[Libguestfs] Re: libguestfs failure "mkdir: command not found ..."

Thank you for your help. I was able to find the problem with your help and fix it.  The problem was not in libguestfs or its Ubuntu package.  Something was messed up in my system. dpkg-query didn't return anything for a lot of packages.  I was able to fix this problem with apt install --reinstall for all these packages. Thanks again for your help. libguestfs is running now.
