Even if Ubuntu is the only officially supported distro for Remote Desktop Manager, we know Linux is all about choices and we would not want to change that.
In that optic, here is a little guide to help you install Remote Desktop Manager Linux on your preferred, unsupported distro.
First of all, dependencies:
glibc 2.29
libwebkit2gtk-4.0
ca-certificates
libsecret-1-0
gnome-keyring
libvte-2.91
If you are installing Remote Desktop Manager Linux on a distro supporting deb files, you are done. Simply install the deb package and everything should be good to go. You can start Remote Desktop Manager using the menu icon or the remotedesktopmanager terminal command.
You can also opt to install the net.devolutions.RDM flatpak package from flathub.
Otherwise, you can manually install Remote Desktop Manager Linux using the following steps:
Extract deb file content. (ar x RemoteDesktopManager_x.x.x.x_amd64.deb)
Extract data.tar.xz content. (tar -xf data.tar.xz)
Copy bin/remotedesktopmananger to /bin
Copy usr/lib/devolutions/RemoteDesktopManager to /usr/lib/devolutions/RemoteDesktopManager
You can now start Remote Desktop Manager using the remotedesktopmanager terminal command.
