conflicting component dependencies in Magento 2.3.0

[marin_detchev]

I tried all of the above, but the problem persists.

This worked for me. 

This should be detailed as an error message.

How did you figure this out?

[Stainless007]

Make sure and update it in the local php values in .htaccess and .user.ini

I was searching as well, proposed solutions didn't work. Turned out I was on PHP 7.3.17 and I switched back to 7.2 (had to anyway, because a need module didn't work on 7.3.x)

Maybe it 'll help someone.

OMG, This solution is the best after researching 8 hours. What I did was just editing the .htacess in root htdocs folder from 

php_value memory_limit 756M

to 

php_value memory_limit 3G

And it Works!

@wylan_swets1  Yes, I confirm that this general error "conflicting component dependencies" in the setup wizard if not related to actual conflicting component (You can assume that if no details about the components is provided in the error message) is related to the PHP memory limit. 

But to make this answer complete in addition to changing the memory limit in the server php.ini and ".htaccess" file. You need also to change it in the ".user.ini" file that is located in the root web directory of your Magento installation.

The Apache server based on the selected configuration (in case of FPM for example) may load the "memory_limit = 2048M" value from this file ".user.ini".

As @technoswift said, I had to also change memory_limit in the .user.ini file.
