Hi, before I contiue to complain about some annyoances. Some things that can't be taken for granted are good OOTB. For example, on Arch Linux the reported scaling_max_freq is 5800000. This isn't correct for the CPU in my machine, see https://www.intel.com/content/www/us/en/products/docs/processors/core/13th-gen-core-desktop-brief.html , while 4500000 as reported by the default Xubuntu install is correct. For the Xubuntu install I might lower the base_frequency to 3400000, but maybe this doesn't matter at all.

The package "shim-signed" was not removed by an update that I run manually, it was removed without a warning by the automated update. Fortunately booting still works without it. With grub and kernel packages hold still "friendly-recovery" auto- generated a new, but broken grub.cfg. Why does this happen? Neither grub nor a kernel was updated. root@xubu:~# apt update && apt full-upgrade; apt autoremove [...] Setting up friendly-recovery (0.2.41ubuntu0.20.04.1) ...
