Kein pg_hba.conf-Eintrag

Dear Comunity,

since some time I’ve noticed while updating an error like:

pg.InternalError: FATAL:  kein pg_hba.conf-Eintrag für Host »192.168.x.y«, Benutzer »ucs-role$«, Datenbank »pkgdb«, SSL an

actually - I on all ucs machines. On every system the output looks like this:

root@ucs-role:~# univention-pkgdb-scan
Traceback (most recent call last):
  File "/usr/sbin/univention-pkgdb-scan", line 37, in <module>
    univention.pkgdb.main()
  File "/usr/lib/pymodules/python2.7/univention/pkgdb.py", line 578, in main
    connection = open_database_connection(config_registry, pkgdbu=False)
  File "/usr/lib/pymodules/python2.7/univention/pkgdb.py", line 560, in open_database_connection
    connection = pgdb.connect(database=connectstring)
  File "/usr/lib/python2.7/dist-packages/pgdb.py", line 1615, in connect
    cnx = _connect(dbname, dbhost, dbport, dbopt, dbuser, dbpasswd)
pg.InternalError: FATAL:  kein pg_hba.conf-Eintrag für Host »192.168.x.y«, Benutzer »ucs-role$«, Datenbank »pkgdb«, SSL an

I followed the postgres update guide provided here and here. So there was an update from 9.1, 9.4, to 9.6.

Seaching the forum only got me issues that are 10 years old. So I thought I just ask again as my knowledge of postgresql is very limited.

Is there an easy fix for this?

Best,
Bernd

Hi,

yes there is a fix available. Please check here.

Hi,

thank you @Christian_Voelker. Wonder why my search didn’t find this… But I’ve missed one point in my description of the error. It seams like the »pkgdb« database vanished from all systems:

root@ucs-master:/etc# univention-pkgdb-scan --db-server 'master.domain.com' --add 'ucs-slave$'
Traceback (most recent call last):
  File "/usr/sbin/univention-pkgdb-scan", line 37, in <module>
    univention.pkgdb.main()
  File "/usr/lib/pymodules/python2.7/univention/pkgdb.py", line 576, in main
    connection = open_database_connection(config_registry, pkgdbu=True)
  File "/usr/lib/pymodules/python2.7/univention/pkgdb.py", line 560, in open_database_connection
    connection = pgdb.connect(database=connectstring)
  File "/usr/lib/python2.7/dist-packages/pgdb.py", line 1615, in connect
    cnx = _connect(dbname, dbhost, dbport, dbopt, dbuser, dbpasswd)
pg.InternalError: FATAL:  Datenbank »pkgdb« existiert nicht

How do I create this database? The software-installation-monitor is installed on master and backup.

Thank you for helping out,
Bernd

There should be two join scripts related (I am currently unsure about correct naming please check!):

40univention-postgresql
50univention-pkgdb

They should be located under /usr/lib/univention-install but might be named slightly different. So just run these scripts again with
univention-run-join-scripts 40univention-postgresql,50univention-pkgdb

It should create the missing database.

I’ve tried this yesterday through UMC (the old threads…) but it didn’t work - same error:

Just a question:

Do you use the package database?

How about uninstalling it? And, if used, reinstall. Do you have the correct version of PostgreSQL installed? There are several topics in the forum with detailed steps how to upgrade to the latest version (yes, has to be done manually!).

/CV

That was more than one question… :wink:

So yes the package was installed. I uninstalled it. I’ve tried to reinstall it - but it fails.
As far as I can see 9.6 is installed.

root@ucs-master:/etc# ps aux | grep postgres

I followed this.

Is the database »pkgdb« needed for anything else? If not - I will just leave it as it is. I’m not working much with the app.

Thanks for helping out
Bernd
