HELP! I just wanted to remove some codecs that I don't need but dfn removed also the dependencies and that's much more! Is there a way to undo this somehow?

Run sudo dnf history or sudo dnf history info last or sudo dnf history info last-1 to see previous transactions dnf performed. dnf history undo last or dnf history undo $number will revert the removal.

And btw: no need to shout help in the title: It is obvious that anybody posting a question here is seeking help!

I know that dnf is intended as a replacement/upgrade for yum, and yum does have an undo command. (You can either specify the transaction number from the history, or simply use last.) I'd think that carrying this forward would be a no-brainer, but it's possible that it hasn't been implemented as yet. Does anybody know?

It has not been implemented in dnf - I don't know if it will in the future. To me, this is a step backwards...

I haven't moved to dnf yet, so I have to ask: can you currently examine its history and see what was removed? If so, you should be able to use that to install the packages again, rather like a manual version of undoing the transaction.

Actually there is with sudo dnf history undo last depending of the repository. `

@luya, Oh yea, true. I didn't know that. Thanks! @sideburns: Looks like you can undo last transactions. You can also look into them using dnf history info last or dnf history info last-2...

Using that command will only update those packages you have installed; it won't install anything (except for new dependencies, or new kernels of course) that isn't already there.
