No estoy seguro de por qué soyunable to checkout una rama en la que había trabajado anteriormente. Vea los comandos a continuación (nota:co es un alias paracheckout):

ramon@ramon-desktop:~/source/unstilted$ git branch -a
* develop
  feature/datts_right
  feature/user_controlled_menu
  feature/user_controlled_site_layouts
  master
  remotes/origin/HEAD -> origin/master
  remotes/origin/develop
  remotes/origin/feature/datts_right
  remotes/origin/master
ramon@ramon-desktop:~/source/unstilted$ git co feature/user_controlled_site_layouts 
error: pathspec 'feature/user_controlled_site_layouts' did not match any file(s) known to git.

No estoy seguro de lo que significa, y parece que no puedo encontrar nada que pueda entender en Google.

¿Cómo pago esa rama y qué puedo haber hecho para romper esto?
