Upgraded from Wheezy to Jessie, but aptitude still hits wheezy URLs

Question

I upgraded Wheezy to Jessie by following the release notes - chapter 4, but now when I do an aptitude update I get URLs containing wheezy in them:

deb-src http://ftp.ro.debian.org/debian/ jessie-updates main contrib non-free

#backports
deb http://ftp.ro.debian.org/debian/ jessie-backports main contrib non-free

Is this OK? How can I remove the Wheezy URLs?

PS: apt-get update has the same output. The upgrade process went fine.

Answer 1

For others reading this:

Hit https://deb.nodesource.com wheezy is not a distribution managed repository. You have to maintain/update foreign repositories yourself. As you already mentioned, you fixed it already.

Answer 2

In /etc/apt/sources.list.d/ I had another repo that pointed to wheezy. I changed that to jessie and the problem is solved!
