How to install Bitcoin-Core package on Ubuntu/Debian based system?
Excuse me, could you please explain in detail the steps required to successfully install the Bitcoin-Core package on a system that's running Ubuntu or Debian? I'm not very familiar with the process and would appreciate a step-by-step guide, including any pre-requisites or additional software that might be needed. Additionally, could you also clarify if there are any security considerations that I should be aware of during the installation process? Thank you in advance for your assistance.
