Authentication confirm button grayed out and can't complete an admin action of any sort

Nextcloud version (eg, 20.0.5): 25.0.0
Operating system and version (eg, Ubuntu 20.04): AlmaLinux 8.6
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.54
PHP version (eg, 7.4): 8.1

The issue you are facing:
When trying to do various things in the settings, I get presented with a box asking for my password. The problem is that when I enter my password, the confirm button doesn't light up and if I hit return it tells me there was a problem. This is on a fresh install.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Download setup-nextcloud.php
  2. Upload to server
  3. Run installer and let it finish while connecting it to MySQL.
  4. Go to Apps
  5. Enable or Disable whatever apps until it prompts you for your password to verify it’s you.

Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.

None exists.

This will be fixed with 25.0.1

So then for now I’m just screwed and can’t update any of my settings? Should I go ahead and upgrade to 25.0.1 RC 1?

No, the workaround is to use the [ENTER] key

I did try that and it says authentication failed.

Then your password is wrong

My password is correct because I used a password saver, 2 to be exact just in case, and still have the problem.

I confirm that you cannot continou with enter.

also in basic settings the password box that pops up for email is the old one where as changing cron job the new one popsup.

I can also confirm that in 25 rc1 the continue
issue is solved.

Thanks. I updated to the latest release of 25.0.1 and all is good now.
