Comment:
@classabbyamp appreciate you want to help. Unfortunately, it's not the path.
For reference the proper procedure requires two separate commands:
```
xbps-rindex -a /var/cache/xbps/pkg-1.0_1.xbps
xbps-install -R /var/cache/xbps/ -f pkg-1.0_1
```
as explained here: https://docs.voidlinux.org/xbps/advanced-usage.html?highlight=xdowng#via-xdowngrade

 **strace results for this issue follows shortly in my next comment.**
