You can safely ignore those lines.

What you noticed there aren’t "errors". Instead, you’re looking at "warnings" (which you can recognize from the fact that those lines are prepended with a w).

The reason you’re seeing those warnings (and what they don’t tell you) is that all AMD graphics will now load up with llvmpipe and spit out that message (especially in development version).

Anyway, those warnings can be safely ignored.

Nota Bene: What you do not want to do is to fetch the files apt warns about from sources like people.freedesktop.org/~agd5f/radeon_ucode/raven/ as that might introduce a potential attack vector. If you embrace your personal security, don’t simply trust unknown binaries from random sources which can not be verified to be benign.

I'll tell you how to quiet the warnings!

Put the names of the "missing" files with full paths in a temp file. I called my temp file 'myraven'.

Give the command:

sudo touch $( cat myraven )

Done. (You can remove the temp file, of course.)
