Well, I had enough of waiting for PureOS 11 “Crimson”, so I just upgraded to Debian12 “Bookworm” on my Librem 15v4. There is only so much you can keep up with, even with Debian bullseye-backports added to your PureOS apt repo list.
Full backup, a fresh install, and restore.
There are some nice automagic features in there, such as Bluetooth being available immediately (instead of the need to manually add it in via adding the Debian apt repo non-free, which has been discussed on this forum before). Of course, I understand the reasoning for that, so this is not a criticism of that stance, simply an observation.
When I run vrms on the new installation, I find only 4 non-free packages:
firmware-atheros;
firmware-misc-nonfree;
firmware-sof-signed; and
intel-microcode .
And, of course, if you want libreoffice to be passably interoperable with the rest of the Microsoft universe, then there is also a need to add the contrib package:
ttf-mscorefonts-installer.
So, not a totally ideal “pure” installation, such as the philosophy behind PureOS, but very close to the spirit of it. As the quote from Carl Schurz has it:
Our ideals are like the stars; we may never reach them, but we chart our courses by them.
It is clear exactly how much this installation deviates from the ideal.
The new install is very snappy on the Librem 15, which is still happily chugging along even after 4 years.
