Since some time I'm not getting any updates for my system anymore. I always use the "apt update" command. And sometimes also the software center does update my system.
When I type in apt update I get
Code: Select all

I could also use apt dist-upgrade to upgrade from Debian 9.3 to 9.5. Is it safe to do so when those repositories are not signed. Should I disable all third party repositories before upgrading. Whats the safest way to do so?
Thank you very much for some information concerning my problem.
Thanks
