Is this ok [y/d/N]:

Exiting on user command

Your transaction was saved, rerun it with:

yum load-transaction /tmp/yum_save_tx.2020-07-14.09-42.3PJ6UP.yumtx

 

 

 

 

There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).

The program yum-complete-transaction is found in the yum-utils package.
