Problems with upgrade to 18.04 from 16.04

Question

After dist-upgrade my system on 16.04 I've received such problems - some gui's don't appear correctly, can't install new packages and after command apt-get -f install received such printing

How could I repair such issues?

Solution

1. After upgrading you must reboot.

2. Make sure you sign-on selecting Unity from the drop down gear menu:

   

3. After signing in the first thing you must do is open a terminal and run:

   sudo apt update

   sudo apt upgrade

18.04 is not ready for upgrading 16.04 in place. That comes after the first point release, 18.04.1, which comes in June.

[SDsolar]

This is a great question that calls for an authoritative reference answer.

[WinEunuuchs2Unix]

This is too late to help you but everyone reading should consider upgrading 16.04 to 18.04 in a test environment (cloned partition) first. You can manually do this booting with a Live USB or use this automated script without booting a Live USB: askubuntu.com/questions/1028604/…
