Corrupt extention manager after installing Amasty Extention

[Aristan]

@CKENT, thanks so much. This is exactly what I needed.

I was having the same issue and I contacted Amasty concerning it. The message I got was not exactly the most helpful. (And a fresh install was NOT an option.)

"I`m afraid we do not have any possibility to check this issue. The only thing I can recommend you here is installing the extension via file uploading to the server or via composer."

Which makes no sense since I told them the extension was working fine and was installed manually. (We attempted to install via composer at first but it never could get connected.)

Hey there! 

Thanks for letting us know. We understand this is very frustrating. 

However, there are two possible ways to resolve the Wizard fatal error:

Way #1:

1. Please, connect to the server via SSH and navigate to the Magento root folder;
2. After that run the next command: COMPOSER_HOME=var/composer_home/ composer update
It will ask for your account information. Fill it in and complete the command.

Once it's done, the Wizard will work, however, the load time will be increased.

Way #2:

Another solution is to temporarily delete our repository from composer.json:
1. Please, connect to the server via SSH and navigate to the Magento root folder;
2. Run the command: composer config --unset repositories.amasty

Please, keep in mind it is a well-known issue and both our and Magento teams are working on solving it.

"Please, keep in mind it is a well-known issue and both our and Magento teams are working on solving it."

So it's a well known issue with two possible solutions, but I got "I`m afraid we do not have any possibility to check this issue." and told to reinstall from scratch as a response?

You can create a auth.json in your Magento root to authenticate against the Repositories.
Content should look something like this:  

{
    "http-basic": {
        "repo.magento.com": {
		username": "MAGENTO_PUBLIC_KEY",
		"password": "MAGENTO_PRIVATE_KEY"
        }
        ,"composer.amasty.com": {
                "username": "AMASTY_PUBLIC_KEY",
		"password": "AMASTY_PRIVATE_KEY"
        }
    }
}

This fixed the Problem for me.

Just wanted to let people know I tried this and it worked perfectly for me, you have to do have both, one for Amsty and one for Magento.

This works but you need to add a " before username - syntax error

Is there a way to fix this without having to reinstall the Magento?
