My Ubuntu workstation was frozen, so I used the power button to shut it down.
Next time I booted, it displays this message and remains on a black screen with nothing but this message:
/dev/sdb1: clean, 215539/15237120 files, 3398675/60918272 blocks
From here (using some other answers I found on this forum, such as Booting problem after upgrade, /dev/sda2 clean) I managed to login to the command line (no desktop) with Alt+F1 or Alt+F2 (is there a difference?).
All the suggestions in the threads I found involved updating or reinstalling certain packages (note: I'm using Intel onboard graphics, not a Nvidia GPU. And the integrated graphics was working just fine prior to this, there have been no hardware changes whatsoever), but I am now having an internet connection issue where the machine is unable to connect and just gives a bunch of "Temporary failure in name resolution" errors.
I can replicate this with ping google.com, which returns the error message ping: google.com: Temporary failure in name resolution.
One thing I've tried was editing my /etc/resolv.conf file and adding the line nameserver 8.8.8.8 following the instructions here: https://www.tecmint.com/resolve-temporary-failure-in-name-resolution/ . Not only did this not work, but after a reboot the file reverted to what it was before.
I'm completely at a loss here: I'm unable to boot to the desktop, and I can't connect to any internet sources to update packages, which seems to be the only solution for the boot issue. Any help will be greatly appreciated.
