Using Eclipse EGit 1.2.0.201112010521 I was in the Git Repo view and right-clicked on eclipse.platform.ui>Branches>Remote Tracking>origin/master. I selected "Create Branch" and filled in my local branch, pwebster/bugMenuTests. When I clicked OK, I got the exception at the end of the report. But I checked: .git/config exists, is writable, and contains correct new entries for the branch that was just created: [branch "pwebster/bugMenuTests"] remote = origin merge = refs/heads/master rebase = true I also can no longer switch branches from EGit to a regular branch, I get Caused by: java.io.IOException: Cannot lock /opt/pwebster/git/R42/eclipse.platform.ui/.git/index at

from the command line I got: If no other git process is currently running, this probably means a git process crashed in this repository earlier. Make sure no other git process is running and remove the file manually to continue. Removing the index.lock allowed me to checkout branches once more. PW

Also see bug 360141.
Fix proposed for the secondary problem: index is locked after failed branch action http://egit.eclipse.org/r/4869
(In reply to comment #3) > Fix proposed for the secondary problem: index is locked after failed branch > action > > http://egit.eclipse.org/r/4869 This Fix is merged but this bugzilla is still in NEW state. Is this just in this bug the case or are there more bugs open which are fixed in reality?
this fix was merged as 0a84ad2d2ac8153d06564895279ab4fd11ef0e80 in April 2012
