debain packege manager not installing packages

i'm trying to install an IRC client on my Debian Gnome Desktop.

Every IRC client comes up with a plethora of unresolved dependencies

i've tried apt-get and the GUI package manager when apt-get didn't want to auto resolve the dependencies.

the GUI package manager lists the app i want to install, then i click the check box to install it, click apply changes, and it looks like the progress bar goes from 0 to 100 real quick, and then it shows the package as installed...

but when i go to run the app, it is missing, and i go back into package manager and it shows not installed

i haven't had this problem before--both apt-get and package manager have been real good to me

thanks for suggestions

Check your /etc/apt/sources.list and confirm that it has sources for all packages, not just the Debian defaults.  It should look something like (not exactly like, unless you are running the "stable" distribution) the one below.

cat /etc/apt/sources.list
deb stable main contrib non-free
deb-src stable main contrib non-free

deb jessie-updates main contrib non-free
deb-src jessie-updates main contrib non-free

deb jessie/updates main contrib non-free
deb-src jessie/updates main contrib non-free

Open in new window

If your sources.list is correct (or correcting it doesn't solve the problem) then you may need to rebuild the installed packages database.

I tend to agree with Dr. Klahn - sounds like your /etc/apt/sources.list file has some how been munged.

Once fixed, do an apt-get update + then try your install again.

When you reinstall, paste your output into a comment in this question. Likely someone can help you debug problems which show up.

i wonder. is there an issue with having too many sources in your sources.list?  or can you just go nuts?   nuts within reason .. 10-12 additional source in addition to what comes preinstalled ...

i added a kali source for some ethical hacking projects i'm doing and a couple others ...  i wonder if i overdid it

Dr. KlahnPrincipal Software EngineerCommented:
I'd restrict the apt sources.list to only those supplied by the Debian project.
