The package appears to be out-dated due to updated version of devtunnels. Here's some steps to update incase you want to use and install this, by updating the checksums:

devtunnel-cli-bin

Arch Linux package for Microsoft Dev Tunnels CLI client.

Installation

makepkg -si

Updating Checksums

If you encounter a checksum validation error like:

==> Validating source_x86_64 files with sha256sums...
    devtunnel_x86_64 ... FAILED
==> ERROR: One or more files did not pass the validity check!

This means the remote binary has been updated but the PKGBUILD has outdated checksums. To fix:

1. Generate the new checksum for the downloaded binary: bash sha256sum devtunnel_x86_64

2. Update the sha256sums_x86_64 value in PKGBUILD with the new checksum.

3. For ARM64 systems, also update sha256sums_aarch64 if needed: bash sha256sum devtunnel_arm64

4. Run makepkg again: bash makepkg -si

Notes

• This package downloads the latest version from Microsoft's servers regardless of the pkgver setting
• The binary cannot be stripped due to bundle corruption issues
• Requires libsecret dependency for proper functionality%

I've just disowned it, if you want to go ahead and adopt it. As far as I can tell, there's no easy way to tell when upstream gets updated, other than to just periodically check the signatures

You may want to write a script to automate that process.

This package needs updating as the signatures no longer match with the latest binary.
