Thanks Liza,

it worked and it is very nice.

I got the impression that I had to instruct Ubuntu to pick the TeXmacs 
repository version instead of the Ubuntu repository version, as it was 
considering the 2.1.4 in the Ubuntu repo as newer, so I did it by asking 
an LLM.

I am not confident though, that all steps I did were logical and that it 
could not have worked in a simpler way. But maybe this is an issue to 
consider as well.
