Merge accidental hg heads?

Question

Please help me merge the heads that I didn't want in the first place:

    C:\Users\hg\>hg push
    pushing to https://usernm@bitbucket.org/zzz/yyy
    http authorization required
    realm: Bitbucket.org HTTP
    user: 
    password:
    searching for changes
    abort: push creates new remote head 841acfa3a36b!
    (merge or see "hg help push" for details about pushing new heads)

    C:\Users\hg\m>hg merge
    abort: uncommitted changes
    (use 'hg status' to list changes)

    C:\Users\hg\>

C:\Users\hg>hg commit -m " merge"
nothing changed (12 missing files, see 'hg status')

outstanding uncommitted changes in repository C:/Users/hg/, not merging with pulled head

Answer 1

abort: uncommitted changes

Tells you in clean English: you must commit before merge

Answer 2

Try this:

hg push -f -r Number_Rev
