Whenever I run a yaourt command that requires sudo (eg., yaourt -Syu), yaourt will hang for 8 - 15 (sometimes up to 30) seconds before prompting for a password. This 'hang' only happens the first time yaourt is called after startup, and subsequent runs are normal. I can't tell if this is something wrong with my groups, wifi, or anything else.
I've attached an strace file of the command being run. Something interesting to note is that about 97% of the processing time is spent on a wait4() system call. It's waiting on a [{WIFEXITED(s) && WEXITSTATUS(s) == 0}] call, but I can't find out why that's hanging.
Here's the full strace, generated with
strace -i -k -C -y -w -r -T -o strace_yaourt.txt yaourt -Syustrace_yaourt.txt
And here's only the wait4() calls: strace_yaourt_wait4.txt
The number at the end of the line is the amount of time spent running the command
Is this a bug or is it something wrong with my machine?
Here's the output of uname -a:
Linux arch 4.13.8-1-ARCH #1 SMP PREEMPT Wed Oct 18 11:49:44 CEST 2017 x86_64 GNU/Linux
I'm having a problem I don't see any issues for.
