Re: [Trisquel-users] No Software Updates Are Available

You have this ppa installed ppa:langdalepl/gvfs-mtp.
It is used for mtp, but you should already have support in package  
gvfs-backends. There is no trusty support on the ppa, so you probably  
shouldn't be using it anyway. It might have been useful for Trisquel 6.  
Removing the ppa might fix your problem.
