I have upgraded to 20.09 on Friday and just noticed that
thunderbird are now compiling locally, which seems to take forever and causes my CPU to be fully utilised for a long time.
I thought that these packages were downloaded from a cache server before. How come that some packages compile locally and others are available for download from a cache server?
(I solved the issue for Thunderbird by switching to
thunderbird-bin, but a similar package doesn’t seem to exist for LibreOffice, or doe sit?)
