It looks like apt wasn't wanting to install various t64 packages with apt upgrade.
After forcing upgrades of some larger packages like evolution or llvm with apt install <packages> and seeing the pattern of install removing a library and replacing it with a t64 version. Upgrading: evolution gir1.2-camel-1.2 evolution-common gir1.2-ebookcontacts-1.2 evolution-data-server gir1.2-edataserver-1.2 evolution-ews libcamel-1.2-64t64 evolution-plugin-bogofilter libedataserver-1.2-27t64 evolution-plugin-pstimport libedataserverui-1.2-4t64 evolution-plugins libevolution Installing dependencies: libmspack0t64 REMOVING: libmspack0 I decided to force trying to install libgtk-4-1 and this is what it wasn't willing to install on an apt upgrade, the relevant section of the plan is here: Upgrading: gir1.2-gtk-4.0 libgtk-4-1 libgtk-4-bin libgtk-4-common libgtk-4-media-gstreamer Installing dependencies: libcpdb-frontend2t64 libcpdb2t64 Summary: Upgrading: 5, Installing: 2, Removing: 0, Not Upgrading: 208 Download size: 9,084 kB Space needed: 16.4 MB / 793 GB available Hope that helps.
