I just did a install of Lubuntu 20.04 (2020-04-22 ISO) where I used manual partitioning, and replaced a prior SDA3 install of focal (I'm guessing last performed before wallpapers were added) with the newer install.
I opted to not-format the partition, and the install looks great, however I was surprised by the 19.10 wallpaper there. When I went into the edit desktop preferences (wallpaper image file), what shows there points to the correct 20.04 image (when filename copy/pasted & viewed in lximage-qt), but I didn't expect to see that image. As I didn't format, my $HOME was left untouched, which would likely explain what I found, however I was surprised & remembered this bug. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-wallpapers in Ubuntu. https://bugs.launchpad.net/bugs/1873685 Title: Wallpaper not updated to 20.04 default after upgrade Status in Lubuntu Artwork: New Status in ubuntu-wallpapers package in Ubuntu: New Bug description: Wallpaper not updated to 20.04 default after upgrade.
