Hi,

but no work for me
when I do:

dpkg --configure --pending

i have this message:

I don’t know how to fix, to restart the slapd service I have to replace the slapd.conf file with slapd.conf.last

Hi,

I am unsure about your issue. Can you start the LDAP-daemon manually? systemctl start slapd?
Does this work?

If not, try to configure your system until you have a running slapd. Then the apt command should work again.

if i start manually without change slapd.conf, i have this message:

systemctl start slapd
Job for slapd.service failed because the control process exited with error code.
See "systemctl status slapd.service" and "journalctl -xe" for details.

Ok, looks like you have a schema issue.

/etc/ldap/slapd.conf: line 143:

Try to comment the faulty line in slapd.conf* and get slapd to start. Once started, install Guacamole again.

/KNEBB

I followed your instructions, but I still have the same problem

6

I doubt you still have exact the same error message when trying to start!

7

there is no error when I install GUACAMOLE but when I want to fix the problem of corrupted packages I have that

dpkg --configure -a

and for restart sladp i must be change the

slapd.conf

I remove Guacamole. I removed everything related to Guacamole, plus “ucsAttr1 and ucsAttr2” from the file

/etc/univention/base.conf

and now all is Ok
