I installed Ubuntu 18.04 off a DVD last night.
I added a few basics like gcc, make, build-essential, manpages-dev, dkms, git, a wifi driver (using dkms), curl, gnupg, brave-browser, and Steam. Then today tried to upgrade the OS to version 20.04 via the Software Updater GUI. It got as far as "Installing the Upgrades"
"Focal" window says:
Unpacking libselinux1 (amd64)
and in the terminal below:
Preparing to unpack .../libpam0g_1.3.1-5ubuntu4.1_amd64.deb ...

There's this window off the to side named "Frontend" that says "Configuring libpamOg:amd64" and has a checkbox that says "Restart services during package upgrades without asking?" Toggling it does nothing.
I can't open the "Files" app nor the System Settings app.
What should I do now?
