Can't update single package with go modules

I have 2 projects with go.mod in root directory. One is https://github.com/Gohryt/Impossible.go Next one is something that require impossible in go.mod

I made simple commit with renaming a pair of variables. My second module needs in this variables and I renamed it there too. But I didn't find any command like go mod update, only go mod tidy and I can't use new names of variables. I tried tidy, but it made nothing. In some guides from internet i found that i should rename version in go mod and then tidy should work, but it has name like v0.0.0-20210101010359-ec9f21b49366 and i really can't guess what is new name like.

Is there any normal way to update module or i should use old version of dependency every time after first usage?

I tried name version with latest, but go mod tidy did nothing again.

If module A requires module B, and your program requires both... You will want to make sure module A requires the correct version of module B. Here's some things I end up doing often to keep everything synchronized how I want it.

To upgrade modules, first enter the repository...

upgrade all modules:

go get -v -u ./...

upgrade a certain module to latest commit:

go get -v -u github.com/user/repo@master

upgrade a certain module to a certain branch:

go get -v -u github.com/user/repo@develop

and then type this at the end:

go mod tidy

commit the changes to your repo, and consider a new tag.

git commit -v -a

git tag v0.0.2

git push origin branch --tags

Then, back to your program repository.. and do the same steps, but make sure your imported modules say the right tags when you run that -v -u command.

And make sure that your go.sum, go.mod files doesn't have extra stuff from old modules.

I would do go get -u "{package_name}@{git_commit_hash}"

for e.g., go get -u "gopack@1fdd851775f2bc513003d46850c56cb77d8e297b"

-u flag is to update an already installed package.
