Upgrading Nextcloud Tips And Tricks

I upgraded Nextcloud from version 25 to version 27 and it was an oddysey full of perils. Afterwards I found a simpler way in a documentation, but regular web search was not much helpful, so it took longer. Who has time to read through the manual? Well, I should have.

try to update via web interface before system update, I didn’t do that, maybe it would work
Nextcloud 25 supports PHP 7.4
Nextcloud 26 supports PHP 8.1 (recommended), 8.2
Nextcloud 27 supports PHP 8.1, 8.2 (recommended)
Debian 12 upgraded PHP from 7.4 to 8.2
do not download releases from https://github.com/nextcloud/server/releases/tag/v26.0.2, they are missing dependencies and require git submodule …shame that releases do not have .git directories….
download releases from here https://nextcloud.com/changelog which include dependencies
occ cannot upgrade to a new major version (25 -> 26), only web updater or updater.phar can - it downloads and runs occ later
to run “web updater” from CLI: sudo -u www-data php updater.phar
major versions cannot be skipped, upgrade needs to go through each one (25 -> 26 -> 27)
manual upgrade - https://docs.nextcloud.com/server/latest/admin_manual/maintenance/manual_upgrade.html - important page
I tried to install an older version of PHP from https://packages.sury.org/php/README.txt, but in the end wasn’t necessary since v26 supported in 8.2
run php occ db:add-missing-indices after upgrades

Issues and How to Solve Them

Verifing Integrity Failed

Updater downloads a new version, but integrity check fails.

Verifying integrity
Parsing response failed.
Show detailed response

You need to increase maximum memory for a request, change from 128M to 512M. An update has ~300MB. There is also a message in sanity check in admin interface:

root@starz:/etc/php/8.2/fpm# vim php.ini

; Maximum amount of memory a script may consume
; https://php.net/memory-limit
memory_limit = 512M

systemctl restart php8.2-fpm.service

Press “Retry” button. If there is “step in progress” message, remove a lock with:

rm ../nextcloud_data/updater-fdsfasdfa/.step

“Nextcloud is already latest version”

occ cannot upgrade to new major version

according to https://help.nextcloud.com/t/web-console-shows-upgrade-available-but-occ-says-latest-already-installed/88439/2 and https://docs.nextcloud.com/server/16/admin_manual/maintenance/update.html#using-the-command-line-based-updater you should run something like:

sudo -u www-data php updater.phar

Add Redis Caching

Install Redis:

apt-get install redis

Add to config/config.php to use Redis cache everywhere:

  'memcache.local' => '\OC\Memcache\Redis',
  'memcache.distributed' => '\OC\Memcache\Redis',
  'memcache.locking' => '\OC\Memcache\Redis',
  'redis' => [
    'host' => 'localhost',
    'port' => 6379,
  ],

Telephone Warning

Add to config/config.php:

'default_phone_region' => 'SK',

Required PHP Dependendencies

apt-get install php8.2-mysql php8.2-redis php8.2-xml php8.2-zip php8.2-mbstring php8.2-gd php8.2-curl php8.2-intl php8.2-gmp php8.2-bcmath

“This version of Nextcloud is not compatible with PHP>=8.2”

This version of Nextcloud is not compatible with PHP>=8.2.
You are currently running 8.2.7.

v25 is not compatible, but v26 is, manual upgrade is needed, because CLI scripts don’t work either

PHP 5

php5 occ --help

Tried with PHP 5 I still had….

You need to switch to www-data or user which owns config/config.php:

sudo -u www-data php occ --help
sudo su -l www-data -s /bin/bash and run commands

You need to specify also shell, see the point above.

Exception: Updates between multiple major versions and downgrades are unsupported.

The update was unsuccessful. For more information check our forum post covering this issue.

Skipping major version is not supported, e.g. 25 -> 27. The correct upgrade path is 25 -> 26 -> 27.

Copy Stuff From Old Nextcloud

Copy config files, plugins you use and set permissions. I copied only two plugins, I don’t care that much about others. In the end others are still enabled even if I haven’t copied them, not sure what is the difference.

cp nextcloud_old/config/config.php nextcloud/config/
cp -r nextcloud_old/apps/bookmarks nextcloud/apps/
cp -r nextcloud_old/apps/notes nextcloud/apps/

chown -R www-data:www-data nextcloud
find nextcloud/ -type d -exec chmod 750 {} \;
find nextcloud/ -type f -exec chmod 640 {} \;
