The Trezor Suite update progress bar is stuck on Linux.

[Ondra-Zik-SL]

Describe the bug
The update progress bar is stuck on Linux, showing 0.0 B / 0.0 B the entire time the update is being downloaded. After a while, depending on your connection, the update is completed, and you can restart Trezor Suite.

Info:

• Suite Version: 24.8.3 updating to 24.9.2
• OS: Ubuntu 24.04, Endeavour OS(rolling release)

How to reproduce

1. Open Trezor Suite AppImage version 24.8.3.
2. Start the update process and accept the update to version 24.9.2.
3. Observe the stuck progress bar.

Expected behavior
The progress bar should reflect the correct status of the downloaded data.

cc @peter-sanderson this may be connected to the recent changes in auto-update in Electron

I just tried the autoupdate and it is still an issue, unfortunately.

I think this issue is not related to any recent changes we made and it was there before.

I will definitely look into it, but it would be probably trickier...

Seems related:

• download-progress event not firing electron-userland/electron-builder#8659
• electron-updater: download-progress event not firing electron-userland/electron-builder#7235
• download-progress and update-downloaded events not firing with Electron 12 electron-userland/electron-builder#5800

It is very interesting, that in case I start with tor and then turn it off, it start to work and progress is shown gradually.

In some issues they mention that the problem is missing Content-Length header. But we have it.

Whet I force it (I changed the source code in node_modules of the Electron Updater) to use full download it works. 🤔 🤔 🤔

(It logs: Cannot download differentially, fallback to full download)

This is the real reason why it works when switching Tor (it raises exception that triggers this flow)
