electron-updater fails to install update on MacOS

[robertpatrick]

• Electron-Builder Version: 22.13.1

• Node Version: 16.13.0

• Electron Version: 13.5.2
• Electron Type (current, beta, nightly): current

• Electron-Updater Version: 4.3.9

• Target: MacOS (default)

We are trying to release our application using electron-updater. Everything works on Windows (other than we are also seeing the behavior described by #6329) and Linux but our MacOS app is failing to install the update. The relevant section of the log looks like this:

The directory /Users/rpatrick/Library/Caches/com.oracle.weblogic.wktui.ShipIt is empty so the error message seems to be misleading. I have no idea why this is failing but I am down to the last week before our release so any clues would be very welcome!

Hi there!
Would you mind trying with [email protected]? There's been a lot of changes since 4.3.9, and having 4.6.1 as a base version to work from will help.
Regarding the empty directory. Did this file at least exist or did the download/pipe fail entirely? /Users/rpatrick/Library/Application Support/Caches/wktui-updater/pending/WebLogic-Kubernetes-Toolkit-UI-0.8.13-mac.zip

@mmaietta i will try with the newer version. The file is downloaded to ~/Library/Application Support/Caches/wktui-updater/pending/. I see three files created in the ~/Library/Caches/app-bundle-id> directory but nothing in ~/Library/Caches/<app-bundle-id>.ShipIt directory.

I was able to figure out how to fix the problem. Due to the process requirements of my employer, we were unable to use electron-builder to sign the app and we cannot use the electron-publisher functionality to publish the release due to lack of support for a proxy server. I tracked down a couple of problems related to permissions on the files and a missing zip.blockmap file not being attached to the release. Addressing these issues resolved the problem--even with the 4.3.9 version.
