@johnmichaloski ,Thanks for posting this issue.

It seems that your error is related to MSYS2-packages. According to the official comments, it may be related to the old version. You can try to update the version.
The following issue is the same as your error and has been successfully resolved, you can refer to it

Ok thanks. I played around but couldn't get it to work - there was no windows compatible pacman-key and I'm really a newbie to a lot of this stuff. Wasn't looking promising. Plus vcpkg,msys2, and pacman are embedded deeply in the MS deployment of ROS and since there is no pacman-key, so I will ask the MS ROS for windows git issues for help.

Okay, I will continue to track and investigate the solution

@johnmichaloski ，You can update vcpkg and try again. If it doesn’t work, you can try to clone vcpkg again, which may solve your problem.

@johnmichaloski ,Is this still a problem for you？

So, reinstalling vcpkg did install libxml2.

Steps to Install libxml2

Problem: ROS1 used old open source packages in the bundled vcpkg. So had to download and clone vcpkg that had the latest packagers for zlib (David Macek with signing key 0x9078f532) required by libxml2, which is the package used in a ROS1 workspace.

Step 1: Clone the vcpkg repo (From vcpkg windows install instructions)

cd C:\opt
git clone https://github.com/Microsoft/vcpkg.git

Make sure you are in the directory you want the tool installed to before doing this.

Step 2: Run the bootstrap script to build vcpkg

.\vcpkg\bootstrap-vcpkg.bat

Step 3: Setup use of VC 2019 community

Previously had downloaded VC 2019 community to be used aa command line build tool for ROS1. Note: had bundled ROS1 and VC 2019 in PATH environment variable. So created separate command terminal: and then
C:\Windows\System32\cmd.exe /k "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\Tools\VsDevCmd.bat" -arch=amd64 -host_arch=amd64
Just assumed it was needed.

Step 4: Install libxml2

C:\opt\vcpkg>.\vcpkg install libxml2
This worked with the new packager download hash credentials.

Packages installed in C:\opt\vcpkg\installed\x86-windows Have not tested.
