt]

Trying to run dist-upgrade asks for uninstalling quassel-client on amd64. This is related to some unfullfillable dependencies:

The following packages have unmet dependencies:
 quassel-client : Depends: libqt5core5t64 (>= 5.15.1) but it is not installable
                  Depends: libqt5dbus5t64 (>= 5.14.1) but it is not installable
                  Depends: libqt5gui5t64 (>= 5.14.1) but it is not installable or
                           libqt5gui5-gles (>= 5.14.1) but it is not installed
                  Depends: libqt5network5t64 (>= 5.15.1) but it is not installable
                  Depends: libqt5widgets5t64 (>= 5.14.1) but it is not installable

Could it be that something is wrong with Qt's t64 packages? Shouldn't they replace the non-t64 ones?

Hi Heinrich!

The noble archive for amd64 is currently in a semi-broken state. As an attempt to mitigate the consequences of CVE-2024-3094, all amd64 binaries built with compromised xz-utils were removed from the archive, which rendered some packages uninstallable.

If you want a stable archive, try using noble-updates only (without the release pocket). It contains an older, pre-CVE-2024-3094 snapshot. Or wait until things settle down and packages become installable in noble again.

Also, installing the packages using "dpkg -i" may break your system, as that command does not check the dependencies. Use "apt install ./*.deb" instead, which is safer.
