I compared sources.list from normal Ubuntu 17.10 installation and from MATE. They differ by 4 rows:
--- /etc/apt/sources.list +++ /media/mate1710/724aac41-cc95-44d2-993b-32b544ab9022/etc/apt/sources.list @@ -1,7 +1,4 @@ -# deb cdrom:[Ubuntu-MATE 17.10 _Artful Aardvark_ - Release i386 (20171018)]/ artful main multiverse restricted universe -deb http://archive.ubuntu.com/ubuntu/ artful main restricted universe multiverse -deb http://security.ubuntu.com/ubuntu/ artful-security main restricted universe multiverse -deb http://archive.ubuntu.com/ubuntu/ artful-updates main restricted universe multiverse +#deb cdrom:[Ubuntu 17.10 _Artful Aardvark_ - Release amd64 (20171018)]/ artful main restricted # See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to # newer versions of the distribution. So it seems to be MATE community fault. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1697120 Title: artful's apt-file and aptitude complains about Ubuntu sources.list Status in ubuntu-mate: New Status in apt package in Ubuntu: Fix Released Status in apt source package in Zesty: Fix Committed Status in apt package in Debian: Fix Released Bug description: [Impact] apt-file is now difficult to use with about a dozen warnings like this: W: Target Contents-deb-legacy (Contents-amd64) is configured multiple times in /etc/apt/sources.list:6 and /etc/apt/sources.list:17 For reference, this is line 6: deb http://us.archive.ubuntu.com/ubuntu/ artful main restricted And this is line 17: deb http://us.archive.ubuntu.com/ubuntu/ artful universe This is how Ubuntu's default sources.list has been structured since the beginning? (or at least more than a decade). What I expect ------------- The warning isn't specific enough. Lines 6 and 17 are not actually duplicates. The warning could be removed or fixed so that it doesn't complain about non-duplicates. Or the warning could be disabled on Ubuntu. See also -------- LP: #1579372 [Test case] Install apt-file and update, make sure that the warnings are gone. [Regression potential] Warnings about duplicate index targets containing "legacy" in their configured name are not shown anymore, thus it's harder to "fix" servers. But apart from that, which was the goal, I don't see any.
