I get the following error when trying to amend a commit (same if I try to make a new commit):
1 git … commit --amend *ERROR*: Terminal type "dumb" is not powerful enough to run Emacs error: There was a problem with the editor 'emacsclient -t'. Please supply the message using either -m or -F option.
It was working earlier, the only thing I remember changing was trying out magit-gerrit. I removed that since and still doesn't work.
emacsclient -t works from the command line.
