Why is Gopkg.lock file deleted?

[ayushjn20]

Oh, that is a blunder. Apparently, dep ensure did not generate Gopkg.lock the file automatically if deleted. I was trying to update the dependencies as well as support for Golang v1.12.x. I had to make an empty lock file and then run dep ensure.

[ayushjn20]

I have re-commited changes, please check.

[apoorvam]

There are some new dependencies added here, like protobuf. Are those required?

[ayushjn20]

Yes. It's a lock file, that means it is automatically generated. I have updated all the dependencies by deleting the lock file first, then initializing an empty one followed bt dep ensure

• check if all package managers still work correctly, with new name

[ayushjn20]

Why is this check required now? I could not get it

* [ ]  check if all package managers still work correctly, with new name

[apoorvam]

@ayushjn20 Some of it references the name of the project/url. For example, https://github.com/leopardslab/homebrew-dunner/blob/master/Formula/dunner.rb#L14

It could be similar in all package managers. Github does redirect in some cases, but it's better to verify.

[ayushjn20]

I guess there is only snapcraft package manager is left, apart from Homebrew as of now.
@agentmilindu Could you please check on the snapcraft portal?
