Resolved Apache not running after Dist-Upgrade to Ubuntu 16.04

[jradzuweit]

Hi,
I have done a distribution upgradde from Ubuntu 14.04 to 16.04, it worked so far without major problerms except to things.

1. the file /etc/os-release still says it is a Ubuntu 14.04 instead of 16.04. The apt-get files say it has all repos switched to xenial aka Ubuntu 16.04.

2. This is a more serious problem, after the upgrade the apache does not start and the command systemctl says:

Okt 02 12:21:55 vega.radzuweit.eu apache2[3112]: * The apache2 configtest failed.
Okt 02 12:21:55 vega.radzuweit.eu apache2[3112]: Output of config test was:
Okt 02 12:21:55 vega.radzuweit.eu apache2[3112]: AH00526: Syntax error on line 240 of /etc/apache2/plesk.conf.d/ip_default/radzuweit.eu.conf:
Okt 02 12:21:55 vega.radzuweit.eu apache2[3112]: Invalid command 'DirectoryIndex', perhaps misspelled or defined by a module not included in the server configuration
Okt 02 12:21:55 vega.radzuweit.eu apache2[3112]: Action 'configtest' failed.

Any idea what to do next? The apache files where not changed and the DirectoryIndex is a common config directive in apache.
I already searched the KB and the forum here but nothing suitable found so far..

Thanx for any suggestion
Jürgen

Make sure that dir module is enabled in Tools&Settings-> Apache Web Server

does not help much, because the plesk gui is not accessable, while apache is not running ;-)

... it seems that during the upgrade a link gets lost. Here a solution to get this fixed:

1. go to /etc/apache2/mods-enabled and check if a link to ../mods-available/dir.conf and ../mods-available/dir.load exists
2. if not create links with

>ln -s ../mods-available/dir.conf
>ln -s ../mods-available/dir.load
​

Apache is now running
