I have installed these printers on several Ubuntu 24.04 systems without any issues. However, the same setup no longer works on Ubuntu 26.04. I am trying to install two shared network printers: smb://server-name/printer-name https://server-name:port/printer-name I installed system-config-printer (and smbclient) to configure the printers. The printer installation appears to be successful, and printing a test page always works. However, when printing actual documents (PDFs from Okular, files from GNOME Text Editor, web pages from Firefox, etc.), only the first one or two print jobs are processed successfully. After that, printing stops working entirely. Another thing I noticed is that I am never prompted for authentication credentials. On Ubuntu 24.04, a credentials dialog would always appear when needed. I also receive a problem notification mentioning the xdg-desktop-portal- gnome module. Do you have any idea what might be causing this issue? I have reproduced the problem on two different laptops with fresh Ubuntu 26.04 installations fully updated to the latest packages. I have attached the /var/crash file for reference. If you need any additional information or would like me to perform further tests, I would be happy to help.
