On my Ubuntu 17.04 I recently started to get errors concerning missing packages when doing sudo apt update, which makes sense since 17.04 is no longer supported. So I replace the contents of my /etc/apt/sources.list with the following:
deb http://archive.ubuntu.com/ubuntu artful main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu artful-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu artful-security main restricted universe multiverse
And it worked OK. Later I upgraded it to 17.10, but the sources.list is still the same, it doesn't seem to cause any problems, but I sort of expected it to be filled with 17.10 repos after the upgrade.
Is this the way it is supposed to work?
