trisquel_10.0_amd64.iso, dated 29-Sep, and downloaded from cdbuilds.trisquel.org
The live session looks great, and has a fully functional screen reader. When I installed it to a test machine, there was an error, "temporary failure resolving archive.trisquel.org". I let the install finish, anyway. When I booted the new system, I had a screen reader on the login session, but no screen reader on the user session. Could it be that the installer crashed and failed to set up the user correctly?
Thanks,
Dave H.
Maybe what I have just written in https://trisquel.info/forum/ca-certificate-issue-while-installing-any-package#comment-161059 may help you (minus the second paragraph about UEFI support).
