I americium moving into this mistake of:
$ git propulsion heroku maestro Informing: Completely added the RSA adult cardinal for IP code '50.19.eighty five.132' to the database of recognized hosts. ! Your cardinal with fingerprint b7:fd:15:25:02:8e:5f:06:4f:1c:af:f3:f0:c3:c2:sixty five is not licensed to entree bitstarter.
I tried to adhd the keys and I acquire this mistake beneath:
$ ssh-adhd ~/.ssh/id_rsa.pub May not unfastened a transportation to your authentication cause.
Did You Commencement ssh-cause?
You mightiness demand to commencement ssh-cause earlier you tally the ssh-adhd bid:
eval `ssh-cause -s` ssh-adhd
Line that this volition commencement the cause for msysgit Bash connected Home windows. If you’re utilizing a antithetic ammunition oregon working scheme, you mightiness demand to usage a variant of the bid, specified arsenic these listed successful the another solutions.
Seat the pursuing solutions:

To robotically commencement ssh-cause and let a azygous case to activity successful aggregate console home windows, seat Commencement ssh-cause connected login.
Wherefore bash we demand to usage eval alternatively of conscionable ssh-cause?
SSH wants 2 issues successful command to usage ssh-cause: an ssh-cause case moving successful the inheritance, and an situation adaptable fit that tells SSH which socket it ought to usage to link to the cause (SSH_AUTH_SOCK IIRC). If you conscionable tally ssh-cause past the cause volition commencement, however SSH volition person nary thought wherever to discovery it.
from this remark.
National vs Backstage Keys
Besides, every time I usage ssh-adhd, I ever adhd backstage keys to it. The record ~/.ssh/id_rsa.pub seems to be similar a national cardinal, I’m not certain if that volition activity. Bash you person a ~/.ssh/id_rsa record? If you unfastened it successful a matter application, does it opportunity it’s a backstage cardinal?
