Composer stuck on Updating dependencies Fixed
You should try this
//Installation COMPOSER_MEMORY_LIMIT=-1 composer install -vvv //Updating COMPOSER_MEMORY_LIMIT=-1 composer update -vvv -vvv will display progress.
Add "-vvv" at the end to running command in verbose mode and it will display what files are being downloaded.
Add ''COMPOSER_MEMORY_LIMIT=-1" so command won't run out of ram.
Hope it helped
