Hello:

I am unable to install any new apps. When I try to install tightvncserver through CLI–sudo apt-get install tightvncserver–, I get a series of errors: server certificate verification failed; unable to fetch some archives.

I get similar errors with sudo apt-get update.

Any insight on this issue would be most appreciated.

Thanks

What OS image are you starting with? It’s very hard to diagnose an issue without knowing that.
