The Hub is now installed on supported platforms via the corresponding package manager. Please see the documentation at https://docs.unity3d.com/hub/manual/InstallHub.html#install-hub-linux to install the Hub. You may want to clean up the files and edits from these steps prior to moving over to the package. There is currently a bug in the Linux Hub where Hub links do not open the Hub. Additionally, searching for and launching the Hub in GNOME doesn't work. Until the issue is fixed in the official build, here is a completely unofficial workaround that should get you going. Note that this is only tested on GNOME with no path configuration changes. You can tell if you affected by this bug by checking for the existence of ~/.local/share/applications/appimagekit-unityhub.desktop. If this file does exist, you should be OK. Otherwise, you can work around the issue by applying the following steps: 1) Create the file ~/.local/share/applications/appimagekit-unityhub.desktop with the following contents, substituting your correct home path and path of the UnityHub.AppImage file: [Desktop Entry] Name=Unity Hub Comment=The Official Unity Hub Exec="/home/SubstituteMe/.local/bin/UnityHub.AppImage" %U Terminal=false Type=Application Icon=appimagekit-unityhub MimeType=x-scheme-handler/unityhub; Categories=Development; X-Desktop-File-Install-Version=0.24 TryExec=/home/SubstituteMe/.local/bin/UnityHub.AppImage2) (Updated, see old step below if you have issues.) Run the following command to register the URL scheme with XDG: xdg-mime default appimagekit-unityhub.desktop x-scheme-handler/unityhub 2) Create or open the file ~/.local/share/applications/mimeinfo.cache. Add the following content. If the file already exists, leave out the first line: [MIME Cache] x-scheme-handler/unityhub=appimagekit-unityhub.desktop;You should now be able to open Hub links and search for it in GNOME.
