The following page on the Atera website claims, "You can use AnyDesk on your Windows, Mac OS, or Linux device to connect to all your customer devices."

However, the only available client for Linux is AnyDesk and it doesn't work. I contacted Atera Tech Support about this and was told:

"We would like to bring to your attention that for the time being, our official support for AnyDesk is primarily focused on Windows and MacOS operating systems.", and, "Indeed, the documentation will be also reviewed and updated."
