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'.

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)?
