I have Magento Community 2.2. installed on managed VPS (Hetzner).
I am trying to install component and before installation it starts "Readiness check".
All checks out except for:

```
Check Component Dependency

We found conflicting component dependencies. Hide detail

For additional assistance, see component dependency help .

```

I don't get any details on error. 

**WHAT I HAVE TRIED**

I have followed instructions from here: <https://devdocs.magento.com/guides/v2.2/comp-mgr/trouble/cman/component-depend.html>

* I have run command for file permissions described here: <https://devdocs.magento.com/guides/v2.2/install-gde/prereq/file-sys-perms-over.html>
* I have tried with removing files `/var/.update_cronjob_status` and `/var/.setup_cronjob_status` and regenerating them starting Module Manager (probably previously known as Component manager)

POSSIBLE CAUSE
I was running installation of a module through composer and when asked for authorization (public and private keys) i have saved them in composer.json.
Since this is one of possible reasons listed in their documentation (changing of composer.json) all it says is to "edit composer.json" but it doesn't say how or what...
I have opened composer.json but I didn't find any keys there...

UPDATE
------

I have 2 locations for file `composer.json`:

* `\public_html\composer.json`
* `\public_html\var\composer.json`

Also have 2 locations for file `auth.json`:

* `\public_html\composer_home\auth.json`
* `\.composer\auth.json`

I appreciate help with this :)

**Sorry for updates, I am slowly remembering everything I did :)**

**I have tried to install this:** - Iazel\_RegenProductUrl - <https://github.com/elgentos/regenerate-catalog-urls>

**I have installed this:** - OlegKoval\_RegenerateUrlRewrites - <https://github.com/olegkoval/magento2-regenerate_url_rewrites> 

While installing through SSH I had some memory problems and got `Killed` in process.
I found a way to run commands again and installed 1 module listed above.

Module wasn't working as expected so I have tried to install one from Magento Marketplace <https://marketplace.magento.com/itcolony-seooverwrite.html>. This is where I got error with "Readiness check" and started to investigate on possible causes and solutions.

After that I checked `composer.json` and saw both modules (Iazel\_RegenProductUrl and OlegKoval\_RegenerateUrlRewrites) are listed in `require:` section so I deleted the line where `Iazel_RegenProductUrl` because I thought it caused problems (since install got killed).

Here it my `composer.json`:
