Ubuntu 19.04 Domain Join

UCS - Univention Corporate Server
#1

Hi,

at the moment, if I use this command on 19.04:

add-apt-repository ppa:univention-dev/ppa

I get this answer:

E: The repository 'http://ppa.launchpad.net/univention-dev/ppa/ubuntu disco Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

If installed on 18.10 and then upgraded, the client is still in the domain, but it takes much longer to do so.

I need this quite urgently for a customer who wants to join more than 200 clients.

Can this be fixed on short notice?

Cheers,
Roland.

Hi Roland,
at the moment there is no repository for 19.04 (Disco Dingo). Latest repo is for 18.10 (Cosmic Cuttlefish).

Hi,
yes, I know that this is the problem.

I just tried to install it manually and I guess the problem is that the package auth-client-config is not available in Disco Dingo.
Don’t know how to work around that, though.

EDIT: I just installed the bionic version of auth-client-config and it works now.
It’s a bit tricky though.

Here the necessary steps:
Copy the python join script from another machine to the 19.04 client:
/usr/share/univention_domain_join/cli.py
Also create the symbol link:
/usr/sbin/univention-domain-join-cli -> /usr/share/univention_domain_join/cli.py

Install the packages:
apt install sssd libnss-sss libpam-sss libsss-sudo heimdal-clients ntpdate sshpass python python-pip

Zip the folder:
/usr/lib/python2.7/dist-packages/univention_domain_join
on a working machine and copy it over to 19.04. Unzip it.

Install the other necessary python packages:
pip install IPy
pip install dnspython
pip install netifaces

And finally download and install the auth-client-config from Bionic Beaver:
wget http://de.archive.ubuntu.com/ubuntu/pool/universe/a/auth-client-config/auth-client-config_0.9ubuntu1_all.deb
dpkg -i auth-client-config_0.9ubuntu1_all.deb

Then the join works.

I need to script all that stuff, so does anyone know a simpler solution?

Cheers,
Roland.

Hi,

I’d recommend to create a feature request like https://forge.univention.org/bugzilla/show_bug.cgi?id=48114 but for 19.04.
In case you customer has a valid subscription for UCS domain service you should also contact Univention Sales and notify them.
BTW: Is there any technical reason for this customer to use one of the quickly changing releases instead of LTS?

cheers,
Dirk

Hi,
thanks.
Seems like the auth-client-config problem was already there for 18.10, so Univention added it to the PPA.
Therefore I guess it’s no problem to add 19.04

My customer has a valid subscription, of course :slight_smile:

He had big problems with printers, which are solved in 19.04
There were other issues, too - but I don’t know the details.

Here’s the “Bug” Report:
https://forge.univention.org/bugzilla/show_bug.cgi?id=49789

Cheers,
Roland.
