The updater over web interface gives the error message: cURL error 60: SSL certificate problem: unable to get local issuer certificate
The updater does not work. However, marketplace works and can also download and apply upgrades. In my understanding both use cUrl for downloading stuff. What is the difference between these 2 use cases? What does the updater makes different than the marketplace?
Long version: I understand this has to do with my server setup. I have followed the guides I found online (downloading the certificates and linking them in the php.ini) without success.
My server is a linux box in the intranet, no access from outside. Since it is local, I cannot use letsencrypt, so I have created a self signed certificate for accessing owncloud. For my private use in LAN, this is good enough and works fine.
Would it make a difference if I run owncloud in http (instead of https) just for upgrading?
Where does the upgrade script download the updates from, so I can try out if I can download them via the command line?
Furthermore, also the occ script fails. I do not know if this is related to the same problem.
sudo -u www-data php occ upgrade
→ ownCloud is already latest version
(no, it is not. I have 10.8.0.4)
I just want to avoid having to do a fully manual upgrade each time…
