Hi
I need to install Magento 2.4.5 on my website.
I have access to terminal. and uploaded the installation pack to public html.
I am new to Magento.
I have 3 problems:
1- my composer version is 2.4.4 and when in try to update to 2.5.5 with this command "composer self-update", I got this Error![22.png 22.png](https://community.magento.com/t5/image/serverpage/image-id/27105i95673BAAC486CBC5/image-size/large?v=v2&px=999)
2- The Magento installer also can not install because of the old composer version

3- also the Magento on my Cpanel is an old version and I think I have to install through the Terminal
