appcast.xml only announces ARM builds for macOS, breaking updates on Intel Macs

[meineerde]

Description

The appcast.xml file at https://borgbase.github.io/vorta/appcast.xml which is used by the Sparkle update framework currently announces only the ARM builds for Vorta 0.10.0 and 0.10.1. This breaks Vorta on Intel Macs when the automatic update runs.

The appcast should also announce Intel builds to allow Sparkle to update the app with the right architecture. Alternatively, Vorta could also be distributes as a universal app, containing both ARM and Intel binaries.

A third options could also be to use separate appcast.xml feeds for each architecture, each pointing only to the release files in the current architecture.

I'm aware this isn't optimal, but I couldn't find a way to server different architectures. Some people suggest to set up a webserver and separate by user agent, which has the architecture (?).

I also don't know how to make a universal app with Pyinstaller, but if someone else knows, just go for it. Workflow used is here: https://github.com/borgbase/vorta/blob/master/.github/workflows/build-macos.yml

Couldn't it be possible to update the generate_appcast.py script in the gh-pages branch of this repo (which generates the appcast.xml files on https://borgbase.github.io/vorta) to accept an additional argument for the architecture of the binaries and use this to generate more than the two current files, e.g.:

• appcast-arm.xml
• appcast-amd64.xml
• appcast-pre-arm.xml
• appcast-pre-amd64.xml

You could then configure the right URL in

vorta/src/vorta/updater.py

Lines 33 to 36 in 6bec467

	if SettingsModel.get(key='updates_include_beta').value:
	appcast_nsurl = Cocoa.NSURL.URLWithString_('https://borgbase.github.io/vorta/appcast-pre.xml')
	else:
	appcast_nsurl = Cocoa.NSURL.URLWithString_('https://borgbase.github.io/vorta/appcast.xml')

and

vorta/package/vorta.spec

Line 14 in 6bec467

APP_APPCAST_URL = 'https://borgbase.github.io/vorta/appcast.xml'

based on the current architecture of the running app (which I guess can be somehow obtained).

Unfortunately though, with the status quo, the sparkle updates are fully broken for Intel Macs and will result in a broken installation on each and every update again which must then be manually fixed with a manual re-install of the app using the right architecture.

To anyone who is asking themselves how to fix this: Just update using homebrew or reinstall it from any othe source. Seems like it's only the auto-updater that installs the silicon version.

Download the right architecture from the release page – Intel or Arm.
