It seems like you are experiencing issues with HPLIP on Ubuntu 20.04 LTS. Here are some steps you can take to address the problems:
libcups2 and cups Service: Ensure that the libcups2 package is installed. You've already checked this, but you can run the command again to be sure: sudo apt-get install libcups2 libcups2-dev Check if the CUPS service is running: sudo service cups status If it's not running, start it: sudo service cups start python3-pyqt4 Package: The python3-pyqt4 package is not available in the default repositories for Ubuntu 20.04. You might need to find an alternative solution or use a compatible version. As of Ubuntu 20.04, Python 3 and Qt 5 are the default. gtk2-engines-pixbuf Package: Ensure that the gtk2-engines-pixbuf package is installed: sudo apt-get install gtk2-engines-pixbuf python3-dbus.mainloop.qt Package: Similar to python3-pyqt4, the python3-dbus.mainloop.qt package may not be available. You can try installing python3-pyqt5 instead: sudo apt-get install python3-pyqt5 After making these changes, run hp-doctor and hp-check again to see if the issues are resolved i resolved it for https://compassionify.com/somatic-therapy-nyc/ blog.
