Hello,
I am not new to linux but I am new to opensuse. I have had the above error when connecting to this same server on my other PC running linux mint, and so I followed the directions of many posts elsewhere online and connected with openssl (using the command “openssl s_client -connect [server]:21 -starttls ftp”), copied the certificate, and put it in the file “/etc/ssl/certs/ca-certificates.crt” then put this reference to the file:
set ssl:ca-file "/etc/ssl/certs/ca-certificates.crt"
in /etc/lftp.conf. On that other PC this worked, but on the machine running opensuse I still get the “unable to get local issuer certificate” error.
