I am trying to install Gitkraken on my Jetson nano and came across the same error, as you say it seems snap is fetching the wrong binaries. I got past this one with: “sudo apt install binfmt-support qemu qemu-user-static” - but it still wont launch as it says it is unable to find the library: lib64/ld-linux-x86-64.so.2 - tried various things but still not able to get past it (strace below). Looked to see if I could download arm64 compiled binaries from the Gitkraken website but couldnt find anything matching. Qemu doesn’t seem the way to go either as I know it will be incredibly slow as Gitkraken can be quite intensive, really want to get it to work for Nano as I now have a development machine 90% there!
