ucsf-chimerax-daily 的安装后脚本返回 Python 错误

这个问题是在我安装了一个准备不充分的 ucsf-chimerax 安装文件后出现的，导致了以下错误：

dpkg: error processing package ucsf-chimerax-daily (--configure):

ucsf-chimerax-daily

该程序运行良好，我在菜单中没有遇到任何问题。只有消息令人厌烦。每次我安装新软件或升级软件包时，错误都会再次出现。

答案1

这是 UCSF ChimeraX 发行版中的一个错误。请将 UCSF ChimeraX 的错误报告给[电子邮件保护]以便为所有用户修复这些问题。幸运的是，我们发现了这个问题，因此已经修复。请尝试下一个每日发布版本（2018-10-17）。

答案2

我编辑了该文件/var/lib/dpkg/info/ucsf-chimerax-daily.postinst，注释掉了执行其他操作然后回显消息的命令。

然后我就跑了

sudo apt upgrade

有些消息例如

W: APT had planned for dpkg to do more than it reported back (0 vs 4).
   Affected packages: ucsf-chimerax-daily:amd64

但问题解决了。我认为

sudo dpkg --configure ucsf-chimerax-daily:amd64

也能完成这项工作。
