Just upgraded this morning (Kaos_next) - afterwards am unable to launch libreoffice.
linux 5.15.6-1-next #1 SMP PREEMPT Wed Dec 1 12:34:53 UTC 2021 x86_64 GNU/Linux
From CLI -
/usr/lib/libreoffice/program/soffice.bin: error while loading shared libraries: libicuuc.so.69: cannot open shared object file: No such file or directory
/usr/lib contains two libicuuc files - a link libicuuc.so.70 and an executable libicuuc.so.70.1
So I guess that the soffice.bin is looking for the wrong version..
How to fix,
