I'm installing Islandora and am up to
https://wiki.duraspace.org/display/ISLANDORA/milestone+5+-++Installing+the+Islandora+Essential+Modules => "Install dependencies"
When I run apt-get install pdftotext poppler-utils I get
"E: Unable to locate package pdftotext"
and when I run apt-get install gs I get
"Package gs is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'gs' has no installation candidate"
I'm running Ubuntu 16.04
TIA,
Ilana
