Question & Answer :
I had a repository that had any atrocious commits connected it (D, E and F for this illustration).
A-B-C-D-E-F maestro and root/maestro
I’ve modified the section repository particularly with a git reset --difficult. I took a subdivision earlier the reset truthful present I person a repo that seems similar:
A-B-C maestro \ D-E-F old_master A-B-C-D-E-F root/maestro
Present I wanted any elements of these atrocious commits truthful I cherry picked the bits I wanted and made any fresh commits truthful present I person the pursuing domestically:
A-B-C-G-H maestro \ D-E-F old_master
Present I privation to propulsion this government of affairs to the distant repo. Nevertheless, once I attempt to bash a git propulsion Git politely offers maine the brushwood disconnected:
$ git propulsion root +maestro:maestro --unit Entire zero (delta zero), reused zero (delta zero) mistake: denying non-accelerated guardant refs/heads/maestro (you ought to propulsion archetypal) To <a class="__cf_email__" data-cfemail="b8dfd1ccf8dfd1cc96ddc0d9d5c8d4dd96dbd7d5" href="/cdn-cgi/l/email-protection">[e mail protected]</a>:myrepo.git ! [distant rejected] maestro -> maestro (non-accelerated guardant) mistake: failed to propulsion any refs to '<a class="__cf_email__" data-cfemail="b1d6d8c5f1d6d8c59fd4c9d0dcc1ddd49fd2dedc" href="/cdn-cgi/l/email-protection">[e mail protected]</a>:myrepo.git'
However bash I acquire the distant repo to return the actual government of the section repo?
If forcing a propulsion doesn’t aid (git propulsion --unit root oregon git propulsion --unit root maestro ought to beryllium adequate), it mightiness average that the distant server is refusing non accelerated-guardant pushes, through both have.denyNonFastForwards config adaptable (seat git config manpage for statement), oregon by way of an replace/pre-have hook.
With older Git you tin activity about that regulation by deleting git propulsion root :maestro (line the : earlier subdivision sanction) and past re-creating git propulsion root maestro fixed subdivision.
If you tin’t alteration this, past the lone resolution would beryllium alternatively of rewriting past to make a perpetrate reverting adjustments successful D-E-F:
A-B-C-D-E-F-[(D-E-F)^-1] maestro A-B-C-D-E-F root/maestro
