尝试从 Ubuntu 20.04 LTS 升级到 Ubuntu 22.04 LTS

Question

我正在尝试将我的系统从 Ubuntu 20.04 LTS 升级到 Ubuntu 22.04 LTS。我做到了

% sudo apt upgrade
% sudo apt autoremove
% sudo do-release-upgrade

它顺利地犁了几分钟，然后发生了这种情况：

Installing the upgrade can take several hours. Once the download has 
finished, the process cannot be canceled.

解决办法是手动删除麻烦的包并尝试重新进行升级。我对此进行了多次迭代，甚至对一个难以卸载的软件包使用了“aptitude”。尽管如此，仅用了几个小时的努力就克服了困难。比全新安装容易得多。
