我曾经使用过该multicolumn软件包。如今，该软件包显然已无法通过 CTAN 和 获得tlmgr。为什么multicolumn它不再可用？我看到的最接近的匹配软件包是多色我想知道这是否是下一代和/或替代为了multicolumn。
为了便于理解，我回顾了一个 2020 年的项目，该项目tlmgr install multicolumn可能有效，并且这样的代码片段很有用……尽管我在标题部分没有看到任何\usepackage内容：multicolumn

我今天遇到的错误看起来像这样，这让我认为multicolumn很可能在某一时刻存在：
tlmgr install: package multicolumn not present in repository.
tlmgr: action install returned an error; continuing.
tlmgr: package repository https://ctan.math.illinois.edu/systems/texlive/tlnet (not verified: valid signature with expired key)
tlmgr: An error has occurred. See above messages. Exiting.
答案1
好的。可以肯定的是，它multicolumn不存在，并且我一直在查看某种无效的 Dockerfile。我tlmgr info | grep multicol在之前有用的容器/镜像中运行它，但没有发现任何multicolumn存在的迹象。
