http://wiki.cyanogenmod.com/wiki/HTC_Desire_(GSM):_Compile_CyanogenMod_(Linux)出現(xiàn)如下問題：
1.repo init時報錯：
......
object 30d452905f166b316152f236422f85c8aa75a2d0
type commit
tag v1.7.5

gpg: Can't check signature: public key not found
error: could not verify the tag 'v1.7.5'
出錯原因是曾使用repo sync從其它庫sync過代碼，刪掉~/.repoconfig即可：
$ rm -rf ~/.repoconfig
$ ./repo init -u git://github.com/CyanogenMod/android.git -b gingerbread
gpg: keyring `/home/calvin/.repoconfig/gnupg/secring.gpg' created
gpg: keyring `/home/calvin/.repoconfig/gnupg/pubring.gpg' created
gpg: /home/calvin/.repoconfig/gnupg/trustdb.gpg: trustdb created
gpg: key 920F5C65: public key "Repo Maintainer <repo@android.kernel.org>" imported
gpg: Total number processed: 1
gpg:?????????????? imported: 1

連接服務器時的問題，解決：
修改.repo/manifest.xml中
? <remote? name="korg"
?????????? fetch="git://android.git.kernel.org/"
?????????? review="review.source.android.com" />
為
? <remote? name="korg"
?????????? fetch="http://android.git.kernel.org/"
?????????? review="review.source.android.com" />
