Can anyone advise me. These days, every time I update the system (24.10) I get a shed load of errors. the system still goes on to do some updating, but something must be wrong. Changing servers doesn't seem to make any difference. Also, I've learned to ignore the icon telling me that there is an upgrade to 25.04. It never works and shows no error messages.
