今天早上，我像往常一样使用适用于 Windows 10 的 GUI 更新了 TeX Live，但我收到了一些我从未见过的消息。
这是 GUI 中显示的日志。
第一次尝试：

如此处所示：“跳过强制删除的软件包 xxx”是什么意思？我应该关心它吗？，我也尝试过：
- 检查重新安装以前删除的软件包勾选后按更新所有已安装的按钮
- 跑步
tlmgr update --all --reinstall-forcibly-removed：
命令提示符上显示的内容如下：

发生了什么？
答案1
可能正如 Ulrike 所说，tlmgr update --all --reinstall-forcibly-removed问题解决了。
今天texlive-docindex已正确更新：
