Magento2: 2.1.3 - Web Setup Wizzard - Component Manager - spinning wheel (still doesn't work)

[commcad]

Preconditions

1. Mage 2.1.3
2. NGINX, PHP 7.0.8-0ubuntu0.16.04.3

Steps to reproduce

1. Login to backend
2. Go into > System > Web Setup Manager
3. Click on Component Manager

Expected result

1. Forgot what this feature is meant for, seen it last working back in March 2016 I think.
2. I think its for installing module purchased from the Marketplace. Thankfully I haven't purchase any, yet anyway. Wish I could in all honesty :/

Actual result

1. Spinning wheel, caption saying "Please Wait"
2. Had this "Please wait" for nearly a year now, or since 2.0.6 if memory is good

( the most epic wait ever!)

I'm seeing 20 minute page load times for the page itself, however, it does eventually load. I would say this makes it practically unusable though, as the admin session seems to timeout waiting on the page load to occur.

Experiencing the same issue. In fact the whole "Web Setup Wizard" is kind of useless. Updating Magento makes no sense either. Why did this all get so complicated and instable?

I'm having the same problem, but with a freshly installed instance of Magento 2.1.5
Is there solution to this at all?

@AvanorHealthcare We moved everything into composer installs using marketplace credentials. Almost every popular module now offers the ability to install the module through the composer.json file instead of using the web install wizard. Personally, I'd recommend going that route

[AvanorHealthcare]

@JamesonNetworks Funnily enough, that's exactly what I've been doing. It just seems daft to have to go through the grind of doing a command line install when there's supposed to be an easy, built-in function linked directly to Magento Marketplace.

@AvanorHealthcare, when you say you use the composer.json, can you please tell me how you used this file? Is there a UI, or did you run a command using this file?

Thank you

This is all from the commandline and gets committed with the repo

I have fixed this issue by following below steps:

• Open /setup/index.php/componentGrid/components in new tab
• It showed me actual error, in my case it was last extension installed through composer.
• I have removed that from composer
• After updating composer, the error goes away.
