Install ca-certificates #1
Description
Without the ca-certificates package certain functions will not work, including TLS connections.
Error:
Establishing connection to imap.gmail.com:993 (main-remote)
ERROR: No CA certificates and no server fingerprints configured. You must configure at least something, otherwise having SSL helps nothing.
After installing ca-certificates, the offlineimaprc file needs to contain the line:
sslcacertfile = /etc/ssl/certs/ca-certificates.crt
