Upgrading to Ubuntu 18.04

So far I upgraded three Ubuntu machines from 16.04 LTS to 18.04 LTS. Just my work laptop is left. A little checklist for future upgrades:

Before upgrading

• Cleanup unneeded packages to minimize the need to update

Upgrade!

• Do the actual upgrade to Ubuntu 18.04:

  sudo apt update
  sudo do-release-upgrade

• Add PPA for Gnome + XMonad again:

  sudo add-apt-repository ppa:gekkio/xmonad
  sudo apt-get update
  sudo apt-get install gnome-session-xmonad

• Select GNOME + XMonad session at login

Polish

• Install Gnome tweak tool:

  sudo apt install gnome-tweak-tool

• Use gnome-tweaks to hide desktop icons (category by category, hiding all at once resets the wallpaper as well!)
• Backup wineprefix under ~/.wine, let wine 3.0 initialize the default wineprefix again, e.g. by executing winecfg. Then copy relevant programs back into the wineprefix

Update: previously it was needed to adapt the Gnome configuration in regards to top/bottom panels. If this features ever surfaces again:

1. Install dconf-editor
2. Go to entry org > gnome > gnome-panel > layout
3. For key toplevel-id-list remove 'bottom-panel' from list
