After modifying above you need do apt update
then apt upgrade
. apt update
actually gave me some errors/warnings about signature, but doesn't affect apt upgrade
.
Wait until apt upgrade
finishes, then reboot.
Next go to 'Settings' > 'Updates' and update from there, and reboot again.
After that apt update
and apt upgrade
all works fine as normal. No errors any more. I'm actually very surprised it's so smooth for major version update.
It worked for me on 2 different machines - one Thinkpad, another one some Lenovo machine. Both from 15.11 to 20.
