How do you fix unmet dependency when installing Cinnamon on Ubuntu 14.04?
I attached a bunch of info on what I've tried so far.
Attempt 1:
So I found this question on how-to install cinnamon on ubuntu 14.04. I tried the first ppa repository and it failed with "unmet dependency... cinnamon-screensaver".
Attempt 2:
I then used ppa-purge to get rid of that repository. Then did apt-get clean. Then I tried the second ppa repository in the how-to guide. I tried to install cinnamon again... and it failed the same way:
root@wheaton-ubuntu14:~# apt-get install cinnamon

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:
cinnamon : Depends: cinnamon-screensaver (>= 2.6.0) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Attempt 3:
I then looked up how to fix unmet dependencies and found this guide with 300+ upvotes so I thought I was all set!
Attempt 4:
I then saw someone was successful with aptitude install cinnamon
. But every time aptitude said "is this solution acceptable" cinnamon was still marked as "not installed". So I interrupted the interactive process.
Attempt 5:
I google'd the error and saw a debian thread somewhere with "oh there's a bug fix in git." but then the thread ends with "oh thanks" but no instructions on how to fix the issue.
Not sure where to go from here.
update - as per a request in the comments here is the requested info:
root@wheaton-ubuntu14:~# lsb_release -a; uname -a; apt-cache policy cinnamon cinnamon-screensaver; apt-get install cinnamon-screensaver
