Hi Guix, I use a local git repo with branch that I specify in channels.scm. My usual workflow is: 1. rebase on origin 2. guix pull This stopped working with the following error: Updating channel 'guix' from Git repository at 'file:///home/john/projects/guix/.git'... guix pull: error: aborting update of channel 'guix' to commit 1444040933ac35b967720288dc30ed70e5481ed3, which is not a descendant of 57518fc7bf1efc899c0dabaa76685a319661f8e4 hint: This could indicate that the channel has been tampered with and is trying to force a roll-back, preventing you from getting the latest updates. If you think this is not the case, explicitly allow non-forward updates. After removing $HOME/.cache/guix I get the following error: guix pull: error: Git error: object not found - no match for id (57518fc7bf1efc899c0dabaa76685a319661f8e4) Many thanks, John
