Hi,

When I run aptitude update, I keep getting this error message:

W: Duplicate sources.list entry http://ftp.nl.debian.org etch/main Packages
(/var/lib/apt/lists/ftp.nl.debian.org_debian_dists_etch_main_binary-i386_Packages)

W: You may want to run apt-get update to correct these problems

When I run aptitude update a second time, it doesn't complain no more.
But the next time I run aptitude update, the warning appears again.


Should I remove the following line from my /etc/apt/sources.list:

deb http://ftp.nl.debian.org/debian/ etch main

or should I remove the following file from /var/lib/apt/lists:

ftp.nl.debian.org_debian_dists_etch_main_binary-i386_Packages

or should I do nothing at all and just run aptitude update twice?


Thanks, Manon.



Here's my etc/apt/sources.list:
