The amd64 ISO of December 24th works great. I am currently typing from the
live system.
I put it a USB pendrive (the FSF member card actually) using Trisquel 7's
"USB Creator" (or whatever it is called). Although it looks stuck at some
point (at 42% and at 99%, when creating the permanent file), it all ended
well.
It was written here that the ath9k_htc firmware was missing from the older
ISOs. It was certainly true (I did not try these ISOs) but, with that latest
ISO, my Wifi works out of the box.
Some weird things in the ISO:
Why is the ugly "Galculator" present since the "Calculator" is present as
well?
What is "Icedove -> Thunderbird" in the "Other" category?
