I have a very slow unstable network.

First Observation Running Locally

go get -u github.com/jinzhu/gorm

But if I run the same command outside the module directory, it can be completed in a reasonable time without any stdout.

Second Observation Running Remotely

go get -u github.com/jinzhu/gormgo.mod

go build
go get -u

My two questions:

go get -ugo get -u
go get -ugitgitcurlcurlwgetgo get -uerror: RPC failed; The remote end hung up unexpectedly; fatal: early EOF; fatal: index-pack failed;go get -u

Thanks a lot.

(Btw, if go get can use wget, it will work in my local environment. I never have any problems with wget and wget will finally complete the download after waiting for a long time. But unfortunately, wget is not a preferred tool by the current dev world)
