I have tried to add a printer in CUPS, however, there were no Canon MP210 drivers. The manufacturer does not provide any LINUX drivers. Also, I tried this on bash:
(base)###:~$ sudo add-apt-repository -r ppa:thierry-f/fork-michael-gruz
(base)###:~$ sudo apt update
However, I've encountered errors like:
E: The repository 'http://ppa.launchpad.net/michael-gruz/canon/ubuntu focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
And then I could not install the driver:
(base)###:~$ sudo apt-get install cnijfilter-mp210series
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package cnijfilter-mp210series
Please give me any suggestions, I have lost hope... Do you think a virtual box (Windows install) would be the best thing to do?
P.S. However, when I had Linux Mint distro everything worked fine
