Removing modules
In general, to remove a module installed on your system, use the following command:
$ sudo dnf module remove MODULE:STREAM/PROFILE
Advanced
There is a situation when a specific package has been installed first, and then a module has been installed after that. Example:
$ sudo dnf install ruby $ sudo dnf module install ruby:2.6/default
In this case, running the dnf module remove
command would not remove the ruby
package, as DNF remembers that package has been explicitly installed.
To make the ruby
package uninstalled with the dnf module remove
command, run the following:
$ sudo dnf mark group ruby $ sudo dnf module remove ruby:2.6/default
That is because DNF remembers a reason why a package has been installed. There are three, sorted from the strongest:
-
user
-
group
-
dependency
Because modules use the group reason, which is weker than user used by the dnf install
command, the package stays on the system after running the dnf module remove
command. "Downgrading" it to group, however, makes the dnf module remove
remove it as well.
