APTonCD

[onebir]

This is in the repositories & I'd like to use it, but when I tried to install it this was the result:

onebir@onebir-laptop:~$ sudo apt-get install aptoncd
[sudo] password for onebir:

After this operation, 2,007kB of additional disk space will be used.
WARNING: The following packages cannot be authenticated!
  aptoncd

I guess this shouldn't happen with packages available via the software center... perhaps this should be a bug report?

But more generally, how can someone decided if a package is "safe" to install in this?

Edit: just ran into the same warning trying to install wicd.

Post the contents of /etc/apt/sources.list here.

Sorry for the delay. Everything looks normal. aptoncd and wicd are from the "Universe" repository, which is not "officially" supported (hence the warning) but are safe to use...
https://help.ubuntu.com/community/Repositories/Ubuntu

I assume you're seeing the warning because you are using apt-get to install and you wouldn't see that warning if you used the Software Center (I can't test that as I'm not currently on Ubuntu).
