I have been down this rabbit hole for literally weeks trying to deploy our companies app...
after running the tauri action I have to run ssl.com code signer on the installers, then re zip them, then sign the zip file to allow the updater to work with the signature.
However, when i run the npm run tauri signer sign ... it produces a new signature that needs to be added to latest.json. It seems like I am just redoing everything the tauri action already did.
If anyone has successfully achieved signing and functioning auto updates with a windows app via github actions PLEASE share your workflow or at least the details of your implementation. This is all inside my github action workflow so testing is punishingly slow as I have to wait for each change to run on github servers...
