The same problem with apache2-cgi-bin-printenv-2.2.17-alt0.M51.1 .

+++ This bug was initially created as a clone of Bug #25032 +++

apache2-cgi-bin-test-cgi-2.2.17-alt0.M51.1

An upgrade of some packages from branch 5.1 (openssl, actually) caused the upgrade of some apache packages. The postinstall script of apache2-cgi-bin-test-cgi-2.2.17-alt0.M51.1 makes use of a directory that however hasn't been installed by APT.

Manual repetition of the postinstall script:

# control cgi-bin_test-cgi symlink_root_noexec
ln: creating symbolic link `/var/www/cgi-bin/test-cgi': No such file or directory
chown: cannot access `/var/www/cgi-bin/test-cgi': No such file or directory
# l /var/www/

Perhaps, the package should require the directory it wants, i.e., a newer package that contains that directory. Otherwise the upgrade from branch 4.1 isn't smooth.
