How do I install the following ?

I can install these packages directly via apt-get:

• libcorelinuxc2a
• libedbus1
• libedje1
• libefreet1

Maybe the others have synonyms? I don't know them. Are you already running Trisquel?

OK , yes running Trisquel - just tried this :-

apt-get install libedbus1
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies.
libedbus1 : Depends: libecore1 (>= 201209151019) but it is not going to be installed
E: Unable to correct problems, you have held broken packages

So , tried this

apt-get install libcore1
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libcore1

Any ideas ?
