Never mind this.
AFAIK that’s not necessary anymore:
Please provide the output of:
journalctl --boot=-1 --priority=4 --no-pager
Where:
--boot=-1is for the last bootup that you had an error. Adjust this to-1for the previous boot,-2for the one before that,-3for the one before that, and so on and so forth;--priority=4limits the output to be Warnings and Errors only; and--no-pagerjust formats it nicely so that we can use it here on the forum.
