Getting help
In order to help you as efficiently (and quickly!) as possible, please fill in as much of the below requested information as you can.
Before clicking submit: Please check if your query is already addressed via the following resources:
- Official documentation (searchable and regularly updated)
- How to topics and FAQs
- Forum search
(Utilizing these existing resources is typically faster. It also helps reduce the load on our generous volunteers while elevating the signal to noise ratio of the forums otherwise arising from the same queries being posted repeatedly).
Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can. 
The Basics
- Nextcloud Server version (e.g., 29.x.x):
- Nextcloud Hub 10 (31.0.5)
- Operating system and version (e.g., Ubuntu 24.04):
- Linux version 5.14.0-570.52.1.el9_6.x86_64 (RedHat 9.6 - Plow)
- Web server and version (e.g, Apache 2.4.25):
- Apache 2.4.62
- Reverse proxy and version _(e.g. nginx 1.27.2)
- don’t know
- PHP version (e.g, 8.3):
- 8.2.29
- Is this the first time you’ve seen this error? (Yes / No):
yes
- When did this problem seem to first start?
after update to 31.0.10
- Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
manually from archiv, following thisguide
- Are you using CloudfIare, mod_security, or similar? (Yes / No)
no
Summary of the issue you are facing:
I upgraded Nextcloud manually via CLI from version 31.0.5 to 31.0.10, I followed this guide:
link
At the end I got message “Update successful”, but after starting apache i’m not able to run web UI → i got error:
“Error
Cannot write into “config” directory! This can usually be fixed by giving the web server write access to the config directory. But, if you prefer to keep config.php file read only, set the option “config_is_read_only” to true in it. See link”
I checked ACLs in Nextcloud directory, Config directory as well. Apache user is owner of these directories and should be able to write inside.
ACL of dir. /var/www/html/nextcloud/config :
drwxr-x—. (750)
I compared to the old Config dir. (before upgrade) - it was:
drwxr-xr-x. (755)
There is general recommendation that httpd should run under apache user. I found that my apache is running under root. I maybe made some mistake during initial installation, but even when I change ACL to the 755, it doesn’t help, error still the same.
Then I found this explanation: https://askubuntu.com/questions/694036/apache-as-non-root (so it should be fine for me ?). I’m confused.
I checked which user is defined for httpd service in /etc/httpd/conf/httpd.conf:
User apache
Group apache
I verified parent and child processes
ps -ef | grep -i httpd | awk ‘{print $1}’
root
apache
apache
apache
apache
apache
Could you please help to find the misconfig and get it running ?
Thank you very much.
