Installing trisquel 5.5 using a USB drive the installation seemed to freeze
similar to what you describe. In the gui there was the "Please wait" with the
cursor spinning. It appears to have stopped at the same spot as your
screenshot.
In my case it appears there is a malformed command somewhere in the
installation script. Using "top" I noticed a line similar to the following:
"sudo wget -o /dev/null -O /dev/null
ftp://in.archive.trisquel.info/trisquel//speedtest";
I believe the line is incorrectly formed as a server at
in.archive.trisquel.info does not exist but archive.trisquel.info does. In
addition I'm not sure the double "//" is correct. Using "sudo top" to
identify and kill this offending command, the installation seemed to move
ahead and complete.
Hope this helps work around and perhaps fix the bug.
