Hi,

Thanks for reporting. Can you also add the go.mod file which you are trying to check for the update?

[KenanBek]

@Dentrax also could you please specify how did you install it? With brew or go get. And in case of the second option, what is your local Go version?

[Dentrax]

Sorry, i forgot the add that informations. :)

I just installed it from brew
Go ver.: go version go1.13.6 darwin/amd64

Important info: There may be X more private repositories that it shouldn't be count or access for.

I tried to reproduce this problem with a test case, replacing the last 2 required with the private module I created now.

I got verifying github.com/ormanli/go-plus@v0.0.1/go.mod: github.com/ormanli/go-plus@v0.0.1/go.mod: reading https://sum.golang.org/lookup/github.com/ormanli/go-plus@v0.0.1: 410 Gone.

After this, I came across this issue, which describes the same. Since we are using go mod underneath to fetch updates, we don't have much to do now.

[Dentrax]

You can just ignore custom private modules, actually, which is fine for now, instead of throw panic.

[Dentrax]

@ormanli Even though i upgraded to ver. 0.1.1 with homebrew , still getting exactly same segmentation violation on same project and environment. :(

[ormanli]

I updated to v0.1.2 which solves panic. For private modules, I added a section to readme. Can you check if panic is solved?

[Dentrax]

Panic is solved but now getting another weird error: cannot register licenses from archive: open /home/runner/go/pkg/mod/github.com/google/licenseclassifier@v0.0.0-20200108231022-9dfa8d8474eb/licenses/licenses.db: no such file or directory

[ormanli]

It looks like build process is broken, I will try to fix as soon as possible.

[ormanli]

Hi, can you try latest version 0.2.1 ?

[Dentrax]

Looks like now fixed. :)

But i think you should improve the output log:

  github.com/afex/hystrix-go           | v0.0.0-20180502004556-fa1af6a1f4f5 | failed because of: no version
                                       |                                    | available

failed because of: no version available error occupies 2 lines, should be 1 think. Also colored output for updates should be fine :)
