NethServer Version: 7.4 1708 fully updated
Module: Nextcloud 13
Continuing the discussion from Nextcloud 13 - Call for QA!:
It seems like the package nethserver-nextcloud from nethserver-testing is needed to make Nextcloud 13 work. When you install from Software Center or with yum without “Nethserver-testing” repo, you can’t connect to Nextcloud anymore:
When you do yum install --enablerepo=nethserver-testing nethserver-nextcloud
it works again.
EDIT:
Nextcloud 13 is not in nethserver-updates anymore, check this post
