I just got my new Shark Jack in the mail today, and when I was playing around with it I realized it didn't have curl. I saw on the guide that it comes with opkg to install extra packages, but it seems to reference the 18.04-SNAPSHOT version in the OpenWRT repositories, which does not exist. I started looking through the packages, found some dates, and looked for the version that has "Last Modified" dates similar to the Shark Jack version, and settled on 18.04.1. However, I'm not sure if this is correct. So far, it's worked for libustream-mbedtls, ca-bundle, ca-certificates, nano, and curl, and seems to be fine. Can someone confirm this? Ideally, I'd like to see an official firmware update with fixed URLs, but this seems to work for now.
Thanks!
