I too wanted to set up the snowflake proxy on my fresh dietpi install. Ran into some difficulties with the go install via dietpi-software. It seems that like there could still be something amiss with the Go paths set via dietpi-software
I manually had to add the GOPATH to my .bashrc. This did work when running go directly from the cli. However, when trying to build the snowflake proxy, go was not found on my system.
My current workaround is to uninstall go and install golang via apt.
– Edit
I set up a clean install once more and installed go via dietpi-software. Sadly no bueno on the paths being added on install.
