ngrok v3 introduces breaking changes.

Check https://ngrok.com/docs/guides/upgrade-v2-v3 for the upgrade instructions.

Note to self/future maintainers, this software only provides official downloads for an old release. The package itself then tries to update itself using 'equinox'. To find out the real download url, I use this script get_download_info:

#!/bin/bash

exec http -b https://update.equinox.io/check \
    'Accept:application/json; q=1; version=1; charset=utf-8' \
    'Content-Type:application/json; charset=utf-8' \
    app_id=app_goVRodbMVm \
    arch=amd64 \
    channel=stable \
    current_sha256=1aaccea9c0668d97f19095636b2f4fca033fb8d9f7fc37241a013f4f1fa48bb3 \
    current_version=2.2.8 \
    goarm= \
    os=linux \
    target_version= \
    "$@"

You need to call it with the different architectures:

get_download_info arch=386
get_download_info arch=amd64
get_download_info arch=arm
get_download_info arch=arm64

ngrok TCP isn't working, not sure why but in the past it worked fine. Perhaps it was the latest update, I'm not sure but maybe someone else needs to test it just to confirm it's not only my machine.

Since equinox hosts any package, it's actually very difficult to check the PKGBUILD to ensure you're installing legit software, and not any random exe.

I would always cross-check the binary against https://dl.equinox.io/ngrok/ngrok-v3/stable/archive

(for me the easiest is just to open the developer tools for the website and ctrl-f find the identifier).

For example, the current PKGBUILD (as of 3.10.1) contains this line: source_x86_64=("https://bin.equinox.io/a/81d5kzodW8G/ngrok-v3-3.10.1-linux-amd64")

but I cannot find 81d5kzodW8G in the ngrok-v3 website link. Therefore, I have locally patched it by running these steps:

Edit the PKGBUILD (I removed all the other flavors besides x86_64 to make my life easier. Replace the source with source_x86_64=("https://bin.equinox.io/a/gzCri6c7dA3/ngrok-v3-3.10.1-linux-amd64.tar.gz")

Run makepkg -g to generate the sha256 sums and replace those in the PKGBUILD as well. Finally, fix the .SRCINFO with makepkg --printsrcinfo > .SRCINFO

@brenekh it would be really appreciated if you could convert your process to use the download files that are on this page: https://dl.equinox.io/ngrok/ngrok-v3/stable/archive so we could easily audit them. Thank you!

Just to add: I'm not accusing anyone of maliciousness here, just an abundance of caution.

Diffing the file in PKGBUILD (https://bin.equinox.io/a/81d5kzodW8G/ngrok-v3-3.10.1-linux-amd64) versus the one inside https://bin.equinox.io/a/gzCri6c7dA3/ngrok-v3-3.10.1-linux-amd64.tar.gz and they are the exact same.

Since the server where the package is downloaded does not support resuming it would be best to first clear the partially downloaded files. (using yay)

ngrok v3 introduces breaking changes.

Check https://ngrok.com/docs/guides/upgrade-v2-v3 for the upgrade instructions.

I see that pkgbuild contains the following sha for amd64: 218d267cd1195334718bafac14bfdf1c19dc95dcf8a24aaa6a1383c21dc86e76

Searching for this in https://dl.equinox.io/ngrok/ngrok/stable/archive, gives me no results. Any reason for that ?

As per https://dl.equinox.io/ngrok/ngrok/stable/archive, the newest version is 2.3.38. (Even the script in your pinned comment gives the same thing.)

I just scanned the 64bit binary that this package installed and VirusTotal comes back clean: https://www.virustotal.com/gui/file/c930d52595169da874d201914b09b4cc779f536d7887eed90196aa3b40b4eafb/detection

Might be nothing, but virustotal reported one detection on v2.3.35: https://www.virustotal.com/gui/file/1fdd1c057c3c31044400ef6ade20ad3f10bce415ad33ccfb4bc2fd83bb36f62f/detection.

If I download the official zip from https://dashboard.ngrok.com/get-started/setup I don't see the same thing: https://www.virustotal.com/gui/file/1761f150c5e1d210e8148a863441af4bf0f0ae413d205fdb3ce9db4a3454d504/detection

Despite the app claiming an update is available, there is no new version available on the download page; or via the update script I jury rigged up.

The download url can be found at https://dl.equinox.io/ngrok/ngrok/stable/archive
