Hello, newbie here,

I am unable to setup and use my HP Envy 5030 printer on my Lubuntu 20.04 system.

Steps to reproduce the problem:

I am trying to setup my printer via wifi.

1) I run hp-setup from the terminal.

2) I select the 'Wireless/802.11' option and click next.

3) I plug my printer in via usb cable and press next.

4) My printer is recognized and I press next.

5) An error dialog pops up saying "An I/O error occurred.
Please check the USB connection to your printer and try again.
(Device I/O error)". Moreover, the terminal displays a 'Channel write error'. (please see the attached screenshot).

Please find attached the results of the hp-check.log file; it is worth noting that a warning message is displayed in the file indicating that Ubuntu 20.04 is not supported.

Regarding the Missing Required Dependencies via the hp-check.log file:
libcups2 - is installed.
python3-pyqt4 - has been replaced with python3-pyqt5
gtk2-engines-pixbuf - is installed.

I am able to set up the printer with hp-setup when selecting the USB option. I am able to print but not scan.

I have previously installed the hplip package via the automatic installer on the HP website (https://developers.hp.com/hp-linux-imaging-and-printing), but this didn't work either. Important to note that the automatic installer does not support Ubuntu 20.04, so no surprise there.

Thank you in advance,

Owen
