To install Nextcloud on Ubuntu or other Linux use command:

sudo snap install nextcloud

After installation snap package check installation status

sudo snap changes nextcloud

To change default http and https ports use commands:

sudo snap set nextcloud ports.http=81
sudo snap set nextcloud ports.https=444

In Nginx proxy server configuration file change proxy_pass default port to 81:

Nextcloud’s automatic hostname detection can fail when behind a proxy; you might notice it redirecting incorrectly. If this happens, override the automatic detection (including the port if necessary), e.g.:

sudo nextcloud.occ config:system:set overwritehost --value="example.com:81"

Nextcloud and Nginx https proxy

If You use Nginx as https frontend and nextcloud as http backend – You neet co change /var/snap/nextcloud/20498/nextcloud/config.php insert the foloving lines:

  'overwrite.cli.url' => 'https://example.host',
  'overwriteprotocol' => 'https',

In Nginx http config file insert 301 redirect to https:

return 301 https://example.host$request_uri;

By default, PHP will use 128M as the memory limit. If you notice images not getting previews generated, or errors about memory exhaustion in your Nextcloud log, you may need to set this to a higher value.

If you’d like to set the memory limit to a higher value (say, 512M), run:

sudo snap set nextcloud php.memory-limit=512M

To set it to be unlimited (not recommended), use -1:

sudo snap set nextcloud php.memory-limit=-1

By default the cronjob interval is 15 minutes. To adjust it (say, 10 minutes) simply run:

sudo snap set nextcloud nextcloud.cron-interval=10m

Rescan all files for all users with occ console command:

sudo -u username php occ files:scan --all
