Installing Trisquel 11

Following these steps always worked for me:

EDIT: I assumed you had already verified the iso file after downloading it. If not, you can follow the instructions there: https://trisquel.info/en/wiki/verify-trisquel-download (using the name of the iso you downloaded where expected, so the .iso and .iso.asc file names match).

I tried Trisquel 11.0 too, and it is good. I plan to use it for my learning and teaching, Thanks. This community seems not active, and let's work hard to make it better. :)
