39.4 Yoga Maintenance

20210615 Yoga is a Lenovo ThinkPad X1 Yoga 4th Gen. See Section 39.2 for details.

Upgrade Ubuntu 20.10 to 21.04 20210615 Utilised command line. Wayland would not start so reverted to Ubuntu on Xorg. Everything else seems just fine.

Upgrade Ubuntu 19.10 to 20.04 20200502 No backup required since all of the project work and the system configurations are stored remotely in a git repository and documents are kept on a nextcloud server.

$ wajig update; wajig distupgrade; sudo reboot
$ wajig install update-manager-core
$ sudo do-release-upgrade -d

All went smoothly and after removing snd_hda_intel.dmic_detect=0 from /etc/default/grub sound was fully functional, including the microphones for the first time, noting that the required module snd_soc_skl_hda_dsp was loaded at boot.
