Sonarr v3 on ReadyNAS 3138 - CRLfile none

I’m currently running sonarr v2 on my readynas 3138 with OS version 6.10.6 (Debian Jessie-based).
As v2 is EOL, I wanted to update to v3 following the debian instructions on the website. However, on running “apt update”, I’m seeing the following error:

Err:8 https://apt.sonarr.tv/debian jessie Release
server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none

Already tried running “update-ca-certificates”, but that doesn’t seem to solve the issue (not seeing any sonarr related output from that command either by the way).

Anyone got this working on ReadyNAS or knows how to solve this?

Your certificates are invalid on your NAS and need to be updated.
How you do that on the niche OS that is ReadyNAS - who knows.

This is not a Sonarr question and has nothing to do with Sonarr. Seek out your NAS’s support and community methods (if they exist).

ok, thanks for the info. Closing the topic then.
