I am using symfony4.4

$composer update

curl error 6 while downloading https://flex.symfony.com/versions.json: Could not resolve host: flex.symfony.com

There appeared error and I googled around and found this article.

Error with Symfony Flex: You have misconfigured DNS resolver(s)

I tried this,

$composer update symfony/flex --no-plugins --no-scripts

However error again.

Cannot update only a partial set of packages without a lock file present. Run `composer update` to generate a lock file.

I need to do composer update to generate lock file but composer update shows the error.

It's eternal loop.....

Could you help some hint??

This is nothing you can fix right now because

$ host flex.symfony.com
Host flex.symfony.com not found: 3(NXDOMAIN)

which simply means there's no such host as flex.symfony.com known to DNS. It might be their delegation problem or anything like that but this is not what you are able to fix.

In future you can always use services like https://isitdownrightnow.com to see if this is your local DNS issue or affects everyone:
