Upgrade WSL/WSL2 Ubuntu version to 20.04 LTS
Its the time of the year again to upgrade Ubuntu version in WSL/WSL2 since the Ubuntu 20.04 LTS came out last week.
Please follow along the following steps in your WSL console to upgrade to the new version:
Check installed Ubuntu version
Take a note of your current Ubuntu version by running the following command:
No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04.4 LTS Release: 18.04 Codename: bionic
**Upgrading to 20.04 should work seamlessly when upgrading from 18.04. However if you are on older versions then the suggested path should be upgrading first to 18.04 from 16.04 for example.
Upgrade installed packages
sudo apt update sudo apt list --upgradable sudo apt upgrade
Remove unused packages
sudo apt --purge autoremove
Install update-manager-core package if not already installed
sudo apt install update-manager-core
Upgrade to 20.04
If you receive the following message:
Checking for a new Ubuntu release There is no development version of an LTS available. To upgrade to the latest non-LTS develoment release set Prompt=normal in /etc/update-manager/release-upgrades.
Then do an upgrade forcefully using the following command:
sudo do-release-upgrade -d
Finally check the version after upgrade is done:
and you should receive the following similar output:
No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 20.04 LTS Release: 20.04 Codename: focal
