如何将升级失败修正反向移植到 trusty？

由于启动板中的 Bug#1611470，Ubuntu 14.04.5->16.04 升级失败。

我启动do-release-upgrade它失败，因为错误#1611470。该错误已修复，但修复后的版本升级程序在 trusty 中不可用。如何将更正向后移植到 trusty？

2016年更新。10月15日：应用Stephen推荐的补丁后出现同样的错误。这是引用：

Traceback (most recent call last): File "/tmp/ubuntu-release-upgrader-4_bu5g66/xenial", line 8, in <module> File "/tmp/ubuntu-release-upgrader-4_bu5g66/DistUpgrade/DistUpgradeMain.py", line 242, in main File "/tmp/ubuntu-release-upgrader-4_bu5g66/DistUpgrade/DistUpgradeController.py", line 1876, in run File "/tmp/ubuntu-release-upgrader-4_bu5g66/DistUpgrade/DistUpgradeController.py", line 1841, in fullUpgrade File "/tmp/ubuntu-release-upgrader-4_bu5g66/DistUpgrade/DistUpgradeController.py", line 1257, in doDistUpgrade UnboundLocalError: local variable 'e' referenced before assignment Error in atexit._run_exitfuncs: Traceback (most recent call last): File "/tmp/ubuntu-release-upgrader-4_bu5g66/DistUpgrade/DistUpgradeController.py", line 1062, in _enableAptCronJob PermissionError: [Errno 1] Operation not permitted: '/etc/cron.daily/apt'

以下应该有效...

  1. 下载DistUpgradeController.diff某处（例如，~/Downloads）

  2. 从同一目录，尝试将补丁应用到受影响文件的副本：

    cp /usr/lib/python3/dist-packages/DistUpgrade/DistUpgradeController.py .
patch -p1 < DistUpgradeController.diff

  3. 如果这不会产生任何错误，请将修复的文件复制到位（首先进行备份）：

    sudo cp /usr/lib/python3/dist-packages/DistUpgrade/DistUpgradeController.py{,.bak}
sudo cp DistUpgradeController.py /usr/lib/python3/dist-packages/DistUpgrade/

如果这一切都成功，您将应用修复程序#1611470。
