VSM: Could not get hold of varnishd, is it running?

[Meken]

I am running Ubuntu 20.04.

Recently upgrade of bash (apt update && apt upgrade) causes
varnishlog/varnishtop/varnishtop not working:
 <http://us.archive.ubuntu.com/ubuntu> http://us.archive.ubuntu.com/ubuntu
focal-updates/main amd64 bash amd64 5.0-6ubuntu1.1

varnishstat
.....
VSM: Could not get hold of varnishd, is it running?

Change to" sudo varnishstat" no use

(but varnish is running)

Tested on Varnish 6.2.1 also 6.4 master.

So it is a bug of Ubuntu or Varnish?

The only fix is to roll back to cancel the upgrade.

ps aux | grep varnish

Any idea? Thanks!
