Hi Jan,

Taking a screenshot using hotkey does not work.
When taking a screenshot from the command line, one gets the following
error message:

   spectacle: error while loading shared libraries: liblapack.so.3: cannot 
open shared object file: No such file or directory

Creating a softlink for liblapack.so.3 in /usr/lib/x86_64-linux-gnu
fixes this issue.
The next error encountered then is:

   spectacle: error while loading shared libraries: libblas.so.3: cannot 
open shared object file: No such file or directory

Creating a softlink for libblas.so.3 in /usr/lib/x86_64-linux-gnu fixes
this issue. Taking screenshots with the KDE hotkey then works.

Those two should point to  /etc/alternatives/ by default. Did you maybe 
manually change the alternative in the past?
Can you send the output of:

update-alternatives --display liblapack.so.3-x86_64-linux-gnu
update-alternatives --display libblas.so.3-x86_64-linux-gnu

Thanks!

Hi, sorry if it is somehow my fault.
Note that I updated from Debian 12 and it is not a fresh install.
Here is the output of update-alternatives:
