Oh, i think that masive traceback is trying to say

85    futex(0xc000180848, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...>
80    <... newfstatat resumed>0xc00111b898, 0) = -1 ENOENT (No such file or directory)
80    newfstatat(AT_FDCWD, "/sbin/blkid", 0xc00111b968, 0) = -1 ENOENT (No such file or directory)
80    newfstatat(AT_FDCWD, "/bin/blkid",  <unfinished ...>
79    <... tgkill resumed>)             = 0
80    <... newfstatat resumed>0xc00111ba38, 0) = -1 ENOENT (No such file or directory)
79    nanosleep({tv_sec=0, tv_nsec=20000},  <unfinished ...>

that blkid is not available. A better captured error message would be nice here.

Hi @xnox,
It's hard to tell from the attached log as to the root issue but it definitely seems (as you found) it's somewhere in Python checks executions. Due to the fact that Python is loaded through C APIs by Go, the error messages can get lost between the two runtimes without the right flags and tooling.

If your strace output is accurate, you have already found the problem with your build and you can find the relevant code here. If you're interested in deeper C-level debugging, I'd recommend using the gdb troubleshooting steps. It is a bit unexpected that you're not getting the Python error output from the try/catch though but there's not enough info in the bug report to indicate why and/or if this is connected somehow to how you're building the Agent.
