cURL (pronounced like “curl”, /kɜːl/) is a computer software project providing a library ( libcurl ) and command-line tool ( curl ) for transferring data using various network protocols. The name stands for “Client URL”
I think julia uses libcurl under the hood for downloading files. I’m not sure why you’re getting such a cryptic error message but I’m guessing you were just having some connectivity issues and they went away after restarting.
That would be great if it’s true. When I got this mess on the Intel machine I got in so deep that I had to download .julia/environments/v1.6 from another computer before I could sort it out. The ARM machine showed the same message 30mins later, but did not cause any problems.
