I installed Trusty Tahr on my old Dell Studio 1537 a few hours ago. Since then I've been trying to install pipelight and failed miserably. I get the unmet dependencies problem as many people have before me. I've tried several suggestions that I've found both here and in other forums.
# Clean + -f install #
sudo apt-get clean
sudo apt-get -f install
sudo dpkg --configure -a
sudo apt-get -f install
# Output: 0 upgraded, 0 newly installed, 0 to remove, and 0 not upgraded.
I've also tried removing the repository and adding it again with no luck. I tried purging the repository then adding it again as suggested by this post and now terminal won't even find the package, much less try to install. I also tried installing aptitude as I've read that it may be able to install packages somewhat forcibly (also failed, because I also get unmet dependencies when trying to install aptitude). Lastly I also get unmet dependencies when trying to install gimp, which leads me to believe it might be a system problem instead of a package/dependency problem, so I went so far as to re-install the system from scratch with no luck. So far the only things I managed to install in the system are the firmware-b43-installer for the wireless (Broadcom BCM4312) card and ubuntu-restricted-extras.
So now, I'm looking for solutions that I haven't tried yet or something I might have missed. Any suggestions?
