This can be related to this: cosmos/ledger-go#4

Thank you @julienrbrt, that looks promising.

I just tried to replace ledger-go in gaia by adding a replace rule in go.mod:

replace (
	github.com/cosmos/ledger-go => github.com/empowerchain/ledger-go v0.9.2
)

make install runs without an error, this is the output:

--> Ensure dependencies have not been modified
all modules verified
go install -mod=readonly -tags "netgo ledger" -ldflags '-X github.com/cosmos/cosmos-sdk/version.Name=gaia -X github.com/cosmos/cosmos-sdk/version.AppName=gaiad -X github.com/cosmos/cosmos-sdk/version.Version=main-23a5a293a5e53eaf08bc4c9f099b658ad1ead080 -X github.com/cosmos/cosmos-sdk/version.Commit=23a5a293a5e53eaf08bc4c9f099b658ad1ead080 -X "github.com/cosmos/cosmos-sdk/version.BuildTags=netgo ledger," -X github.com/tendermint/tendermint/version.TMCoreSemVer=v0.35.6 -w -s' -trimpath  ./...

I think it's not using the forked version though. How can I force gaia to use github.com/empowerchain/ledger-go?
I'm not very familiar with golang, sorry.

[julienrbrt]

It does use the fork, but not with the right version: it uses a tag that does not contain the fix.
Try with github.com/cosmos/ledger-go => github.com/empowerchain/ledger-go v0.9.3-0.20220531092147-dab46ea76974 instead.

[felsd]

Thanks, it's working now.

Thanks for resolving this issue @julienrbrt !
@felsd can you confirm which version of gaia you're impacted by? are you working off of main or the v7.0.x family?

[felsd]

@okwme On the main branch.
