Unable to install packages (Umet dependencies)

[Mister08]

Hey Guys, I couldn't find a solution after searching for about a half an hour on the forums so I made a new thread

I'm relatively new to KDE and to Linux in general. I recently migrated my laptop to Kubuntu 12.04_x64 after my Windowsbox was corrupted.

I *really* doubt any of this is relevant or will help but here is my Laptop's specs

CPU - AMD Phenom II quad-core mobile processor N950 P940 (2 MB L2 cache, 1.60/1.70 GHz, DDR3 1066 MHz, 25 W
GPU - ATI Radeon HD 4250
RAM - 8GB
HDs - One 320 GB SATA
Optical Drives - One 8X DVD-Super Multi double-layer drive

Anyway, I've been running Kubuntu for about a week now, and am now unable to install any packages. I've experienced this problem before, and naturally tried
$ sudo apt-get clean and $ sudo apt-get autoclean
$ sudo apt-get -f install

This did not work in the slightest. I am unable to install from Muon Software Center, Ubuntu Software Center, or using apt-get

This is the error I'm recieving

andrew@Andrew-Laptop:~$ sudo apt-get clean
andrew@Andrew-Laptop:~$ sudo apt-get -f install

When attempting to install anything afterword I am greeted by the now familiar
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
openshot : Depends: python-mlt2 but it is not installable or
python-mlt but it is not installable or
openshot-mlt but it is not installable
Recommends: openshot-doc but it is not installed
E: Unmet dependencies. Try using -f.

How can I fix this?

What does "sudo dpkg --configure -a" tell you? Also, do you have any extra repositories, over and above the default repos?

The only thing that may? count is I have the Ubuntu Software Center in addition to the default Muon.

Just to be sure, have you run sudo apt-get update at all? If not, run that to refresh your package info, then try sudo apt-get -f install and sudo apt-get -f install

[vinnywright]

how did you add openshot?

and why ppa-purge?

I have, yes. Unfortunately it gives me a very similar error regarding the same 3 packages that are causing all the mayhem

Openshot was installed from .Deb off their website. Reading throught it again I see that it needed to be installed through PPA. ---feeling stupid for not reading more carefully, tired or not.

ppa-purge was something suggested by this thread askubuntu.com/questions/140246/how-do-i-resolve-unmet-dependencies--- I havent used it yet but was basically going down the list trying fixes. I installed it half-expecting to need it but decided to come here asking for help before I accidently rendered my system unusable.

[Mister08]

I uninstalled openshot
$ sudo apt-get remove openshot
updated and then ran $sudo apt-get -f install

... and it all seems to be working again.

Thanks for the help guys!!! I'm glad it was a simple (however idiotic) user error

[vinnywright]

thare is a ver. of openshot you can get with your package manager ,,,ver. 1.4.0-1ubuntu1
