Falta tree y errores de 'request duplicada' al presionar a Gerrit

Cuando bash presionar a gerrit, aparece este error:

Counting objects: 1276, done. Delta compression using up to 8 threads. Compressing objects: 100% (918/918), done. Writing objects: 100% (1276/1276), 235.23 KiB | 0 bytes/s, done.

En esta pregunta , se menciona el uso de git push --no-thin , pero eso también genera un error:

 Counting objects: 1276, done. Delta compression using up to 8 threads. Compressing objects: 100% (991/991), done. Writing objects: 100% (1276/1276), 741.02 KiB | 0 bytes/s, done.

Tengo una gran stack de compromisos que debo upload.

Ninguna de las soluciones en la pregunta vinculada ayudó. ¿Que debería hacer? ¿Qué significa el hash después del error del tree faltante?
