muon software center refuses to cooperate [SOLVED]

[dex]

Dear friends,
I have a problem that was bugging me for a few days now. Whenever I want to download and install a software through muon software center or even update my system I get the following error:

<"Another application seems to be using the package system at this time. You must close all other package managers before you will be able to install or remove any packages"l>

The thing is, there is no other software that I can see using the package system. I opened up system monitor and didn't find anything telling me that there is a process coming from muon software center. Any ideas?

Re: muon software center refuses to cooperate

You may have Muon package manager open.
There are 2 Muon thingies.
The Muon Software center, and the Muon package manager.
If you installed Synaptic, check to make sure that is closed as well.

Re: muon software center refuses to cooperate

No synaptic manager installed. Both of the muon managers are closed...
I have a feeling, that removing muon managers and installing them again would be a good idea. But considering the restricting circumstances, can anyone provide a step-by-step description on conducting such a procedure, if it is a good idea?

Not a good idea. Instead, look for an existing lock file that didn't get removed properly.

Open a console and type:

sudo rm /var/cache/apt/archives/lock

Then launch either (but not both) Muon Software Center or Muon Package Manager and see how it fares now.

I also experienced problems with Muon installer, so I installed Synaptic and the day was saved.

I often experienced this problem in Ubuntu even though i shut every application down. A reboot used to remedy this bug

Okay, I did just what you suggested, the lock is gone. However that didn't fix it. I opened up Muon software center and tried to install an app to test out if it would let me. Same error.

Re: muon software center refuses to cooperate

Try it from the command line, it will give you a better error code.

So you open Konsole and typ:

sudo apt-get install thisprogram

Obviously you need to replace thisprogram with the name of the application you want.
Now look for the feedback you get and follow up.

You are a day saver! Thanks, it worked. When I entered the apt-get install command, he told me there was a problem: "dpkg was interrupted" and told me what to do about it "you must manually run 'sudo dpkg --configure -a' to correct the problem." Which is exactly what I did. I ran the update, and everything installed, my muon is back on track.

I am having the same exact problem with Muon and have tried all the advice listed here but still cannot get muon to cooperate and install wine. Any other suggestions?

This did the trick for me:

First I ran:
sudo rm /var/cache/apt/archives/lock

Then I rebooted and then:
sudo dpkg --configure -a

Which tidied up an update that had failed to complete, after that I started Muon and it was ok again.

sudo rm /var/lib/dpkg/lock

also can become necessary after Muon hangs.
