It seemed that simply deleting the opera-stable.list file might cause problems, if some other program ever went looking for it, or possibly the deleted file would just be recreated. So apparently this line 52 was already doing the work of keeping Opera updated. Sure enough, line 52 said the same thing, but without the “#Opera Browser (final releases)” comment at the end. The latter line read, “deb stable non-free #Opera Browser (final releases).” I went into gedit > Edit > Preferences > Display line numbers, and then took another look at sources.list. Looking again at the error messages, they seemed to be saying that the duplication was in line 52 of sources.list and line 4 of opera-stable.list. A similar command ( sudo -i gedit /etc/apt//opera-stable.list) opened that opera file. Its first lines said, “This file makes sure that Opera Browser is kept up-to-date as part of regular system upgrades.” Then I noticed that (a) there were no repeated lines in the sources.list file and (b) the error messages all referred to Opera.Ī revised search led to a suggestion that I might want to edit the opera-stable.list file rather than sources.list.

In that session, I looked for the lines that might be repeatedly referring to the foregoing repositories (e.g., the “non-free/binary-amd64/Packages” mentioned in the first of those error messages). The first command opened a gedit (editor) session. W: Target DEP-11-icons (non-free/dep11/icons-64×64.tar) is configured multiple times in /etc/apt/sources.list:52 and /etc/apt//opera-stable.list:4Ī search led to ( 1 2) suggestions to edit the sources.list file by using these commands: sudo - i gedit / etc / apt / sources.

As described in another post, I was working in a new Xubuntu installation.
