I hear what you are saying. I don't know you or trevor - I see I actually joined before either of youscottro wrote: ↑2020/12/08 19:21:55At any rate, there is no in place upgrade supported by CentOS. This is a CentOS forum, so though folks may think it is a matter of moderators sticking together, whatever article was used to attempt the upgrade is something by the article's author, that may have worked for them. So, while it may seem snarky, saying contact them is actually the most logical response. Trevor does more work than any of the other mods on this forum, and spends a great deal of his spare time helping those who post here by answering questions.
The only issue here for me is that the centlinux site doesn't have any kind of warning or disclaimer. There's even a comment by someone who had the same error message as me - but looks like he was able to work around it.
I just restored /boot, /etc, /var, and /usr from my backups. Then ran 'rsync' to delete files that weren't on the backups (so had been created since the backup). Now at least it will boot, though I obviously have a clean reinstall in my near future.
