I re-created the same issue on another install, this time Ubuntu-Budgie 19.04. Same issue happened, same solution fixed it.
Detailed steps I followed to fix the issue: 1. Go to https://developers.hp.com/hp-linux-imaging-and-printing/gethplip . 2. Download latest version for Ubuntu . At the time of writing latest version is 3.19.3 . 3. Download hplip-3.19.3.run file, remember to change permissions to make it executable. 4. Remove hplip installed by your distribution repositories. 5. Download hplip-3.19.3-plugin.run and hplip-3.19.3-plugin.run.asc from https://developers.hp.com/hp-linux-imaging-and-printing/plugins . 6. run hplip-3.19.3.run in a terminal, follow instructions on screen. 7. During printer setup process, when asked, always use interactive mode instead of gui. When asked for plugin, select path instead of download from server, provide path including full name of hplip-3.19.3-plugin.run . -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to hplip in Ubuntu. https://bugs.launchpad.net/bugs/1825717 Title: hplip issue during hp-setup - stuck at plugin install Status in hplip package in Ubuntu: New Bug description: Fresh install of Kubuntu 19.04 Installed hplip from repositories, available version is 3.19.1+dfsg0-1 When I start setup with hp-setup, this happens: 1. I am asked connection type. I select network ethernet 2. My printer is detected. I select it and hit next 3. I am told about the proprietary plugin to download. I confirm, accept download. I enter my user's password. I get a confirmation that the plugin is correctly Installed. 4. On next screen, I get a warning and cannot continue installation. I am told this printer needs a proprietary plugin to work correctly. After this I am stuck in a loop between points 3 and 4. I also tried to start hp-setup from super user on command line. but no way around this issue. What I did next, I manually downloaded hplip-3.19.3.run from HP website. Removed version of hplip installed from repositories. Installed from manually downloaded package, followed the very same steps. Everything worked fine and printer is installed successfully. I hope this information is useful.
