I searched but found no one mentioning this before...

In APPLICATION MANAGER -> TOOLS -> LOG I found the following error:

hildon-application-manager 2.0.2
W: Couldn't stat source package list http://download.talinux.tal.org chink/free Packages (/var/lib/apt/lists/download.talinux.tal.org_pub_maemo_dists_chinook_f ree_binary-armel_Packages) -stat (2 No such file or directory)
W: You may ant to run apt-get update to correct these problems

Being new to Linux, how do I go about fixing this -or- does it need to be fixed?

The only Catalog that I have that points to that site is "Mapper".

http://download.talinux.tal.org chink/free

should be

http://download.talinux.tal.org chinook/free

I looked for obvious errors like this in each catalog but didn't find any.

I ended up deleting all catalogs and re-adding from www.gronmayer.com but now I get other errors showing up....malformed lines in the catalog list and missing public keys for a number of repositories.
