Workspace isn't accessible right after installing a plugin

[akurinnoy]

Describe the bug

After installing a plugin listed in "Che plugin" panel I tried to restart the workspace by click on the popup and confirming that in dialog window. Instead of the workspace-loader page I got server error.

Che version

• latest
• nightly
• other: please specify

Steps to reproduce

1. Click on "View" and then click on "Che Plugins"
2. In "Che Plugins" panel click on "Install" button in the first plugin.
3. Wait until plugin gets installed.
4. Click on the green rectangular with text "Click here to apply changes ..." on the top of "Che Plugins" panel and then confirm your intention in modal dialog window.
5. See the server error on the page.

Expected behavior

Workspace is loading and workspace-loader shows loading logs.

Additional context

@akurinnoy Before I get a chance to try that myself... Is there a workaround, or this results in completely unusable workspace?
Also you pointed you used latest version of che. Could you try with nightly if this bug still reproduces?

[akurinnoy]

@rhopp workspace works well if you refresh the page.

I made a mistake - pointed wrong version of Che. I got the bug on nightly version. Description is updated.

[rhopp]

Even the workaround is pretty simple (F5), this looks like a nasty bug. I would vote for fixing this in GA.

I have the same issue in Che on minikube

It looks something has changed on the backend. Now before refreshing the page plugin manager should wait a bit until workspace has been stopped completely.

Devfile I am using to create a workspace

Sometimes I get 404

I have changed this issue title because the workspace is restarted successfully but the user is redirected too early and the app is not ready yet.
