It seems that the usermod is stripped down from all the options and doesn’t have -r. Something @MichaIng should look at.

I ran dietpi-update for a second time and it completed without any errors. I’m not sure if any of the clean up scripts was run because I was not prompted to uninstall the previous pihole dependencies?

How do I run the clean up script manually?

Probably web server and PHP are still used by other applications. At least we check for know apps like Nextcloud. In this case, no decency will be removed.

Best indicator for a successful DietPi/ Pihole migration is the availability of PiHole on port 8089

To force a new DietPi update, you can run

dietpi-update -1

What would be helpful is if you share the entire log the next time you hit the error. That way we would know at which step it stops.

I am doing the same update (on bullseye) and got the same error, at the moment I’ve used the option to use a temp shell and this is what I can add to the OP:
I already had pihole 6 installed and I was running it on a different port as 80/4433 are used by reversed proxy.
this is the on screen log:

Same here. I upgraded pi-hole on Feb. 22. after running dietpi-update.
Today I ran dietpi-update again and saw the same error message.
I simply ran dietpi-update once more without error message.

But there’s more: Outdated certificate, unbound not working . . .
I will first google a little more before posting.

Thanks for reading, Emil

we will have a look into this

That -r option was added with Bookworm it seems, hence Bullseye systems run into this. I’ll replace it with gpasswd -d www-data pihole. Only nasty that this one fails, if the user in not in the group anymore. usermod handles this more gracefully.

I just pushed this to master directly. Retrying the update should hence work now.

I would like to take this opportunity to point to our blog. Debian Bookworm has been released – DietPi Blog Maybe it’s the right time to update to Bookworm. Especially since the next Debian release Trixi will be released this summer 2025 and it will turn Bullseye into oldoldstable Debian :wink:

I ran this again and there were no errors. There were still no prompt to clean up? Is there supposed to be? I only have PiHole, Vaultwarden, and Caddy on this Pi.

Depends on software installed. Can you check

dietpi-software list | grep " =2 "
13

Ok, looks like there were more than I thought, some that I didn’t explicitly install. Is there anything I can uninstall, Lighttpd perhaps?

If not needed, removing software ID 81 and 82 should clean it.

I’ve resumed the upgrade and replaced the usermod with gpasswd -d www-data pihole and the upgrade finished successfully. However, pihole installation has changed the gui ports I’ve defined for http and https and used port 8089 for http and nothing for https.
(I had pihole 6 working on user defined ports since 80/443 were taken)
It is easy to change it back, but just wanted to mention it in case others user run into it and think pihole-web is not installed.
Thanks for the quick fix.

16

This is expected and communicated during DietPi update. As well we give the command how to change ports.

The Pi-hole v6 migration is indeed not done a second time, as the existence of the /var/www/pihole symlink is used as marker, and it has been removed on the first attempt already.

Webserver stacks cannot be removed directly. They are only a meta option for installing webserver, database and PHP, and the install status adjusts automatically based on whether this trio is installed. Hence, uninstall the webserver and PHP explicitly, if not needed:

dietpi-software uninstall 84 89

I also see nothing which depends on the MariaDB database server, unless you configured vaultwarden to use MariaDB instead of SQLite. But better be sure really nothing else uses it, and remember why it has been installed in the first place, before removing it.

I logged into the database and checked. Looked like a default install with the usual tables so I uninstalled it along with the others. Many thanks to you and @Joulinar.
