My Bitbucket settings show my username as X, which is the same as my OSX userID. But when I do an "hg fetch", my ~/.ssh/id_rsa seems to be ignored and I'm prompted for the password of user X2. X2 is similar to the concatenation of my First and Last Names in Bitbucket account settings.
How can I get "hg fetch" to use my private key and stop nagging me for a password?
Update: It seems that part of the issue is that localCloneDir/.hg/hgrc contained
[paths]
default = https://X2@bitbucket.org/
But I'm still prompted for the password (and I recently removed all prior keys on BB, regenerated my private and public keys, and uploaded these, so there is no disagreement between public and private).
