While getting the sandbox up and running I ran into some issues due to the rust version that seemed consistent with rust-lang/cargo#8258. It took a few tries due to stalling, but I eventually successfully installed rust stable (1.45.2). I then tried to install capsule, but ran into linker issues
LinkerSegfault.log
I got around this issue by updating the container, which allowed me to get around the linker segmentation fault.
Recommend updating Rust to current stable (1.45.2) and updating container image
