Twas me, as that is a common problem for not having enough space. If you had found the rootfs thread then there are solutions to the problems.

Some of the threads can be found here and here

I must add - this was a guess on my behalf - as i'm not sure if it is full - if you have conky installed you can see how much space is left in your rootfs.

The device has a limited space available for applications, which is why people keep asking are they optified. If they are, they use up less space in the sacred rootfs area.
