I have been using 20.04 on a RPi4/4GB since its release and am very pleased with the performance.
Today, I upgraded to 20.10 and all works well, except for a couple of issues:
-
After every boot, a "System program problem detected" window opens. It has no "details" tab, so there is no hint of what is the problem. I have checked the /var/log/syslog file, but there doesn't appear to be anything obvious. How can I found out what is the problem?
-
Chromium takes about 90 seconds to open to my home page (for 20.04 was 2-3 seconds). I have tried removing and reinstalling, but that does not resolve the issue. Once my home page opens, chromium responds normally.
The following entries from /var/log/syslog relate to the problem. As you can see from the timestamps, the whole process takes 1 minute 28 seconds and includes many "DENIED" messages.
