Before installing YugabyteDB, ensure that you have the following available:

1. One of the supported operating systems.

2. Python 3.11. To check the version, execute the following command:

   python --version
   

   Starting from Ubuntu 20.04, python is no longer available. To fix this, run sudo apt install python-is-python3.

3. wget or curl.

   The instructions use the wget command to download files. If you prefer to use curl, you can replace wget with curl -O.

   To install wget:

   • On CentOS, run yum install wget
   • On Ubuntu, run apt install wget

   To install curl:

   • On CentOS, run yum install curl
   • On Ubuntu, run apt install curl
