@Amulyam24 Thanks for reporting this issue. I am using Ubuntu 20.04 with go 1.22.1 and I cannot reproduce this issue. What is the version of the go binary you are using?

Hi @qweeah, with go 1.22 it works.

What is the version of the go binary you are using?
1.21.3

[qweeah]

The error is expected, you need to upgrade go to 1.22.* and then compile oras. IMHO, no change need on ORAS side.

Updating the toolchain patch version works - #1351
and this won't need updating the go version as it is handled internally by downloading the desired version for the build
Is it not the desired approach?
Reference - golang/go#66175
