Error: /proc must be mounted when executing vmstat

[Mirr0ch1]

Please fill out the below information:

• Your Windows build number:
  17134

• What you're doing and what's happening:

  • trying to run vmstat, results are like:

mirro@LAPTOP-MiP:/$ vmstat
procs -----------memory---------- ---swap-- -----io---- -system-- ------cpu-----
r  b   swpd   free   buff  cache   si   so    bi    bo   in   cs us sy id wa st
Error: /proc must be mounted
 To mount /proc at boot you need an /etc/fstab line like:
     proc   /proc   proc    defaults
 In the meantime, run "mount proc /proc -t proc"

• yet /proc has already listed as mounted

mirro@LAPTOP-MiP:/$ mount

binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noatime)
C: on /mnt/c type drvfs (rw,noatime,uid=1000,gid=1000)

I'm aware of this issue has been marked as solved under #105. Apparently there's still some bug need to be fixed. Please look into this problem, huge thanks.

The error spewed by vmstat(1) is misleading; it is just confused by the lack of /proc/vmstat and assumes /proc must not be mounted at all. Dupe #1071. Russel's request for a blocking scenario posted over there (sic) always helps.

So I"m on the very latest versions and I still see the problem with vmstat -SM 1

We are seeing the same problem.
