I have no idea why edg isn't getting found :(.

[Stephan T. Lavavej (StephanTLavavej)]

I guess the next step to investigate is to prepare a VM with the script, and manually try to invoke cl /BE and see what happens?

[Curtis J Bezault (cbezault)]

Yup that would do it. You could also fuss around with making commits to this PR to do some debugging.

[Alex Guteniev (AlexGuteniev)]

As there's p2 already, can you just try again with p2?

[Curtis J Bezault (cbezault)]

Sure

[Curtis J Bezault (cbezault)]

Same problem

[Curtis J Bezault (cbezault)]

Looks like the CoreIde component doesn't exist anymore and we're silently failing when we provision the machines.

[Stephan T. Lavavej (StephanTLavavej)]

To make investigations easier in the future, when command-line install fails like this, are logs emitted anywhere (or can we add an option to request them)? I guess we could reproduce this at will any time by attempting to install a nonexistent component.

[Curtis J Bezault (cbezault)]

I think the problem with this one is that we need to pass --quiet to the VS installer in order to make it run unattended but when that happens no logs or other indicators are emitted. All we could do is check the installed packages after the fact and make sure they match what we expect.

Also Lukasz notes that this is probably due to us using the Build Tools SKU and it was just working by luck previously.

Use command-line parameters to install Visual Studio - Error codes says:

Each operation generates several log files in the %TEMP% directory that indicate the progress of the installation. Sort the folder by date and look for files that begin with dd_bootstrapper, dd_client, and dd_setup for the bootstrapper, the installer app, and the setup engine, respectively.

and doesn't say that --quiet suppresses them. Are log files being emitted there? If so, could we make the script echo them?

[Billy O'Neal (BillyONeal)]

It doesn't matter if the script could echo them because we don't get any output from the script when run through Invoke-AzVmRunCommand

[Billy O'Neal (BillyONeal)]

(I debugged issues like this by running the script in a (local) VM)

Thanks for taking care of this update! I'll have to learn how to do the next one. 😸
