Summary of the issue you are facing:
My .htaccess file has failed a “code integrity” check
From my Admin Settings Overview page:
Code integrity
Some files have not passed the integrity check. List of invalid files… Rescan…
And when I hit the “List of invalid files”-option, i get:
Raw output
==========
Array
(
[core] => Array
(
[INVALID_HASH] => Array
(
[.htaccess] => Array
(
[expected] => a2d827c...
[current] => 17477516e...
)
)
)
)
Steps to replicate it (hint: details matter!):
The problem appeared just before I updated NC from v 34.0.5 to 35.0.2 (my current version) and I thought I had successfully dealt with it via the second solution below:
Solutions attempted:
- Tried ernolf’s “nc-integrity-fix”-script, as detailed here:
Didn’t help:
azed@azed-byte:~$ nc-integrity-fix
This app is affected:
core
The hash of this file in [core] is invalid:
.htaccess
Q: Do you want to replace this invalid file with a file downloaded from github
for your version?
Make your choice: ([y]es or [n]o) [yes]: y
download of '.htaccess' failed. You must check this one yourself
- Tried to replace my .htaccess-file for an “uncorrupted” one, as detailed here:
https://help.nextcloud.com/t/code-integrity-check-problems/1895/2
Downloaded the appropriate (v. 34.0.5) nextcloud files from here:
https://nextcloud.com/changelog/#latest34
-- Extracted the .htaccess file
-- Checked permissions matched:
OLD
azed@azed-byte:~$ ls -l /var/www/nextcloud/.htaccess
-rw-r--r-- 1 www-data www-data 7940 Oct 17 17:02 /var/www/nextcloud/.htaccess
NEW
azed@azed-byte:~$ ls -l /home/azed/Downloads/Nextcloud/nextcloud-34.0.5/.htaccess
-rw-r--r-- 1 azed azed 6677 Oct 15 09:17 /home/azed/Downloads/Nextcloud/nextcloud-34.0.5/.htaccess
-- Fixed file ownership:
sudo chown www-data:www-data /home/azed/Downloads/Nextcloud/nextcloud-34.0.5/.htaccess
azed@azed-byte:~$ ls -l /home/azed/Downloads/Nextcloud/nextcloud-34.0.5/.htaccess
-rw-r--r-- 1 www-data www-data 7940 Oct 24 15:44 /home/azed/Downloads/Nextcloud/nextcloud-34.0.5/.htaccess
-- Replaced the old .htaccess-file with the new
azed@azed-byte:~$ sudo mv /home/azed/Downloads/Nextcloud/nextcloud-34.0.5/.htaccess /var/www/nextcloud/.htaccess
-- Reloaded apache2
azed@azed-byte:~$ sudo systemctl reload apache2
When I re-loaded the Administrator Settings Overview page, the code integrity warning had disappeared (hoorah!)
However, after the update to NC v 35.0.2, it re-appeared (boo!)
- I also tried this suggested fool-the-system work-around:
see also here:
https://help.nextcloud.com/t/integrity-check-failed-htaccess-file-invalid/163774/2
Did as suggested:
-- Edited end of /var/www/nextcloud/config/config.php
From:
'mail_smtpport' => '465',
'mail_smtpauth' => 1,
'mail_smtpname' => ``'``withheld',
'mail_smtppassword' => 'withheld',
'theme' => '',
'loglevel' => 2,
'htaccess.RewriteBase' => '/',
'serverid' => '0',
);
To:
'mail_smtpport' => '465',
'mail_smtpauth' => 1,
'mail_smtpname' => 'withheld',
'mail_smtppassword' => 'withheld',
'theme' => '',
'loglevel' => 2,
'htaccess.RewriteBase' => '/',
'serverid' => '0',
'integrity.check.disabled' => true,
);
-- Saved file
-- Re-loaded Admin Settings Overview page - code-integrity error had vanished
-- Removed the line " ‘integrity.check.disabled’ => true, " from /var/www/nextcloud/config/config.php
-- Logged out and in again: code integrity problem was back (sigh)
QUESTIONS:
- Why am I getting this error
- How do I get rid of it (permanently)?
Log entries
Nextcloud
Please provide the log entries from your Nextcloud log that are generated during the time of problem (via the Copy raw option from Administration settings->Logging screen or from your nextcloud.log located in your data directory). Feel free to use a pastebin/gist service if necessary.
Here are a couple of entries from the Administrator Settings Overview “Logging”-page from the time of my update to v35.0.2. They don’t appear to me to be very useful:

Web Browser
If the problem is related to the Web interface, open your browser inspector Console and Network tabs while refreshing (reloading) and reproducing the problem. Provide any relevant output/errors here that appear.
N/A
Web server / Reverse Proxy
The output of your Apache/nginx/system log in /var/log/____:
Couldn’t see anything relevant
Configuration
Nextcloud
The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
