Duplicate sources.list entry in ubuntu 12.04

[yrohinkumar]

I know it's a noob question...but it is bothering me for a while...I'm sure I'm missing something here...

I keep getting this every time I try to update...:mad:

W: Duplicate sources.list entry http://archive.canonical.com/ubuntu/ precise/partner i386 Packages (/var/lib/apt/lists/archive.canonical.com_ubuntu_dists_precise_partner _binary-i386_Packages)
W: You may want to run apt-get update to correct these problems

I tried removing that file /var/lib/apt/lists/archive.canonical.com_ubuntu_dists_precise_partner _binary-i386_Packages

looked into sources.list to remove the mentioned duplicate entry...but I couldn't find one...!!!

Any ideas???

Use crtl-f to search for the extra in.


sudo gedit /etc/apt/sources.list

Thanks for the quick reply...

I presume u were talking about this entry "deb http://extras.ubuntu.com/ubuntu precise main" which was the only one containing the word 'extra'... I disabled it...but with no luck...the error persists...

btw I noticed 'sources.list~' file and 'sources.list.d/' in the same folder...the entries in those are counted too???

Only you will know the extra, run a update in the terminal and post all of it, Extra will not be in the actual list it is saying you have an extra in the terminal as a communication.

Also post this

cat /etc/apt/sources.list

This is what I have... (Sorry for the mess...I've been updating distros since long time ago and have problem managing huge list of repos...)

Told u it is a mess :)

[wilee-nilee]

open this again.

sudo gedit /etc/apt/sources.list

Hit crtl-f and put in this in to search.

deb http://archive.canonical.com/ubuntu precise partner

This I think is the double entry

[yrohinkumar]

Thanks a lot for seeing the problem through the end... it worked...the error message was kinda misleading...but thanks again for patiently looking this through... :)

No problem it took me a minute to figure it out, I just did the same search with the whole line and used the back space and removed one letter at a time.

Thnx for this fix, it worked. I had the same problem and removed these 2 double entries:

deb http://archive.canonical.com/ubuntu precise partner
deb-src http://archive.canonical.com/ubuntu precise partner

[terdegstra]

S="/etc/apt/sources.list" ; S2="$S ${S}.d/*.list" ; grep -b "^deb`cat $S2 | grep -i "^deb[[:space:]]http" | sort | uniq -dc | sed -e 's;[[:space:]]\+[[:digit:]]\+[[:space:]]\+deb\(.\+$\);\1;g'`$" $S2

[lcniuren33]

Thanks a lot, I have the same problem and solved following your method~:guitar:

[Alex.Pi]

hi,
I have the same problem but I do not have this string in the file, so I do not know what to remove.

sorry for confusion, I have found it and all works.
Thank you.
