I am running Ubuntu 20.04 LTS. Two weeks ago the following message started to pop up during the startup process: "Certificates are not valid, you must be logged in as root to create new ones." I really do not know what I've done to cause such behavior.

pop up messsage

Could anyone help me to solve this little issue? Thanks in advance.

    A message like this points more to certificates that have expired rather than something you may have done. The question is really more about which certificates have expired, as it doesn’t seem to be preventing you from using the machine. What message do you see when you run sudo update-ca-certificates in Terminal? 🤔

  • This is the message after running the sudo update-ca-certificates command: 'Updating certificates in /etc/ssl/certs... 0 added, 0 removed; done. Running hooks in /etc/ca-certificates/update.d... done. done.'

  • Hmm ... we'll need to see if there is anything in the logs to say which certificates need to be updated, then. Could you take a look in /var/log/syslog to see if there are any messages complaining about certificates from around the time you signed into the machine and received this error?

  • Just a simple check: is your system date and time (and timezone) correct?
