Bug#928813: libapache2-mod-jk: Jk can not find any configured worker

[Thorsten Glaser]

Package: libapache2-mod-jk
Version: 1:1.2.46-1
Followup-For: Bug #928813
Control: severity -1 serious
Control: notfound -1 1:1.2.46-0+deb9u1
Control: found -1 1:1.2.46-1

Indeed, this prevents libapache2-mod-jk from working at all in buster.

Comparing (“dpkg -L libapache2-mod-jk | sort | less”) betweeen stretch
(1:1.2.46-0+deb9u1) and buster (1:1.2.46-1) shows:

Note this difference:
/etc/apache2/mods-available/jk.conf (stretch) vs.
/etc/apache2/mods-available/httpd-jk.conf

In stretch, an “a2enmod jk” will enable mods-available/jk.conf
and make things work.

From reading the changelog, you wanted to “Install new httpd-jk.conf
file which follows Apache 2.4 syntax”, but the directory is wrong;
these files belong into conf-available, not mods-available.

That being said, that would require both “a2enmod jk” *and*
“a2enconf httpd-jk”, which is a UI regression against earlier,
so I’d prefer for the file to be renamed back to what it was
in stretch over moving it to another directory.
