Install failure due to "internal error in Code Signing subsystem"

[joshenders]

xcode-install version: xcode-install-2.4.4 macOS version: 10.13.6

We're experiencing intermittent install failures when running the following command:

xcversion install --verbose 10

Expected ouput:

/Applications/Xcode-10.app: accepted
source=Apple System
%
Xcode 10.0
Build version 10A255

Actual output:

/Applications/Xcode-10.app: internal error in Code Signing subsystem
%Error returned: <error: 0x107f56cb0> { count = 1, transaction: 0, voucher = 0x0, contents =
"XPCErrorDescription" => <string: 0x107f57020> { length = 22, contents = "Connection interrupted" }
}

Incidentally, the exit status after a failure is 0 which indicates a separate issue, as as Xcode does not get installed and so this should exit with a status greater than zero.
