Topic on Talk:Gerrit/Advanced usage

I am working on a patch that depends on another that's still under review.

1. Patch A: parent patch still under review.
2. Patch B: depends on A.

I have made new patchsets for A and on patch B's page, Gerrit shows that the dependency(patch A) is [OUTDATED].

Steps I have followed to fix this issue:

1. Checked out patch A (git review -d 'patchA')
2. Checked out existing patch B (git review -d 'patchB')
3. git rebase review/user/patchA
4. makes changes to a file
5. git add 'files'
6. git rebase --continue shows 'No rebase in progress?'
7. git commit --amend
8. git push gerrit HEAD:refs/for/master

git push throws error ' ! [remote rejected] HEAD -> refs/for/master (squash commits first)'.

How can I fix this?
