I fixed the OpenJDK issue by creating a separate ubuntu.list file in my
/etc/apt/sources.list.d/ directory with my local Ubuntu mirror for 12.04 to
nab the main and universe repos. I had to manually import the Ubuntu Archives
key (since Trisquel does not have it), install OpenJDK u25, disable the
Ubuntu repos, and re-run apt-get update.
Want to know another issue? There were at least 30+ updates for software like
apt that were available in Ubuntu 12.04 that were not yet available for
Trisquel 6.
PLEASE PLEASE PLEASE SYNC THE TRISQUEL REPOS!!!
