Hi Richard,

DNF uses three types of locks (metadata, download and rpmdb lock) to allow more or less parallel execution of DNF commands.

IIRC, the actual issue with kmods has been already resolved in upstream by switching rpmdb lock to blocking mode.

I remember frequently (to my dismay) getting messages from yum saying that another process had a lock on the RPM database.

Due to a recent rash of issues with the akmods package I have been investigating why the kmods are not getting installed.

Out of curiosity I tried running two dnf update instances in two different terminals and I did not get the message, in fact it acted like nothing was wrong!

Of course I hit "n" to not install the updates so I'm not sure what would happen if I had hit "y"...

Am I missing something here?

Thanks,
Richard
