在“`sudo升级”期间没有名为“uaclient”的模块(ubuntu 16.04)
我正在尝试将我的桌面从ubuntu16.04升级到18.04。(我感到遗憾的是，在before 16.04 EOL到达之前，我没有对其进行升级。两周前，我已经将两本16.04笔记本升级到18.04，尽管它是在EOL之后，但当时我只能解决一些小问题)。我做了sudo apt update，但是在此之后的apt upgrade过程中，我得到了下面的错误。

@Chan-Kim，
Reddit上的一个用户也有类似的问题--我之前看到了这个解决方案，它是更新PYTHONPATH以包含/usr/lib/python3 3/dist-包，然后执行更新。
我在这方面取得了完全的成功。
这就是我在我的系统里使用的。
export PYTHONPATH=${PYTHONPATH}:${HOME}:/usr/bin/python:/usr/lib/python3/dist-packagesAsk Ubuntu用户

对我来说，造成这个问题的原因是我在我的计算机/usr/local/bin/python3上安装了额外的python发行版，它位于搜索路径中的/usr/bin/python3之前。我手动修改了/var/lib/dpkg/info/ubuntu-advantage-tools.postinst和/var/lib/dpkg/info/ubuntu-advantage-tools.prerm中的安装后和预删除脚本，并用完整的路径/usr/bin/python3替换了python3。这解决了我的问题。

我也遇到了类似的问题，这对我来说很有效：
删除uat，进程将不完成，可能缺少uaclient.apt。
sudo apt-get remove ubuntu-advantage-tools然后通过以下方式手动删除uat：
sudo mv /var/lib/dpkg/info/ubuntu-advantage-tools.* /tmp/
sudo dpkg --force-remove-reinstreq --purge ubuntu-advantage-tools
sudo dpkg --remove --force-remove-reinstreq ubuntu-advantage-tools那么dist-upgrade或do-release-upgrade对我来说很好。升级至18.04
