I Found that there was a symbolic link in /etc/ssl/certs to a non-existent file. So how do I recover after removing the symbolic link?

[Steve Beattie (sbeattie)]

Hey Vern,

Sorry you were having difficulties. 'sudo apt install -f' should cause apt to attempt to finish installing packages that had problems during the post install phase, where the error that is tripped over (like the dangling symlink in /etc/ssl/certs) has been resolved.
