As nobody in the non-english support forum helped I am translating my problem:

I updated to nc23 but the problem existed for a while I assume.

When I try to activate talk I get:  
An exception occurred while executing a query: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away  
there are some errors in the mysql log, most important should be:  
2022-01-24 12:03:46 0x7f669009b700 InnoDB: Assertion failure in file /build/mariadb-10.3-ym4QNJ/mariadb-10.3-10.3.32/storage/innobase/dict/dict0mem.cc line 143  
InnoDB: Failing assertion: dict\_tf2\_is\_valid(flags, flags2)  
InnoDB: We intentionally generate a memory trap.  
and  
Server version: 10.3.32-MariaDB-0ubuntu0.20.04.1  
and  
Trying to get some variables.  
Some pointers may be invalid and cause the dump to abort.  
Query (0x7f666809ef80): ALTER TABLE oc\_talk\_rooms ADD server\_url VARCHAR(255) DEFAULT NULL, ADD default\_permissions INT DEFAULT 0 NOT NULL, ADD call\_permissions INT DEFAULT 0 NOT NULL

I think the problem is already explained here, unfortunately I do not understand whether there is already a solution to my problem there  
[https://jira.mariadb.org/browse/MDEV-17989?jql=text%20~%20"Failing%20assertion%3A%20dict\_tf2\_is\_valid(flags%2C%20flags2)"](https://jira.mariadb.org/browse/MDEV-17989?jql=text%20~%20%22Failing%20assertion%3A%20dict_tf2_is_valid(flags%2C%20flags2)%22)

I uninstalled talk multiple times now and also restarted the server.

Hey Mops.

I recently ran into a similar problem. It seems to be related to inconsistent InnoDB tables. I described a solution here:

[https://github.com/nextcloud/server/issues/31285#issuecomment-1057408996](https://github.com/nextcloud/server/issues/31285#issuecomment-1057408996)

Hope that helps.
