multipass launch/find fail when using PAC file (needs Qt 6)
Describe the bug
When running multipass launch or multipass find it fails because it can't retried a PAC script.
To Reproduce
-
multipass launch --verbose
mutipass fails with:
launch failed: Remote "" is unknown or unreachable.
Expected behavior MultiPass should have been able to download the needed files.

Additional context
Mac client is running Cisco AnyConnect.
Cisco AnyConnect tells the client to use a PAC file as shown by running scutil --proxy:
<dictionary> {
ProxyAutoConfigEnable : 1
ProxyAutoConfigURLString : http://wpad.example.com/wpad.dat
}
Note - I also have http_proxy and https_proxy set, but it looks like those are ignored.
@prbsparx the error message suggests the PAC URL (http://wpad.example.com/wpad.dat) is not reachable, can you confirm you can download the PAC file?
Looking closer at this, and trying some things out, I believe the problem lies in Qt, it's trying to load a url-escaped URL (http%3A%2F%2Fwpad.example.com%2Fwpad.dat). I was able to successfully use a static proxy with Multipass, but not through a PAC file (when the same PAC file worked fine in a browser).
Could you try setting a static proxy instead of a PAC file?

It definitely is from the network I was using.

I actually had run a function proxye that I wrote to configure my proxy variables... and noticed it didn't read those.
Cisco AnyConnect configures the proxy settings and I can't change them from my end. Our vpn admins would have to create a unique profile for me to test that.
I saw they already have a commit that will fix this and it's going to be included in Qt 6 supposedly.
What does that mean regarding timing for the issue actually being fixed?
Hi @prbsparx,

Right, the system wide preferences are used.

It will require us to switch to Qt 6 so not a "tomorrow" thing. We'll look into it for our next release, though.
I am also facing the same problem when trying to start the microK8s on multipass. Any update or workaround is much appreciated 🙏
@gkarthiks, I just remove the PAC temp. :(
Would it be possible to elaborate on how this workaround works? I'm facing the same issue

I use a macbook, and under Network -> Proxies I just uncheck the checkbox for automatic proxy configuration.
Hi all, Qt 5.15.3 was released recently and includes the fix for this. It won't make our upcoming 1.9.0 release, but we'll try and get it into the next one a number of weeks later.
New to Multipass. Downloaded version 1.11.1+mac. My company uses PAC file for determining the right proxy behind VPN. And I'm experiencing this issue. Maybe I missed it, but I did not see any fix or workaround described here. Any help is greatly appreciated.
@jojomgithub The workaround for now is to close your VPN and disable "Automatic Proxy Configuration" on your Mac. Make sure you save the previous setting before unchecking.
On your Mac, navigate to: Apple Menu -> Preferences -> Search for "Proxies"
This is fixed in the development version and will be in the 1.13 release.
