On Ubuntu 22.04 arm64 server (ubuntu-desktop package installed), I downloaded the SmartGit Linux x64 bundle, I removed the included jre and git directories, I then installed openjdk-11-jre and git with apt and now I can now run SmartGit.
It would still be nice to have directly a downloadable Linux aarch64 bundle, but at least it works now :-)
Thank you.
