Hi Dan,

You are right. The owner of my / directory was not root but my regular
user. I set it back as root and now the problem is solved. I don't know how
it was changed, because I manually never changed the owner of my /
directory.

Anyway, thank you very much for providing support, solution and bug fix.
I wish you a great time and health ahead.

Yours sincerely,
Vivek Shukla
