FAQ

Checks

Your web server is not properly set up to resolve `.well-known` URLs, failed on: `/.well-known/webfinger`

Failing check seems to be a bug

Your installation has no default phone region set.

nextcloud.occ config:system:set default_phone_region --value="NL"

No memory cache has been configured.

documented

This instance is running in debug mode

occ config:system:get debug

and set

occ config:system:set debug --value false --type bool

Find previous versions of file

"Versioning creates backups of files which are accessible via the Versions tab on the Details sidebar" but WHERE is that sidebar?? Somehow you do get that if you go to the file via Activities

Access through untrusted domain

trusted_domains setting, check

occ config:system:get trusted_domains

and add your domain/network there

occ config:system:set trusted_domains 1 --value="192.168.1.0/24"

etc

Run occ as web user

sudo -u www-data php occ whatevercommand

Upgrading

Web upgrader is under "Overview", not "Version"

On command line

sudo -u www-data php --define apc.enable_cli=1 /var/www/nextcloud/updater/updater.phar

run this again to upgrade to next major version

Check for expected files, The following extra files have been found:

Probably files in install root dir

Stops at X Create backup

Check data/updater.log

Stop maintenance mode

runuser -u www-data -- php occ maintenance:mode --off

apache error log: Client denied by server configuration: .ocdata

That's from the Overview test cycle, so in fact a good sign

Authentication

nextcloud and yubikey

Works using the U2F app

Location of the logfile

Could be:

/var/www/nextcloud/data/nextcloud.log

or where you told it to be in config.php

File encoding for /<user>/files/foo.txt is not UTF-8. This may cause problems.

file contains non-UTF-8 characters

 

The files you are trying to upload exceed the maximum size for file uploads on this server.

???

Access forbidden CSRF check failed

Maybe you have the site open in multiple tabs?

Import data

occ files:scan <userid>

or in snap:

(sudo) nextcloud.occ files:scan <userid>

Uknown user 1

It needs the user ID, not name

Mail

https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/email_configuration.html

Request does not pass strict cookie check

clear cookies?

Unexpected error during account creation

Try enabling mail_smtpdebug

MP4 not playing

Could be HCEV/H.265 which is not supported by browsers because of patents. Try converting with ffmpeg.

Update needed

And occ upgrade failing, try setting version in config.php to version reported by occ --version

The PHP OPcache module is not loaded

try uncommenting

opcache.memory_consumption

and remember to restart php-fpm as well as apache

Nextcloud Office is not configured

This installation does not have a built in server. Install it from the App Store. Collabora?

Nextcloud using ldap backend

Change ldap admin password

occ ldap:set-config "s01" "ldap_agent_password" "newpass123"

ldap user login failed

Very well hidden: in LDAP/AD Configuration under "Advanced" check "Configuration Active"

occ ldap:show-config
 ldapConfigurationActive

Can't find ldap user

Even though admin interface "verify user" works:

php occ ldap:check-user foo

Cannot check user existence, because disabled LDAP configurations are present.

Admin interface, under LDAP / AD integration ->Advanced "Configuration active"

 php occ ldap:check-user foo --force

LDAP Operations error. Anonymous bind might not be allowed.

Save password and try again

getpwuid: couldn't determine user name from uid 4294967295, you probably need to modify the User directive
