手动安装包时出错

我正在尝试使用 TeX Live 在我的 Linux 机器上手动安装我大学提供的 Latex 格式。我的 TEXMFLOCAL 文件夹是/usr/local/share/texmf。我将所需的文件复制到此处的子目录中。但是，我无法mktexlsr在此处运行。

以下是我尝试过的：

mycomp:/usr/local/share/texmf # whoami
root
mycomp:/usr/local/share/texmf # mktexlsr
mktexlsr: Updating /etc/texmf/ls-R... 
/usr/lib/mktex/mktexlsr: line 184: /usr/local/share/texmf/ls-R: Permission denied

mktexlsr: Done.

mycomp:/usr/local/share/texmf # touch ls-R
mycomp:/usr/local/share/texmf # ls -l

drwxr-xr-x 3 root root 4096 Apr 20 16:36 tex

mycomp:/usr/local/share/texmf # mktexlsr

我在这里做错了什么？

编辑：

的输出ls -ld为：

mycomp:/usr/local/share/texmf # ls -ld
drwxrwxr-x 4 root root 4096 Apr 25 17:33 .

问题是你的/usr/local/share/texmf属于 组root，而它应该来自mktex。

这文档提到setgid，但这里没有设置：

ls -l /usr/bin/mktexlsr
lrwxrwxrwx 1 root root 21 Nov 19  2014 /usr/bin/mktexlsr -> /usr/lib/mktex/public

ls -l /usr/lib/mktex/public
-rwxr-xr-x 1 root mktex 11032 Oct 15  2014 /usr/lib/mktex/public

我们希望有人能找到解释。

同时，下面介绍如何解决这个问题：

cd /usr/local/share/texmf/
# create ls-R if it does not exist yet
sudo touch ls-R
# change the ls-R group to mktex
sudo chgrp mktex ls-R
# change file mode bits (readable by all, writable by root and mktex group)
sudo chmod 664 ls-R

查看：

ls -l /usr/local/share/texmf/ls-R 
-rw-rw-r-- 1 root mktex 246 Mar 13 11:39 /usr/local/share/texmf/ls-R
