duplicate sources.list problem with only one entry in sources.list

[mmistroni]

HI all
i have upgraded to ubuntu 12.04 on my toshiba satellite
i keep on getting this exception when running apt-get update

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)

the only non commented entry in my sources.list is this line

deb http://archive.ubuntu.com/ubuntu precise main restricted universe multiverse

could anyone assist?

kind regards
marco

mmistroni; Sure !

We can help.

Post back the output -between code tags - of terminal commands:


cat -n /etc/apt/sources.list
cat /etc/apt/sources.list.d/*.list

And we will see if we can identify that duplicate entry and advise how to remedy the situation.

mmistroni; Hello,

No problem there, what is the return from terminal command ?:


cat /etc/apt/sources.list.d/*.list

As the directory "sources.list.d" is an alternate source containing additional files.



we still be looking

mmistroni; Hey,

Got it !

see:


#:description:This channel contains the partner software for karmic
deb http://archive.canonical.com/ubuntu precise partner
//
#:description:This channel contains the partner software for lucid
deb http://archive.canonical.com/ubuntu precise partner


Remove either one of those files, and all should be good.



seek and ye shall find
