I changed from Ubuntu 20.04 to 24.04. Now the clock shows the wrong time (3 hours early). When I opened the system settings to fix this, the program crushes when I click on "Date and time". Can anybody help me?
I'm trying to troubleshoot a firewall rule causing packets to drop.
I set up TRACE and got the following:

is only available from another source
E: Package 'postgresql' has no installation candidate
