I need to use an Epson utility to troubleshoot my Epson All-in-one L3110 printer. It will not run without qt4 libraries. I have found articles that say qt4 was removed from ubuntu 20.04. I found instructions on installing qt4, but they do not work (anymore). Here is my terminal session trying to install the libraries:
jim@Jims-Ryzen-Desktop:~$ sudo add-apt-repository ppa:rock-core/qt4
Cannot add PPA: 'ppa:~rock-core/ubuntu/qt4'.
The team named '~rock-core' has no PPA named 'ubuntu/qt4'
Please choose from the following available PPAs:
- 'qt4': Qt4 for Ubuntu 20.04
I am confused by the suggested remedy. All help welcome.
