This caused problems with some installer packages like libdvd-pkg which install a locally built package in such a hook. To reduce the impact, a fix has been applied in 1.7.0 which exports the DPKG_FRONTEND_LOCKED variable when running those scripts, allowing dpkg to be run from those scripts. [Test case] Make sure that the test-frontend-lock test run by autopkgtest succeeds. This checks that: (1) the variable is correctly exported to those scripts (2) the frontend lock is still held (3) dpkg can be run from the post-invoke script [Regression potential] Depending on the script (for example, if the script starts a daemon manually or something like that), DPKG_FRONTEND_LOCKED might leak to other processes which might survive the apt call and thus revert surviving process to not using frontend locking. [Other info] This fix is for backwards compatibility only. Starting with the dd cycle, it will be dropped for the Pre-Install-Pkgs and Pre-Invoke scripts. Potentially for post-invoke as well, if we find a better solution for it.
