Thanks a lot @Levone1 for the aarch64 rebuilds!
harbour-containers, qxcompositor and lxc-templates-desktop are now upgraded (with new features) and available in the Chum repository, so please make sure you used the new versions (which implies uninstalling the older versions because Chum cannot overwrite them). qxdisplay is not necessary anymore and is deprecated as of now.
literm will be in Chum repository too hopefully (but my latest build attempts failed, I am hesitating between trying to understand why or just simply fetching an older commit), so this should become the preferred source for installing the package.
