Hi -

I am not able to get my 'repo upload' to work for Android. I followed
an earlier mail thread on the similar issue
http://groups.google.com/group/repo-discuss/browse_thread/thread/c8e68f9b4dfb143b/c868fb37d4b5a434?lnk=gst&q=repo+upload#c868fb37d4b5a434

Following is the details of my Android Open Source account:
Username: Vikas
Full Name: Vikas Arora
Email Address: vik...@google.com
Account ID: 1006707

Just to make sure I have not missed nay step, I did following:
- Registered my SSH keys
- cd ~/.ssh; ssh-keygen -t rsa -C vik...@google.com; cat id_rsa.pub;
- Added my public SSH keys generated in first step to 'https://
review.source.android.com/#settings,ssh-keys'

- Initializing a Repo client
- repo init -u git://android.git.kernel.org/platform/manifest.git
- In the above step, provided my Full Name & Email Address
(vik...@google.com) as specified in my AOSP account.
- repo sync -j 16

- Verifying Git Tags (Load the following public key into your GnuPG
key database)
- gpg --import
- Copy pasted following pub-key (ref: http://source.android.com/source/downloading.html)
-----BEGIN PGP PUBLIC KEY BLOCK-----
Version: GnuPG v1.4.2.2 (GNU/Linux)

I got following response:

- git tag -v TAG_NAME
I got an error: "error: tag 'TAG_NAME' not found."
// Not sure if I need to worry about this error or this is just
some redundant error

- Build & code changes
- Edited some files in git project 'external/webp', commit the
changes 'git commit -a'
- make -j 16

- Upload code for review:

Is your username on the local machine the same as your email username?

If it isn't you can set it in your ssh configuration (~/.ssh/config):
Host <host>
User <username>

or you can do it via repo:
git config --global review."<URL>".username <username>

Best way to find out would be to ssh <host> -p 29418 gerrit,
if that doesn't work try adding -l vikasa and try again...

Sorry you're having so much trouble. Clearly we need to improve our
documentation in that area.

IIRC that can come from two areas:

-username mismatch
-key issue

On the username front, you need to check in Gerrit settings that you
do have an ssh username set up. It's the first field at
https://review.source.android.com/#settings

Also, the default behavior is to assume that your ssh username is the
username in the email address you set up during repo init. If that's
not the case, Ian gave details later in the thread about how to manage
the mismatch. I've recently helped someone do it successfully with git
config --global
review.https://android-git.corp.google.com/g/Gerrit.username
<username>

On the key side, things can be harder to diagnose. Luckily, it's easy
to eyeball that your public key has been properly uploaded. Once
that's the case, the rest tends to boil down to invoking ssh-add
and/or ssh-agent in the right order with the right parameters... and
as far as I'm concerned that's black magic.

Ian -

Ok so I tried following and still getting the same issue :-(

- I changed the .ssh/config to make sure I have correct username:

vikas[101] cat .ssh/config

Host github.com

User git

Hostname github.com

IdentityFile /home/vikasa/.ssh/id_rsa

Host review.source.android.com

User vikasa

IdentityFile /home/vikasa/.ssh/id_rsa

- Tried setting username with 'git config'

git config --global review.https://android.git.kernel.org.username vikasa

- My username (LDAP) is 'vikasa' and my email registered is 'vik...@google.com'

- I tried ssh to review.source.android.com

vikas[108] ssh review.source.android.com -p 29418 gerrit -l vikasa

Permission denied (publickey).
