Re: [lftp] certificated validation
Your software is very tricky. After --with-ssl=yes openssl is not denoted (in the bottom line) but doing some TLS operation! After set ssl:ca-path /etc/ssl/certs/ OR set ssl:ca-file /etc/ssl/certs/ca-certificates.crt lftp says: --- 234 AUTH TLS successful --- OPTS MLST modify;perm;size;type;UNIX.group;UNIX.mode;UNIX.owner; Certificate depth: 0; subject: /OU=Domain Control Validated/OU=PositiveSSL/CN=s1.tarhelydiktator.eu; issuer: /C=GB/ST=Greater Manchester/L=Salford/O=COMODO CA Limited/CN=PositiveSSL CA 2 ERROR: Certificate verification: unable to get local issuer certificate SSL_connect: unable to get local issuer certificate Could you test it and fix it?
