I'm attempting to do the equivalent of holding a package via /etc/apt/preferences.d/something.pref in 16.04, and the behaviour seems to have changed from 14.04.

Given some package foo that has an installed version like, in 14.04, the following stanza will prevent apt-get upgrade from upgrading foo:

Package: foo
Pin: version 1
Pin-Priority: 501

You'll note that version 1 does not in fact match anything close the the actual package version.

The same stanza, in 16.04, does not appear to have any effect. Is there a way to do this? I'm aware of apt-mark hold foo, but for various internal reasons that's not as good a solution if using a pin is possible.

The only difference I observe is that when running apt-cache policy foo, on 14.04 I see output that starts like this:

  Package pin: (not found)

But on 16.04 the Package pin: (not found) is not present.

Running a bare apt-cache policy also includes lines like the following on 14.04

Pinned packages:
     foo -> (not found)

while on 16.04 the Pinned packages: section is entirely empty.

  • See my Q&A - it uses syntax that working for me on Ubuntu 16.04 LTS. – N0rbert Jul 4 '18 at 9:00
