Similar or same problem as Angel2035. Before update did a Timeshift backup (manually) for a most recent backup. After the update read angel2035’s post. Told Timeshift to make another manual backup, it started and then quit without writing anything to the backup drive. I see where I ran the backup in the Timeshift gui.log but no errors there and no backup. log. I back up every day automatically and have both a gui.log and backup.log for each successful backup. Kernel 5.15.71-1 Stable Manjo KDE Plasma desktop. EXT4 FS.
Since my original post I have been examining the gui.log for the pre update backup and the post update backup attempt which was unsuccessful. Rather than taking up space here could the mods please open a new thread for this Timeshift problem and I will share the gui.log diffs and hopefully find out how to rectify for myself, Angel2035 and any other user that experiences this…thanks…
