Installation failed, check internet connectivity or proxy

[TBT]

I've noticed this in Nagios 5.2.5, 5.2.6 and 5.2.7, when using the WebGUI to Install Updates for Components, an error message "Installation failed, check internet connectivity or proxy settings." occurs even though installation completes successfully. This error message isn't present when following the same process with installing updates for Config Wizards.

Please advise.

Thanks for letting us know. I replicated it on my end, and filed a bug report, ID #8271.
