Magento Upgrade from 2.2 to 2.4.5 - Big trouble with PHP version

I spent 1 week trying to upgrade Magento from version 2.2 to 2.4.
In order to proceed I have downloaded and I am using composer 1.
My PHP version is 7.1 - Perfectly compatible with Magento 2.2.
With composer 1 I was able to get a "composer require" without errors.
I then launched the "composer update" command but it goes into error due to the lack of php 7.4 or higher.
Now: I could also update the php and finish the "composer update" but then the "magento/upgrade" will not work because it is the one of Magento 2.2 which only works with php 7.1
Do you have solutions?
I am aspects to upgrade Magento
You have 2 solution:
1, If you dont want to upgrade magento 2.2 to magento 2.4, you can remove php7.4 and use php7.1 again.
2, Upgrade magento version to 2.4.x:
With magento <=2.4.3, you can use php7.4
With magetno >=2.4.4, you can use php8.1
Step by step to upgrade magento version you can read it here Upgrade magento version
For Magento 2.4.4, the minimum requirement of PHP version is 8.1 so you need to make sure to change the PHP version then run the composer require to upgrade.
Check the official documentation: https://devdocs.magento.com/guides/v2.4/release-notes/release-notes-2-4-0-open-source.html

Magento Enterprise Edition Upgrade from 2.3.5-p2 to 2.4.0 getting error

I am a newbie for the Magento enterprise edition. I am upgrading Magento 2.3.5-p2 to Magento 2.4.0 in Enterprise Edition.
Following commands used with MySQL 5.7 and php7.3:
composer require magento/product-enterprise-edition=2.4.0 --no-update
composer update
During 'composer update' getting an error from the Magento module.
I have tried with included Magento keys in the auth.json file. But it's not worked. Any another solution for this error. How to resolve this.
The "http://xxrepo.xxx.com/dist/magento/module-ui/magento-module-ui-101.2.0.zip" file could not be downloaded (HTTP/1.1 404 Not Found)
Please let me know if anyone knows how to resolve this.
You don't need to run
composer require Magento/product-enterprise-edition=2.4.0 --no-update
You can use the below method to upgrade the commerce edition, eg if you want to upgrade to 2.4.3 then the below command will be used.
composer require "magento/magento-cloud-metapackage":">=2.4.3 <2.4.4"
--no-update -vvv
composer update magento/magento-cloud-metapackage -vvv
composer update -vvv
After this, you need to commit your changed files and merge them with integration or staging instances.

Magento Post Upgrade steps : 2.3 to 2.4

I have recently upgraded magento version from 2.3 to 2.4
WHat are the potential post upgrade steps for further process ?
Welcome to Stackoverflow, your question is not fully clear, please try to ask some specific question
There are no post-upgrade steps - the goal of upgrading should be a working system without any additional steps
To upgrade to 2.4 you need
Install and setup Elasticsearch
install MariaDB version compatible with Magento 2.4
Update Magento itself with composer
Run setup:upgrade command

i can't able to run composer install command under my /var/www/html/magento2

i am facing problem while setting up the magento server on Centos7 i have php 7.3 install in my centos ec2 instance
installed php 7.3.5, also tried to update composer using $composer update command it doesn't work
composer install
Magento 2 does not support php 7.3 as of yet. A significant numer of core modules specify the php versions they will allow. You will need to change your php version. See this link for the supported versions. https://devdocs.magento.com/guides/v2.3/install-gde/system-requirements-tech.html

Extension Manager is in offline mode. No TER connection available in TYPO3

I have installed TYPO3 Version 7.6.15 by using composer and also I am using the Xampp version 7.0.0. I have installed many extensions and activated them successfully at the backend of my TYPO3 page.
Now, I have installed the Ecodev/typo3-cms-speciality-distribution via composer. and i am trying to activate it from extension manager but it is giving me following error. Error
Now, I have no idea, what to do? at this link https://github.com/Ecodev/typo3-cms-speciality-distribution
it is written to deactivate EXT:fluid_styled_content, EXT:context_help, EXT:func, so i did, but still the same error. Any help will be grateful thanks.
Finally, i found the error, it is just because when we installed the speciality distribution package, we also need to install and activate all the other dependencies which are important for this package.
After installing them, this problem will resolved. As, i was using it via composer mode.
Thanks
