Cannot install because signature is invalid or corrupted

Installing with Homebrew (El Capitan) yields following error message: Error: Failure while executing; '/usr/bin/sudo -E -- /usr/bin/env LOGNAME=ulrik USER=ulrik USERNAME=ulrik /usr/sbin/installer -pkg /usr/local/Caskroom/qlvideo/1.94/QLVideo_194.pkg -target /' exited with 1. Here's the output: installer: Package name is QuickLook Video installer: Certificate used to sign package is not trusted. Use -allowUntrusted to override. Where to put the -allowUntrusted command?

EDIT: found a temporary workaround. Unpack and repack the package with pkgutil in Terminal: pkgutil --expand package.pkg /tmp/package.pkg pkgutil --flatten /tmp/package.pkg package_fixed.pkg where "package.pkg" is the path to the downloaded (broken) package, "/tmp/package.pkg" is where said package will be temporarily expanded (in this case the /tmp folder), and "package_fixed.pkg" is the path where the new fixed package will be put. Expanding and reflattening a package will remove its signature, and unsigned packages are (as of now) installed without issues.

Hi, Is there a workaround for Monterey 12.5 (21G72)? Craig

[Ulrik54]

Unless pkgutil works in Monterey as well, I have no idea. I have never installed anything newer than El Capitan.

Hey, thanks for the reply, I will give it a try.

I was able to successfully install but preview is still not working after reboot. Might be a codec in the mp4 from a Sony FX3 that is not compatible Thanks for the help.

@craigalness could you please try to open it in mpv (the easiest way) and similar software?

Fixed in release 1.96

After the update, it no longer works on older systems (which is what OP and I were reporting issues on in the first place). Current solution using pkgutil still applies until a fix is implemented.
