after some sleep I have a couple of additional comments: the /usr/share/application-registry/gdebi.applications file the mime list should be comma-delimited or at least that is what they did in the liboffice.application file (it is the only other file in the directory).
while the steps in my previous post got gdebi to work from Thunar & Opera it DID NOT fix Firefox. For firefox the only thing I have found to work was to set Terminal=true in the gdebi.desktop file. If you have multiple copies of this file make sure you change the one in: /usr/share/applications/gdebi.desktop: I have one at: /home/johndoe/.local/share/applications/gdebi.desktop it was created by trying to edit via the Whisker Menu I have another one at: /home/johndoe/.local/share/applications/gdebi.desktop it was created by trying to edit via MenuLibre <sigh> if anyone whishes to contact me they can do so @ whgi...@yahoo.com -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gdebi in Ubuntu. https://bugs.launchpad.net/bugs/1749728 Title: Installing packages fails when launched via Firefox ("open with") Status in gdebi package in Ubuntu: Confirmed Bug description: When launched from Firefox with the "open with" function, GDebi is unable to complete installing the package.
