Hi there!
Finally I've had this problem resolved. I had to purge several packages and then the problem was fixed. But before you follow the steps below I think it's wise to first try the very simple solution proposed by
lalpi earlier in this thread. And also, please read through all the steps before getting started. You've been warned! All known and unknown disclaimers are valid.
root@zaq:/# sudo apt-get purge zentyal-sogoThen I had to purge
apache2 and all its dependencies, as reported by
apt-get "The following packages were automatically installed and are no longer required". But instead of using
autoremove i purged them to also have configuration files removed.
root@zaq:/# sudo apt-get purge apache2 apache2-bin apache2-data libaprutil1-dbd-sqlite3 libaprutil1-ldap liblua5.1-0 libstring-random-perlFor some reason
apache's config files in
/etc/apache2 was not removed during the purge so I manually had to remove it, or rather rename the folder.
root@zaq:/# mv /etc/apache2 /etc/apache2.oldI continued and purged
sogo as well. It might be that this is what I should have done from the very beginning but hey, I'm only human...
root@zaq:/# sudo apt-get purge sogoThen I continued with re-installing zentyal-sogo .
apt-get took care of all dependencies and installed
apache2 together with a bunch of other packages.
root@zaq:/# sudo apt-get install zentyal-sogo
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following additional packages will be installed:
apache2 apache2-bin apache2-data libaprutil1-dbd-sqlite3 libaprutil1-ldap liblua5.1-0 libstring-random-perl sogo sogo-activesync
Suggested packages:
apache2-doc apache2-suexec-pristine | apache2-suexec-custom ufw
The following NEW packages will be installed
apache2 apache2-bin apache2-data libaprutil1-dbd-sqlite3 libaprutil1-ldap liblua5.1-0 libstring-random-perl sogo sogo-activesync zentyal-sogo
0 to upgrade, 10 to newly install, 0 to remove and 0 not to upgrade. There was some error messages reported from
apache during installation but I ignored those. I opened Zentyal's web interface and then activated the package. After that everything was up and running again!
Case closed!
