Stuck at "processing triggers for mailcap"

[Solstar]

followed the guide (I have been doing vm installation for years so not the first time) and copied/pastyed the command on the github readme, but instead of ending like it should (or as seen on yt videos) it ends with "processing triggers for mailcap" and nothign else is done. Don't know if it's right or worng, if i have to shutdown or do the process again
