Untrusted packages

[Dotan Cohen]

While installing cw I got this rather stern warning:

saturn:~$ sudo aptitude install cw
[sudo] password for dotancohen:
The following NEW packages will be installed:
  cw unixcw{a}
0 packages upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
Need to get 64.0 kB of archives. After unpacking 262 kB will be used.
Do you want to continue? [Y/n/?]
WARNING: untrusted versions of the following packages will be installed!

Untrusted packages could compromise your system's security.
You should only proceed with the installation if you are certain that
this is what you want to do.

  unixcw cw

Do you want to ignore this warning and proceed anyway?


I do have some non-default repos installed, but I have never seen this
warning. Also, though Aptitude isn't telling me, I would assume that
cw is being installed from canonical repos, it is a common enough
package. Why does this particular package elicit the warning, while
others do not?

This is on Kubuntu 11.10. Thanks.
