You cannot use apt-get upgrade
, as this command will not remove packages. We constantly need to refactor our packages to support newer products, which means some times a single large package will be spitted into multiple smaller packages to improve code reuse. When you run apt-get upgrade
, some of those packages will stay at their old versions, which will not work correctly with the newer packages.
This is a common issue in Debian derivatives. For example, Proxmox VE also can’t be upgraded with apt-get upgrade
.
The supported upgrade method is via rsetup
.
