I think we just jumped threads. I’m still getting familiar with using this list. Cédrick just posted this I think in response to my exception report: http://forum.world.st/file/t372658/Screen_Shot_2020-05-12_at_2.png

I just had a quick look. This is cool. I might be missing a use case where I dit a previous fork and I want to use it later in time. I think that’s nice to cover this use case. Do you sync your fork on github ? From iceberg ? Or maybe no sync is possible ?

Cheers, Cedrick

Assuming that is true here is my response: I have not done any syncing yet. I created an empty github repository and was trying to add that to Iceberg when this exception. There is virtually nothing in my github repo: Https://github.com/MichaelKentBurns/FredsLunch-Pharo-iceberg “trying to use iceberg to coordinate with GitHub repository“
