Console output from the upgrade and attempted undo.


I did a "dnf update" and installed a large number of packages.  

Unfortunately, the cleanup script for the third-party docker-engine RPM hung on an "rmmod".  I hit control-C, expecting this to abort and roll back the RPM transaction.  Instead, I seem to have ended up with both versions of the RPMs installed at the same time.  For example:

[beland@localhost ~]$ rpm -q docker-engine
[beland@localhost ~]$ rpm -q sqlite

I tried "dnf history undo 129", intending to undo and redo the update without the problematic docker-engine packages, but this failed with the error:

ValueError: NEVRA was already removed: sqlite-0:3.10.2-1.fc23.x86_64

I'm attaching my console output for debugging purposes.

history undo operates on successful finished transactions. Remove the duplicates first - "dnf remove $(dnf repoquery --duplicated --latest-limit -1 -q)".

I guess the problem then is that cancelling the operation wasn't transaction-safe.  If it couldn't complete it should have rolled back, right?

I tried that command to recover, but it complains:
Error: The operation would result in removing the following protected packages: systemd, dnf.

Feeding that list of packages to "rpm -e --nodeps" did work.  Thanks for the hint, though!  That definitely saved me a ton of manual cleanup.

Unfortunately, rpm "transactions" was not designed as a real transactions. Please file an RFE on rpm if you wish to improve their behaviour. To be honest there is probably zero percent chance they will improve it.
