Is there any way to avoid this warning? It is especially annoying in the TUI, since it creates a pop-up that needs to be dismissed. Please note that apt-get does not show this warning, so it doesn't seem to be an essential feature of the fetching of the change log. > So > > >As user: > > > >% aptitude changelog apt > /dev/null > >W: chmod 0700 of directory /var/lib/apt/lists/partial failed - > >SetupAPTPartialDirectory (1: Operation not permitted) > >W: chmod 0700 of directory /var/cache/apt/archives/partial failed - > >SetupAPTPartialDirectory (1: Operation not permitted) > > I suppose that as normal user, libapt doesn't do the check mentioned > above (perhaps because uid!=root and assumes that it's "_apt"). > > In my system, both dirs' permissions are 700 and owned by _apt:root, it > doesn't emit any error and changelog works fine, no warnings. On my system, these dirs have the same permission and owners, but I do get the warnings: [matijs@walnut] ls -ld /var/lib/apt/lists/partial drwx------ 2 _apt root 32768 Feb 9 17:23 /var/lib/apt/lists/partial [matijs@walnut] ls -ld /var/cache/apt/archives/partial drwx------ 2 _apt root 4096 Feb 9 14:44 /var/cache/apt/archives/partial [matijs@walnut] aptitude changelog apt > /dev/null W: chmod 0700 of directory /var/lib/apt/lists/partial failed - SetupAPTPartialDirectory (1: Operation not permitted) W: chmod 0700 of directory /var/cache/apt/archives/partial failed - SetupAPTPartialDirectory (1: Operation not permitted) It seems something else must be wrong.
