As a workaround, apply the following steps:

  2. Recreate the missing /boot/grub/menu.lst file:

    # mv /boot/grub/menu.lst~ /boot/grub/menu.lst

  3. Reinstall the system packages:

    # DEBIAN_FRONTEND=noninteractive apt-get install -y -f

    Hello @Mohammad,

    The speed of Plesk installation depends on many factors like server hardware, internet connection quality, etc.

    15 minutes is ok and I am glad to hear that you have completed the process.

    How long is this process suppose to last?

    Based on reply for the customer support team, we ran the above commands via SSH and when navigated to Plesk. It looks like something is not going to end. Is it normal if it takes more than 15 mins on this screen?

    I was asked for server root access when tried to visit this page on new tab which I did.
