Downloading Android Source Tree Error

While setting up my Android Dev Environment on Ubuntu 10.04 LTS, I ran into some errors. No matter how many times I reran repo sync, repo sync -f, etc. the errors would continue to show up. I believe it was due to some corruption during download. Either way, the two folders I had trouble with were Gallery.git and Exchange.git.

The Errors:
computer@ubuntu:~/WORKING_DIRECTORY$ repo sync
Fetching projects:  75% (166/221)  fatal: Not a git repository: '/home/computer/WORKING_DIRECTORY/.repo/projects/packages/apps/Gallery.git'
Fetching projects:  76% (168/221)  error: unable to resolve reference refs/remotes/aosp/ics-factoryrom-2-release: No such file or directory
From https://android.googlesource.com/platform/packages/apps/Exchange
 ! [new branch]      ics-factoryrom-2-release -> aosp/ics-factoryrom-2-release  (unable to update local ref)
...

error: Cannot fetch platform/packages/apps/Gallery
error: Cannot fetch platform/packages/apps/Exchange

error: Exited sync due to fetch errors


Solution/Fix

I went to WORKING_DIRECTORY/.repo/projects/packages/apps/Gallery.git
and Exchange.git and deleted them.

Then I reran repo sync, and the dev environment completed successfully.
