From 3.4.10 already significant pacman key issue existing, forcing us to skip signature verification for many of the packages. Now 3.5.5 makes the situation more frustrating.
- linux-neptune-61-headers still not being migrating from jupiter-main to -rel
- virtualbox-host-dkms build requires libguile-2.2.so.1 while the installed Guile is already 3.0.7
- base-devel even forcing downgrade for most of the packages, corrupting sudo
Well Steam OS is not designed for usage besides gaming so it is nothing to be complained here, but if you rely on pacman heavily like me, better to skip this version and wait for improvement.
Note: to rollback, use Option + Power to select previous OS, then run command ‘sudo rauc status mark-active booted’ as this post.
i was having key issues, but i deleted the cache and re-initialized. no errors after.
