How is it good if
I'd try

Hi Shruggy

Thanks for the reply - yes I have done that as well but still have problems.
It was in the middle of yum -y update when power went off.
Then system wouldn't boot - dropped to emergency shell ☹️
I had to work out what was happening.
I managed to repair the LVM and filestsyem.
It now boots up 'fine'
I can use the rpm command but not yum.

Thanks again

A bit of an update...
yum only seems to fail when running the transaction itself - everything upto that point is ok.
So I got yum to download only dnf - the next iteration package manager.
Once the rpm's were downloaded I moved them all into same folder and manually installed with rpm command.

dnf check-update -> works fine and finds packaged to update
dnf update -> works and updates as expected.

I have a working system again but broken yum?
Was thinking of maybe removing yum via dnf and re-installing but not yet when things seem to be ok 😂

# dnf -y remove yum yum-metadata-parser
# rm -Rf /etc/yum

Does what I wanted - no more yum!
All is good 😂
