The error causes when using the command `./install_mkl.sh` to install mkl tools

[jacksonchen1998]

Actually, when I use apt-get update in my PC.
I also get this bug.

My OS

Distributor ID:	Ubuntu
Description:	Ubuntu 22.04.3 LTS
Release:	22.04
Codename:	jammy

./install_mkl.sh: Your system is using debian-style package management.
./install_mkl.sh: You must be root to install MKL.

Restart this script using the 'sudo' command, as:

  sudo ./install_mkl.sh -sp debian intel-mkl-64bit-2020.0-088

We recommend adding the '-sp debian' options to skip the MKL and distro
detection, since this has already been done. This minimizes the number of
programs invoked with the root privileges to keep your system safe from
unexpected or erroneous changes. Also, if you are setting the CC environment
variable, sudo might not allow it to propagate to the command that it invokes.

Run the above sudo command now? [Y/n]:y
+ exec sudo ./install_mkl.sh -sp debian intel-mkl-64bit-2020.0-088
+ apt-get update

1. cd /etc/apt/sources.list.d
2. open the file with the keyword webupd8
3. comment the first line

And it works. When I use apt-get update, it won't raise the error.
