Apt Configuration File - Invalid Filename Extension #3
Description
When running apt-get update, apt complains about a configuration file containing an invalid filename extension. This is caused by 30autoproxy.uoit (and possibly 30autoproxy.uoit-orig) being present in the /etc/apt/apt.conf.d directory.
N: Ignoring file '30autoproxy.uoit' in directory '/etc/apt/apt.conf.d/' as it has an invalid filename extension.
This is caused by the diversion of apt configuration files by config-package-dev. Unfortunately there does not seem to be a way to continue using this system and not receiving this warning. The bug was supposedly fixed in apt (LP #631770) but this not the case; it only fixes invalid filename extension warnings for files in /etc/apt/sources.list.d/.
One option would be to manually use dpkg-divert in postinst and prerm but this bug is harmless so it may be worth waiting for upstream to fix it.
