`sudo apt upgrade` 期间没有名为“uaclient”的模块（ubuntu 16.04）

我正在尝试将我的桌面从 ubuntu 16.04 升级到 18.04。
（我很后悔没有在 ubuntu 16.04 EOL 到来之前早点升级它。两周前，我将两台 16.04 笔记本电脑升级到了 18.04，尽管那是在 EOL 之后，但当时只有一些小问题我可以解决）。
我这样做了，但之后sudo apt update出现了以下错误。apt upgrade

使用替代系统 (update-alternatives)，命令 python 链接到 python2.7，python3 链接到 python3.5。我接下来该做什么？

添加：
我看到某处说必须重新安装 opca-client，所以我这样做了，

ckim@chan-ubuntu:~$ sudo pip3 install --upgrade opcua-client

然后我看到有关 pip 版本的警告，因此我执行了 sudo pip install --upgrade pip
然后执行了 sudo pip3 install --upgrade opcua-client 但现在看到以下错误：

答案1

对我来说，导致此问题的原因是我在计算机上安装了额外的 Python 发行版/usr/local/bin/python3，该发行版位于搜索路径之前。我手动修改了和中的安装后和/usr/bin/python3删除前脚本，并将其替换为完整路径。这解决了我的问题。/var/lib/dpkg/info/ubuntu-advantage-tools.postinst/var/lib/dpkg/info/ubuntu-advantage-tools.prermpython3/usr/bin/python3

答案2

@Chan Kim，

Reddit 上的一位用户遇到了类似的问题 - 我之前看到了解决方案，即更新 PYTHONPATH 以包含 /usr/lib/python3/dist-packages，然后执行更新。

我在这方面取得了圆满成功。

这是我在系统中使用的。

export PYTHONPATH=${PYTHONPATH}:${HOME}:/usr/bin/python:/usr/lib/python3/dist-packages

答案3

我遇到了类似的问题，这对我有用：

删除 uat，过程将无法完成，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

然后dist-upgrade或do-release-upgrade对我来说很好用。升级到 18.04

答案4

sudo mv /var/lib/dpkg/info /var/lib/dpkg/info_old

sudo mkdir /var/lib/dpkg/info

sudo apt-get 更新

对我有用
