For Linux, there are three options available on Download - Legend page.
For me, both Appimage and .deb install resulted in the following line in my syslog:
May 19 22:45:08 pop-os kernel: [...] traps: legend trap int3 ip:[...] sp:[...] error:0 in legend[...]
I would love to give you more detail, but this is literally the only line that gets put into syslog.
Snap doesn’t work right away either - but that’s only because it can’t verify certs while installing so one has to put
--dangerous with snap install command, like so:
sudo snap install Legend-2.0.8-linux-amd64.snap --dangerous
After which it starts up fine. I feel this should be indicated somewhere, ideally on the download page itself.
