Android系统源码AOSP repo sync报错:info: A new version of repo is available

小编在ubuntu-18.04.4 Android系统源码R(Android 11)下载及编译同步代码的时候，一直报错，下面是解决办法
info: A new version of repo is available
warning: repo is not tracking a remote branch, so it will not receive updates
repo reset: error: Entry 'SUBMITTING_PATCHES.md' not uptodate. Cannot merge.
fatal: Could not reset index file to revision 'v2.18^0'.

报此问题是因为 repo也是需要升级的，从aosp-latest.jar中解压后，repo sync同步时，有可能远程仓库(android源码仓库)已经更新了，报的问题也是远

Android系统源码AOSP repo sync报错:info: A new version of repo is available最先出现在Python成神之路。
