My problem is as follows. I am running 3 different laptops. Mint 13, Mint 16 and Ubuntu 14.04. All three is running latest steam deb. Ubuntu is ok, no problem.
But...On both of my Mint boxes I get this: "E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable) E: Unable to lock directory /var/lib/apt/lists/"
It doesn't in any way break my system but it's annoying :/ Using --> "sudo rm -fv /var/lib/apt/lists/* sudo apt-get update" takes care of the problem until next reboot.
In other words, when Mint is running the Update Manager, the output is that the apt-get process is busy. It takes for ever to finish and/or it hangs... This happened after the latest steam client upgrade. I have trialed this on one of my laptops, re-installing Mint 16 from scratch and then adding the steam client. Without steam = no problem, with steam = problem. I have also run trials in both Virtualbox and vmware. Same result.
When I use synaptic to remove steam all is good. So I am wondering if steam is hogging the apt-get process, taking a higher priority? A steam client bug maybe?
