I’ve noticed this several times now. Trying to manually install a deb with Gdebi has an extended delay without actually bringing up the authorization dialog. It can take multiple times before the deb will actually get authorized.
Recently while attempting to install discord, there was an error:
dpkg: error: unable to read filedescriptor flags for <package status and progress file descriptor>: Bad file descriptor
I redownloaded the file with a different browser (I use Pale Moon but I switched to Firefox to ensure this wasn’t simply a bad download.) Same result. Any ideas?
EDIT:
Tossing the error into a search engine shows this is something which seems to happen off and on again. Reading the comments in a Launchpad bug report I saw mention that manually installing from the terminal seemed to still work, the issue seemed to be only inthe Gdebi-gtk installer. I can confirm that, I was successful installing my debs manually from the terminal with this command:
sudo dpkg -i my-file.deb
