dbus upgrade fails on macOS (during port upgrade gnucash)

[kadorken@…]

after doing 'sudo port selfupdate' to 1.7.1, I proceeded to try 'sudo port upgrade gnucash' to 2.2.9. I previously had gnucash 2.2.8 installed (quartz version) on MACOS 10.5.6

When the installation got to dbus, the activation of dbus failed, possibly due to an earlier installation ? See the log excerpt that follows:

The port upgrade of gnucash proceeded to plug along, with period errors on other dependencies related to dbus not being properly installed.

Since that file is created by dbus during runtime, perhaps it can be deleted in a post-destroot phase (I have a copy of that file as well, and it wasn't installed by the port itself)?

[mcalhoun@…]

This file is created by calling dbus-uuidgen.
Prior to r49300, machine-id was created during post-activate and left in ${prefix}/var/lib/dbus/.
I thought it was better to create machine-id during post-destroot so it would be removed if
ever the user wanted to uninstall dbus.
I forgot that upgrading would be a problem.

The solution is to simply remove the old file in ${prefix}/var/lib/dbus/.
Everything should then proceed.

I will try to add some code to give a better error message.

[jmr@…]

Why not add a pre-activate to delete that file from $prefix?

[mcalhoun@…]

Adding reporter of duplicate #19236.

[mcalhoun@…]

Fixed in r49389.

[jmr@…]

Hadn't you better check that the file exists first, so new installs don't fail?

[mcalhoun@…]

Replying to jmr@…:

Hadn't you better check that the file exists first, so new installs don't fail?

Thank you for catching this.
The fix is fixed in r49391.
