Manual upgrade

Caution when upgrading from Nextcloud 20.0.9 to Nextcloud 21.0.1! If you are using APCu as memcache.local

# occ config:system:get memcache.local
\OC\Memcache\APCu

you have to put this in your php apcu.ini (e.g. /etc/php/7.4/mods-available/apcu.ini):

apc.enable_cli=1

otherwise you will get in memory trouble during upgrade and in my case the server was down because out of memory.

# cd /var/www/nextcloud/updater && sudo -u www-data php updater.phar
# occ db:add-missing-indices

and since version 19:

# occ db:add-missing-columns
# occ db:add-missing-primary-keys
# occ db:convert-filecache-bigint

Answer the questions...

If you have an own theme proceed with this steps:

# occ config:system:set theme --value <your theme>
# occ maintenance:theme:update

And the apps:

# occ app:update --all

Recreate preview directories

Sometimes something happens and you loose your preview subdirectories. This is a shellscript for recreate the dirs. It takes a long time...

#!/bin/bash

owner=www-data
group=www-data
nextcloud_installdir=/var/www/nextcloud


occ=${nextcloud_installdir}/occ
occ_cmd="/usr/bin/sudo --user=${owner} /usr/bin/php -f ${occ}"

nextcloud_instanceid=$(${occ_cmd} config:system:get instanceid)
nextcloud_datadir=$(${occ_cmd} config:system:get datadirectory)

basedir=${nextcloud_datadir}/appdata_${nextcloud_instanceid}/preview
depth=7

function makesubdirs () {
        local basedir=${1}
        local -i depth=${2}

        (( ${depth} == 0 )) && return
        for dir in ${basedir}/{{0..9},{a..f}}
        do
                [ -d ${dir} ] || {
                        mkdir ${dir}
                        chown ${owner}:${group} ${dir}
                        echo ${dir}
                }
                makesubdirs ${dir} $((depth -1))
        done
}

makesubdirs ${basedir} ${depth}

Set loglevel from commandline

As written at the documentation you can set the following log levels:

Loglevel to start logging at. Valid values are: 0 = Debug, 1 = Info, 2 = Warning, 3 = Error, and 4 = Fatal. The default value is Warning.

You can do this with occ via:

# occ config:system:set loglevel --type integer --value <log level>

or look for the current setting with:

# occ config:system:get loglevel
2

Some tweaks for the theme to disable several things
