Recently, when VPS uses the "free" command to view RAM usage or other commands, it displays

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"

I have reinstalled the system multiple times, but it still hasn't solved the problem.
May I ask how to solve this malfunction?

Which os do you use? Did you create faulty entries in the fstab(in my case fstab is empty)?

Hi, My problem still exists. In order to try to solve the problem, I have reinstalled different systems, including debian 10, debian 11, Ubuntu 20.04, etc., Currently, I am using Ubuntu 20.04, but the problem has not been resolved. My fstab file is also empty, I haven't created any entries in the fstab.

And /proc appears to be mounted normally, but when I tried the command 'cat /proc/cpuinfo' or 'cat /proc/meminfo', it displayed 'Permission denied'.
