Is my /var directory OK, since /var/run isn't a symlink?

I am running Ubuntu 18.04. When I run:

ls -la /var

I get the following:

drwxr-xr-x 10 root root   4096 Jan  2 15:46 .

drwxr-xr-x 27 root root   4096 Jan 15 06:25 ..

drwxr-xr-x 10 root root   4096 Jan  6 06:15 cache

drwxrwxrwt  2 root root   4096 Jan 12 06:41 crash

drwxr-xr-x 25 root root   4096 Jan  4 11:06 Lib

lrwxrwxrwx  1 root root     11 Dec 27 07:22 lock -> ../run/lock

drwxrwxr-x  8 root syslog 4096 Jan 10 06:06 log

drwx------  6 root root   4096 Jan 15 06:03 run

drwxr-xr-x  4 root root   4096 Jan  3 14:54 snap

drwxr-xr-x  4 root root   4096 Dec 27 07:22 spool

drwxr-xr-x  6 root root   4096 Jan 15 06:03 tmp

AFAIK /var/run should be symlink to /run. I have some problems in my system as described in 'who' command has blank output when using SSH, so is it because /var/run is not a symlink?
Can I safely remove it and replace it with a symlink?

You're right that /var/run is normally a symlink.

However, if /var/run does not contain any files, it should be safe to replace with a symlink. If there are files, you should move them to /run first.

When the directory /var/run is empty, you can replace with a symlink like this:

$ rmdir /var/run

$ ln -s /run /var/run

Referring to your previous question, I guess this could be the cause of failure, since /run contains the socket /run/dbus/system_bus_socket.
