I don't have a Linux arm64 machine, what's the output of lux -v?

What's your OS (name and version)? I tested it on a Ubuntu 20.04.6 LTS (GNU/Linux 5.4.0-99-generic aarch64) machine, and it works fine:

root@master:~# ./lux -v

Note the high amount of rt_sigreturn

Others strace logs also pointing to a lot of SIGURG. But I can't point where is it coming from. v0.23.0...v0.24.0

Please try with v0.24.1, I have bumped the go version to 1.22, hope this is a cross-compile issue

I updated the v0.24.1 version, and it still takes 2-3 minutes to start for the first time, and the version number is still incorrect, it shows v0.0.0.

Which binary did you download? From https://github.com/iawia002/lux/releases/tag/v0.24.1 here?

NOTE: The version number will only be displayed in the binary file from the release page

Through the following operations, lux can start quickly, but the version number is still incorrect.

升级0.24.1以后，还是同样的问题😂

Regarding the version display, I installed older versions one by one until v0.20.0 would print the correct version number.
