Can you retry running it as: ./passt -f -d so we can see if something strange is going on (-f stands for --foreground, -d for --debug)?

It's probing /tmp/passt_1.socket and failing to get an answer. This just happened to another user, in that case seccomp was terminating passt because on his system daemon() called a different set of syscalls compared to my system: https://passt.top/passt/commit/?id=1fc6416cf9446cbf75818fd61772610e74709065 and I expect some more issues like these at the beginning, I didn't test it on different distributions yet. By the way, I'm working on adding tests for a few distributions right now, so that we can catch those early. -- Stefano
