Migrating to xUbuntu focal 20.04 LTS
This post describes the update of xUbuntu 18.04 LTS to xUbuntu 20.04 LTS (focal). The upgrade process has been launched with
sudo do-release-upgrade -dand everything went smoothly except for two things:
- First, chromium now seems to be available only through snap. It does not require to do anything special but it is something to remember.
- Second, xscreensaver needs to be deactivated for the upgrade. I did it and have not fixed this issue since (so the session is just locked with the standard xfce tool and displays a black screen).
After the upgrade, these minor fixes have been performed:
- A few repositories have been deactivated for the update, including **R** and nextcloud client. I reactivated them by (for **R**) adding the line
deb https://cloud.r-project.org/bin/linux/ubuntu focal-cran40to the file
/etc/apt/sources.listand (for nextcloud) by editing the file
/etc/apt/sources.list.d/nextcloud-devs-ubuntu-client-DIST.listto uncomment the line
deb http://ppa.launchpad.net/nextcloud-devs/client/ubuntu focal mainThen,
sudo apt update sudo apt upgradeupgraded everything.
- The software gcstar is no more available. I downloaded the version available for Ubuntu 18.04 LTS at https://launchpad.net/ubuntu/+source/gcstar/ and installed it with:
sudo dpkg -i gcstar_1.7.1+repack-1_all.deb sudo apt install -fHowever, this temporary fix is still unsatisfactory and I hope that gcstar will somehow reappear in the Ubuntu official software library.
