我有 Python 2.7.15+ 符号链接到python
和 Python 3.6.7 符号链接到python3
。当我尝试使用以下方法将 Ubuntu 升级到 19.04 时
sudo do-release-upgrade
它返回以下错误:
Traceback (most recent call last):
File "/tmp/ubuntu-release-upgrader-k7w2kx7r/disco", line 8, in <module>

在升级 Ubuntu 之前,我尝试升级所有 Python 软件包:
pip freeze --local | grep -v '^-e' | cut -d = -f 1 | xargs -n1 pip install -U
这就是它失败的原因吗?
答案1
这似乎通常源于 pip 安装的 distro-info 版本掩盖了 apt 版本 [...]
如果您在这里寻找快速解决方案:
sudo python3 -m pip uninstall distro-info sudo apt reinstall python3-distro-info

我自己解答了这个问题。
我找到了有问题的python脚本:
/usr/local/lib/python3.6/dist-packages/distro_info.py
然后覆盖它:
https://salsa.debian.org/debian/distro-info/raw/master/python/distro_info.py
然后运行sudo do-release-upgrade,成功。
