That is one of the more generic error messages I've seen. There's nothing in the screenshot that helps narrow down the specific cause, but it could be hardware related (HDD/SSD issues, RAM issues), software related (corrupted file being downloaded, issues with the existing OS) or something else not directly related to your machine.
I can see a couple of ways to try to resolve this. The easiest way is via the process listed here (Macworld). However if that still does not work, you can always try restoring from another Mac using DFU mode and the Apple Configurator 2 app.
Yes, I see have seen the same error when I am trying to install or update the OS on a mid-2015 Air that had been exposed to moisture. Eventually, after 2 or 3 tries, the OS will install or update.
It can't the SSD because it happens with a working SSD from another Air; therefore, I think there is something on the main board that is flaky.

The built-in diagnostics are not as thorough as the diagnostics run at the Apple Store. The first set of tests are run using Apple diagnostics available to the frontline reps. If this set of tests cannot determine the fault, the techs in the back have another set of tools available. The techs will also check for moisture and physical damage after removing the bottom cover.
