Unable to Cherry Pick (FETCH), but able to Pull & Push in Gerrit Git

Question

As I said in the title, I am able to push to the gerrit, pull from the gerrit, but I am not able to cherry pick. When I asked the admin, he said I have all the rights to cherry pick, but I get the error as:

Error Message

Permission denied (publickey).
fatal: The remote end hung up unexpectedly

When I try to Pull and Rebase

Summary

My application runs on Ubuntu 12.04 on a VirtualBox instance. All my peers are able to cherry-pick, and I find the issue is only with my machine, and that too with cherry-pick by FETCH. What might be the issue? What do you guys suggest? What information other than this, do you need?

Update #1

Git Config

praveen@praveen-vbox:~/work/myapp$ git config --list
alias.s=status
alias.c=commit
alias.ca=commit --amend
alias.co=checkout
alias.dc=diff --color
alias.l=log --oneline
alias.pr=pull --rebase
alias.aa=add .
user.email=[removed] /* Removed before posting to SO. Email matches. */
core.editor=vim
color.ui=always
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
core.repositoryformatversion=0
core.filemode=true
core.bare=false
core.logallrefupdates=true
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
remote.origin.url=gerrit:myapp.git
branch.master.remote=origin
branch.master.merge=refs/heads/master

For Titas's query, the result is:

praveen@praveen-vbox:~/work/myapp$ git fetch gerrit refs/changes/96/5396/3
fatal: 'gerrit' does not appear to be a git repository
fatal: The remote end hung up unexpectedly

Also, when I do normally, this is the result:

praveen@praveen-vbox:~/work/myapp$ git fetch ssh://praveen@my.appdomain.com:29418/myapp refs/changes/96/5396/3 && git cherry-pick FETCH_HEAD
Permission denied (publickey).
fatal: The remote end hung up unexpectedly

Update #2: SSH Config

As requested by RasmusØstergaardKjærVoss, I have included below the SSH Config file. Let me know if there's something to be changed.

praveen@praveen-vbox:~/work/myapp$ cat ~/.ssh/config
Host gerrit
HostName my.appdomain.com
Port 29418
User praveen
IdentityFile ~/.ssh/praveen_private

Answer 1

This gave me the same error:

ssh firstname.lastname@my.appdomain.com

changing to:

ssh firstname.lastname@gerrit.appdomain.co

fixed the problem for me.

Answer 2

The ~/.ssh/, to my understanding git fetch ssh://praveen@my.appdomain.com:29418/ will use the id_rsa key and not the ~/.ssh/praveen_private.

Backup your ~/.ssh folder Then try and create a copy of ~/.ssh/praveen_private named ~/.ssh/id_rsa If it is an rsa key otherwise copy it to ~/.ssh/id_dsa

Cheers

Answer 3

Something is wrong with your settings in git or gerrit, or in the overall settings for your gerrit deployment. You can run a git pull, which basically runs git fetch && git merge under the covers. But you can't run the git fetch command you copy-paste from gerrit. Look at the output of git remote -v and compare it to the git fetch portion of the cherry-pick command you are trying to run. Are you hitting the exact same server URL & port? As the same user?

Lastly, as a connection test to Gerrit, try running something like ssh username@gerrit_host -p 29418 gerrit ls-projects. This should return a list of projects on the Gerrit server, and is a good way to work out any setting issues.
