It is interesting that each of the updates for packages both on upgrade and cleaning seems to be from 1 second to 6 seconds. The process shows 10140 with 1/2 being the installs, and 1/2 being the cleanup and then 10140 verifies.

After doing the dnf system-upgrade reboot It comes up with a graphic screen that just shows it is doing upgrade and to not shut down. Very little info. Ctrl-ESC does show it doing the process, and shows each package and the count as it goes with time of each step. Was able to do Ctrl-Alt-F? Think it was F6 that finally gave a command line login. Was able to login as root, and just ran top command. Noticed that CPU was showing 100% other numbers all seemed low. Never saw CPU change from 100%, and it only showed dnf process as high activity. > _____________ __________________________________ > users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx > Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines > List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx +------------------------------------------------------------+ Michael D.
