Resolution

Upgrade from Ubuntu 18.04 LTS to 20.04 LTS Perform the following steps to upgrade Ubuntu from 18.04 SP1 20.04 to resolve the issue. There are several things that you must take into account before upgrading. Go to Software & Updates > Updates, select For long-term support versions (Figure 1). Figure 1. Ubuntu Software & UpdatesPress "Ctrl-Alt-T" to open the Terminal and run below command: sudo apt update Then run below command: sudo apt dist-upgrade The upgrade process can be done using the Ubuntu update manager or on the command line. The Ubuntu update manager starts showing a prompt for an upgrade to 20.04 once the first dot release of Ubuntu 20.04 LTS (that is 20.04.1) is released. The typical timeframe for this is around three months after the official release. Once this functionality is enabled, you see the following prompt (Figure 2). Follow the prompt to upgrade. Figure 2. Ubuntu Software Updater Alternative options to upgrade On the command line, you can run update-manager -c to initiate the upgrade. Like the do-release-update tool, you can run the above with the optional -d flag to get the "development" release ahead of the 20.04.1 availability. sudo update-manager -c sudo update-manager -c -d On the command line, you can also run /usr/lib/ubuntu-release-upgrader/check-new-release-gtk. sudo /usr/lib/ubuntu-release-upgrader/check-new-release-gt In general, you can control what Ubuntu release upgrades are available, regardless of which tool you use and run. This can be done by editing the following configuration file: /etc/update-manager/release-upgrades Here, you can check the line Prompt=XXXX, whereby: Never - no upgrades are offered.Normal - supported release that immediately succeeds the currently running release is offered.LTS - LTS releases are offered.
