Log/Installation Cleanup after Migration from NextcloudPi to Promox LXC Docker Installation

ℹ️ Support

Support intro

Dear community Members,

I was able to migrate my NextcloudPi Instance to a Proxmox LXC Docker installation behind NGINX. Migration was done based on the user-data (/data) and the mariadb database. I did not touched the nextcloud installation files of my docker installation.

I had some serious challenges (for my skillset) with the migration process, e.g. i was not able to drop the old Database created with the docker deployment which was called nextcloud-db, therefore switching to “nextcloud” as the new (and old nextcloudpi) name of the database, and so and and so forth. however after 4-6 h of fiddeling around and following various topics inside this forum, the nextcloud installation is up and running again.
for example the permissions were not correctly set even with using rsyn -Aax etc.

chown -R www-data:www-data /mnt/.docker-data/volumes/nextcloud/nextcloud-data/data
find /mnt/.docker-data/volumes/nextcloud/nextcloud-data/data/ -type d -exec chmod 750 {} ;
find /mnt/.docker-data/volumes/nextcloud/nextcloud-data/data/ -type f -exec chmod 640 {} ;

sortet such stuff. 2FA was broken as well, occ was helpfull with deactivating the 2FA for the users so to login again, recreating 2FA credentials again etc.

i can login into my existing admin accound, i was able to reconnect my client pc and android app as well as sync is up and running again.

however my log states a lot of errors were i dont know how to start or how to understand the problems of the existing mirgrated installation. Therefore I would ask for help of you experts.

here are the latest outputs of my log

Nextcloud version (eg, 20.0.5):
php occ status

  • installed: true
  • version: 28.0.4.1
  • versionstring: 28.0.4
  • edition:
  • maintenance: false
  • needsDbUpgrade: false
  • productname: Nextcloud
  • extendedSupport: false

Operating system and version (eg, Ubuntu 20.04): Debian 12 as Proxmox LXC
Apache or nginx version (eg, Apache 2.4.25): replace me
PHP version (eg, 7.4): replace me

so this is a filesharing problem within two clients on my server? i replaced the two user-names, however one shares files with the other in their auto-upload folders. however both users did reactivated their iphone apps on the new server web interface since the migration and the error is now even more present in the logs. this is annoying. in addition, the autoupload functions their iphones do not work anymore. I’m very lost here, the solutions discussed in the forum were implemented with the ngix advanced settings? these did not helped (ocm-provider settings).

  1. dns_get_record(): A temporary server error occurred. at /var/www/html/lib/private/Http/Client/DnsPinMiddleware.php#111 (error level of PHP)

my nginx advanced settings are providing the ocm redirect?

any help would be awesome!

I am facing a very similar issue after migrating my Nextcloud to a new domain.

I assume it has to to with some shares pointing to an old user/domain that is not available anymore.

Did you play around with the database to find potential shares, that might be the culprits?

4

I asked the main user that was throwing the error messages to delete all shares and recreate them. in this process we found a share against a user that was not existent anymore, at the moment we deleted the share, no more errors occured. therefore the installation was rock solid and the mirgration process was totaly fine and nice to follow with the intorduction provided from the community and the official nextcloud wiki pages. the thread can be closed, however i would have wished for a more clear log-report about teh issue as it is for me absolutly not readable that this ocm error and dns_get_record() issues are pointing to a problem in user-shares.
