I don't know, this was made by Synaptic. I have been receiving regular
updates, only thing I did was adding the Tor part.
I run those commands, and got this:
$ sudo apt-get clean
$ sudo apt-get update
Get:1 tor+http://ppa.launchpad.net/i2p-maintainers/i2p/ubuntu xenial
InRelease

I don't know why only i2p PPA was used here, I was expecting onionshare PPA
and regular trisquel updates as well.
