Nextcloud Update Error for 18.0.4

šŸš§ Installation
21

Turns out I have different messages when I try to connect with my phone (cannot write into ā€œappsā€ directory) or desktop (maintenance mode)

and from what I can tell/do, thatā€™s not a cache issueā€¦ I really donā€™t understand this

22

Hmm

Some modules are missing :slight_smile:

Activate them with :
a2enmod headers
a2enmod env
a2enmod dir
a2enmod mime
a2enmod rewrite
a2enmod php

and service apache2 restart
And let me know if the problem persists

all but php say ā€œModule xyz already enabledā€, php doesnā€™t exist apparently

thanks for your time already thoughā€¦

/e: specifying php 7.3 did work though. (already enabled)

no change

/e: not allowed to answer ("new users temporarily limited to 3 answers in a single thread), hopefully you can see this:

should ā„¢ be default, except for:

<Directory /var/www/> Options Indexes FollowSymLinks AllowOverride All Require all granted </Directory>

where I changed from AllowOverride None to AllowOverride All (to fix an issue)

/e3:

cat /etc/apache2/sites-enabled/nextcloud.conf
<VirtualHost *:80>
ServerAdmin admin@example.com
DocumentRoot /var/www/html/nextcloud/
ServerName nextcloud.example.com

 Alias /nextcloud "/var/www/html/nextcloud/"

 <Directory /var/www/html/nextcloud/>
    Options +FollowSymlinks
    AllowOverride All
    Require all granted
      <IfModule mod_dav.c>
        Dav off
      </IfModule>
    SetEnv HOME /var/www/html/nextcloud
    SetEnv HTTP_HOME /var/www/html/nextcloud
 </Directory>

 ErrorLog ${APACHE_LOG_DIR}/error.log
 CustomLog ${APACHE_LOG_DIR}/access.log combined

/e4: holy crap, this got it, thanks for pointing out where to look!
You were right, I just needed to disable maintenance mode (and after that fix the owner of the files with the command chown www-data:www-data you already mentioned), just in the right place:

SetEnv HOME /var/www/html/nextcloud

For some reason (propably an attempt from way earlier) I had a very old nextcloud instance in /var/www/nextcloud, but the one that I was using (that apache knows about) is in /var/www/html/nextcloud.

Which explains why I ā€œfell downā€ in version from 17 to 14, and of course why changing maintenance mode didnā€™t do anything.
I didnā€™t change anything in the actual instance I was working with.

Holy crap, thanks for your help.
Sorry for wasting your time.
That was a weird one for me, although of course entirely my fault.

I donā€™t remember putting a nextcloud thereā€¦ But I apparently did.

Thank you, Iā€™m back to working.
(Also kinda sorry for hijacking the thread)
Solved for me as well
