do-release-upgrade 在 WSL 中从 18.04 LTS 升级到 20.04 LTS 静默失败

Question

是时候将 Ubuntu 从 18.04 升级到 20.04 了！但在进程没有错误消息的情况下中止之前我并没有走得太远。是否有日志文件可供我查看以获取更多信息？

显然，有/var/log/dist-upgrade/main.log. 它所显示的只是Quirks.focalPostInitialUpdate“叫abort”。

其他文件/var/log/dist-upgrade也没有透露任何信息。

附加信息：

• Windows 已提前更新（以防出现某些 WSL 问题）。
• sudo apt update && sudo apt upgrade没有帮助。

我遇到过同样的问题。据我所知，我以为我没有安装 snap，也没有 PPA。检查了一下/var/log/dist-upgrade/main.log，没有任何错误。这是输出：

事实证明，我已经安装了 snapd，并将其删除解决了问题。
