4.3 Ubuntu Upgrade
$ wajig update $ wajig distupgrade $ do-release-upgrade
If for some reason that is problematic then the traditional upgrade
path is simply to edit the
/etc/apt/sources.list file to
identify the new repository. There may be further files in
/etc/apt/sources.list.d/ that also require updating.
In the following example the distribution is updated from bionic to focal.
$ sudo apt update; sudo apt install python3-pip $ sudo pip3 install wajig; wajig update; wajig distupgrade $ sudo perl -pi.bak -e 's|bionic|focal|g' /etc/apt/sources.list $ wajig update; wajig distupgrade
This approach works but is not generally recommended.
