I just installed a completely fresh system in a VM with Ubuntu Server 18.04. The only extra package I selected on OS installation was PostgreSQL 10. Then after a restart I upgraded everything:
sudo apt update sudo apt upgrade
Now I tried this:
sudo apt install chromium-browser
And got some text that implies that the package is missing (can't copy the text out of the VMware window). What's up here? Is Ubuntu already broken on installation? Do I need other obscure package sources?
