When trying to enable role::visualeditor:
==> default: Error: /Stage[main]/Zotero/Package[xulrunner-dev]/ensure: change from purged to present failed: Execution of '/usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install xulrunner-dev' returned 100: Reading package lists... ==> default: Building dependency tree... ==> default: Reading state information... ==> default: Package xulrunner-dev is not available, but is referred to by another package. ==> default: This may mean that the package is missing, has been obsoleted, or ==> default: is only available from another source ==> default: ==> default: E: Package 'xulrunner-dev' has no installation candidate
In T107302: Package and test Zotero for Jessie it was decided not to try and backport packages to make Zotero run on Jessie. This means that we won't be able to provision and test Zotero on a Jessie-based MediaWiki-Vagrant deploy.
