same problem

[ReHoss]

7 months later I still have face the issue with the last version of gh (gh version 2.74.0-19-gea8fc856e (2025-06-09))

EDIT: @HiddenMachine3 @drienkop @GTazz

gh was installed with snap on my machine. snap isolates programmes, thus no call was made to any clipboard programme. Installing gh by following the official recommended instructions (no apt either, since it installs a 2022 version) solved the issue. (Issue resolved with the support of ChatGPT).

I'm glad to hear that the issue is resolved, @ReHoss! and sorry this issue didn't get triaged by the team. 🙏

However, please note that gh is not officially shipped as a Snap package, and we explicitly advise our users about this. There's a community maintained package, but as you mentioned it has problems with strict confinement.

@HiddenMachine3, may I ask if the @ReHoss's solution worked for you?
