I recently autoremoved my old unused kernels. At the end of the process it output this message:

W: Duplicate sources.list entry http://dl.google.com/linux/talkplugin/deb/ stable/main amd64 Packages (/var/lib/apt/lists/dl.google.com_linux_talkplugin_deb_dists_stable_main_binary-amd64_Packages)
W: Duplicate sources.list entry http://dl.google.com/linux/talkplugin/deb/ stable/main i386 Packages (/var/lib/apt/lists/dl.google.com_linux_talkplugin_deb_dists_stable_main_binary-i386_Packages)
W: You may want to run apt-get update to correct these problems

So I ran sudo apt-get update but got the same message at the end of that. So I ran it again and still got the same message.

What should I do now?

  • Post your /etc/apt/sources.list in your question AND the duplicate entry. – A.B. Apr 24 '15 at 16:18
  • I see two daniel_pavel-solaar-trusty.list in that list. (Also next time, instead of making a list, just post the output of ls -1 /etc/apt/sources.list.d) – muru Apr 26 '15 at 17:45

You have duplication in your sources lists. This usually occurs if you accidentally add the same repository twice. check out /etc/apt/sources.list and the contents of /etc/apt/sources.list.d/ and check for duplicates.

  • I don't see any duplicates in either. I'll add both to the question though incase I'm missing something, which is likely. – hal Apr 24 '15 at 16:28
