Uninstalling Etherpad for Upgrade

UCS - Univention Corporate Server
,
#1

Hi,

i have already updates my UCS Master to 4.2 and i want now to upgrade as well my slave which is still on 4.1.4.
Therefore i need to uninstall the etherpad app. It is currently installed in version 1.6.0, but i have the feeling that there is just the app-center entry available, but no files anymore (why ever). The app center shows me that there is an update available. If i try to uninstall it, i get the following error message:

Ein Fehler ist aufgetreten: No container found. Unable to backup

When i then log out and log in again, it tells me that there are not execute join scripts:
51etherpad-lite-uninstall
I execute this and it tells me that i was executed succesfully.
Unfortunately, the App is still listed in the App Center of the slave. In the app center of the master it is not listed.
As i cannot uninstall the app, i cannot upgrade my system.

Kind Regards,

Tobias Lorentz

Hi,

Has no one an idea?
This is blocking me from upgrading.

Hi,

first of all, you should be able to update to UCS 4.2 with Etherpad 1.6.0 installed. What is the error message of the “Software update” module (or univention-upgrade if you are working with the command line)?

Anyway, your Etherpad installation seems to be broken. On the Slave, is the Docker Container running?

docker ps -a

What does

ucr search --brief appcenter/apps/etherpad-lite

say? If your Slave’s App Center module says it is installed but your Master’s module does not, there is something wrong with the registration of the App (either “false positive” or “false negative”). But I think we should be able to work that out.

Hi Dirk,

first, thank you very much for your help.
When i execute univention-upgrade i get the following result:

root@ucs2:/home/tobias# univention-upgrade

Starting univention-upgrade. Current UCS version is 4.1-4 errata479

docker seems to run:

The command ucr search --brief appcenter/apps/etherpad-lite returns nothing on the slave as well as on the master.

Seems to be very old, I think that was before UCS 4.1 was released with docker. So you should check this on the master:

ucr search --brief repository/online/component

Hi,

the output of this command on the master is:

Hi,

okay, it seems that Etherpad 1.6 was not installed on your DC Slave. Instead it was / is 1.5.6-2. The one notable difference is that the first is a Docker App, the latter is not. Upgrading from one App to another is tricky most of the times. Therefore, this Article exists: http://wiki.univention.de/index.php?title=Etherpad-lite_App_Migration

But this is probably not working here as the App registration is still broken.

What does

univention-app info

and

ucr search --brief repository/online/component

on your DC Slave say?

Did you actually use Etherpad or was it just installed for testing? Do we need to look into backing up some data or can we just ignore it?

Kind regards,
Dirk Wiesenthal

On your DC Master, what does the following give you?

udm appcenter/app list | grep DN:

I had just installed etherpad for testing, so there is no need for backup up something.

Hi,

somehow the App is registered, but not installed. This may be caused by some software update that automatically removed the package “etherpad-lite” (e.g., due to some conflicts in the package list). The App Center was not involved in uninstalling the App and thus could not unregister it properly. If you search your /var/log/univention/updater.log* files, you may find the answer.

Anyway, to fix it, you should only need to “repair” the installation state:

univention-app register etherpad-lite=1.5.6-2

on the DC Slave should erase any leftovers. After that, the update to UCS 4.2 should be possible as there is not more etherpad-Repository in the way.

Kind regards,
Dirk Wiesenthal
