Revert "Temporarily downgrade key assertions to "soon worthless""
We temporarily downgraded the errors to warnings to give the
launchpad PPAs time to be fixed, but warnings are not safe:
Untrusted keys could be hiding on your system, but just not
used at the moment. Hence revert this so we get the errors we
want.
This reverts commit 66998ed3d299bede651ad40368bdb270f5f5b0f9.
The Graphviz change adapted only the msgstrs in the po files, which
fuzzied all translations the moment the msgids were updated by the
merge while forgetting fr.po and pl.po and in the VCG change the
msgstr in the ja.po was missed.
This commit "just" unfuzzies the strings (and fixes the missed ones)
so the translators don't have to as intended in the commits.
Ignore umask of leftover diff_Index in failed pdiff test
We don't store .diff_Index files anymore and so libapt cares even less
about these purposefully leftover files from the testcases than it did
previously. On a successful apt run they would just be deleted, but as
we are testing a failed run they are not touched at all.
Testing the file access bits then means we check with whatever umask
they were created which might very well be different to what apt decides
these files to have if it had touched them, so for this test we just
delete them. For the other case we set it completely wrong just in case,
but they will (hopefully) be non-existent anyhow as tested first.
Avoid subshell hiding failure report from testfilestats
We remove the working directory from the found file names as these paths
could contain a lot of funny characters confusing the for loop like
spaces… we just readd it later in the actual calls to be safe.
