Trouble with migrating OTRS 3.0.4

[MHz]

I am migrating OTRS ITSM 3.0.4 to another server. So Icopied my configs, and database and ofcourse dowloaded OTRS 3.0.4. Everything works fine, accept the package manager, it returns the following error:

ERROR: Need write permission in OTRS home
Try: $OTRS_HOME/bin/otrs.SetPermissions.pl !!!

I did already use that with otrs user/group otrs and http user/group www-data (Im on the latest Ubuntu x64 LTS). I've read somewhere that in version 2, securemode was active by default, So I checked to see if securemode was active by default on 3.0.4, but it wasnt. Any ideas what might be wrong?

check the owner of the /opt/otrs directory

[MHz]

The owner is root (group and user) should www-data be owner? My otrs user is 'otrs'.

[jojo]

should be otrs as owner and www-data as group

[MHz]

It still gives me the same error. Permissions are as follows:

lrwxrwxrwx 1 otrs www-data 15 Oct 9 16:16 otrs -> /opt/otrs-3.0.4
drwxr-xr-x 8 otrs www-data 4096 Oct 10 10:02 otrs-3.0.4

[jojo]

webserver group will need write permisson on the directory also

[MHz]

Thank you! It works like a charm now. Any idea why the otrs.SetPermissions.pl did not set this permission?
