Nextcloud server packaged as a snap. It consists of:
There are a number of releases available. By default you'll get the newest stable one, but you may be interested in others.
After install, assuming you and the device on which it was installed are on the
same network, you should be able to reach the Nextcloud installation by visiting
<hostname>.local in your browser. If your hostname is
localhost.localdomain, like on an Ubuntu Core device,
be used instead.
Upon visiting the Nextcloud installation for the first time, you'll be prompted for an admin username and password. After you provide that information you'll be logged in and able to create users, install apps, and upload files.
Note that this snap includes a service that runs cron.php every 15 minutes, which will automatically change the cron admin setting to Cron for you.
Also note that the interface providing the ability to access removable media is
not automatically connected upon install, so if you'd like to use external
storage (or otherwise use a device in
/mnt for data), you need to
give the snap permission to access removable media by connecting that
$ sudo snap connect nextcloud:removable-media
The System application requires a bit more access to the system than the snap uses by default (e.g. the ability to monitor network hardware, etc.). If you'd like to utilize those features, you'll need to connect the interface that allows that kind of access:
$ sudo snap connect nextcloud:network-observe
Beyond the typical Nextcloud configuration (either by using
/var/snap/nextcloud/current/nextcloud/config/config.php), the snap
exposes extra configuration options via the
snap set command.
By default, the snap will listen on port 80. If you enable HTTPS, it will listen on both 80 and 443, and HTTP traffic will be redirected to HTTPS. But perhaps you're putting the snap behind a proxy of some kind, in which case you probably want to change those ports.
If you'd like to change the HTTP port (say, to port 81), run:
$ sudo snap set nextcloud ports.http=81
To change the HTTPS port (say, to port 444), run:
$ sudo snap set nextcloud ports.https=444
Note that, assuming HTTPS is enabled, this will cause HTTP traffic to be redirected to port 444. You can specify both of these simultaneously as well:
$ sudo snap set nextcloud ports.http=81 ports.https=444
Note: Let's Encrypt will expect that Nextcloud is exposed on ports 80 and 443. If you change ports and don't put Nextcloud behind a proxy such that ports 80 and 443 are sent to Nextcloud for that domain name, Let's Encrypt will be unable to verify ownership of your domain and will not grant certificates.
Also note: 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"
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
If you want to disable the cronjob completely, run:
$ sudo snap set nextcloud nextcloud.cron-interval=-1
To reenable it again simply set the
nextcloud.cron-interval snap variable to a value that isn't
By default, the snap does not enable HTTP compression. To enable it, run:
$ sudo snap set nextcloud http.compression=true
To disable it, run:
$ sudo snap set nextcloud http.compression=false
By default, the snap installs itself in production mode, which prevents Apache and PHP from providing any detailed version or library information in the HTTP headers and error pages. Debug mode can be enabled with:
$ sudo snap set nextcloud mode=debug
"debug" and "production" are the only valid modes.
There are a few CLI utilities included:
occconfiguration tool. You can always edit the config file directly (
/var/snap/nextcloud/current/nextcloud/config/config.php) but the configuration tool provides a CLI interface for it. See
nextcloud.occ -hfor more information. Note that it requires
nextcloud.enable-https -hfor more information. Note that it requires
nextcloud.export -hfor more information. Note that it requires
nextcloud.export). By default this imports the database, config, and data. See
nextcloud.import -hfor more information. Note that it requires
If you change something in the snap, build it, install it, and you can run a suite of acceptance tests against it. The tests are written in ruby, using capybara and rspec. To run the tests, you first need to install a few dependencies:
$ sudo apt install gcc g++ make qt5-default libqt5webkit5-dev ruby-dev zlib1g-dev $ sudo gem install bundle $ cd tests/ $ bundle install
Additionally, if you do not have X configured, install the following for a 'fake' X server.
$ sudo apt install xvfb
Make sure the snap has a user called "admin" with password "admin" (used for login tests):
$ sudo nextcloud.manual-install admin admin
And finally, run the tests:
$ cd tests/ $ rake test
