do-release-upgrade中python的unicodedecodeerror解决办法
更新：最后发现错误的是我没安装过的包，最后还是屏蔽了Tsinghua的源解决了，这就很尴尬了
建议先尝试一下删除第三方源
错误出现在17.10升级到18.04的过程中，错误代码是

根据上文提示可定位到出错点在/tmp/ubuntu-release-upgrader-dsz1my1q/DistUpgrade/DistUpgradeCache.py的825行
打开对应文件找到相应行，在其上必经处添加
|
1 |
logging.debug("%s \n" % pkg) |
使其输出错误的pkg
以我为例，我定位的825行出错点位于函数installedTasks(
|
1 |
for pkg in self: |
后面添加了
|
1 |
logging.debug("%s \n" % pkg) |
随后，运行该升级包，最后执行的bionic要根据要升级的版本变化
|
1 |
/tmp/ubuntu-release-upgrader-dsz1my1q/bionic |
依然报错，但现在我们就可以去日志文件查看刚刚添加命令的输出内容。
在我的问题中，日志文件位于/var/log/
