Some of the libraries that have been updated post-7.8 will still be left around and could cause problems. They can be removed but that may cause problems too and I'd only consider it on a machine with console access. (If packages were updated while on -current the sane way to recover from that after "upgrading backwards" would be to remove all packages and reinstall from release/-stable). > On Mon, Dec 1, 2025 at 4:29=E2=80=AFAM Robert Alessi <[email protected]= > et> > wrote: > >> Hi misc@, >> >> Yesterday, I wanted to upgrade my VPS to 7.8, but I did >> >> sysupgrade -ns >> >> This was clearly a mistake.
