我正在尝试使用以下命令安装一些图形库：
sudo apt install jpegoptim optipng
但是它无法运行，并显示以下内容：
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following NEW packages will be installed:
jpegoptim optipng
0 upgraded, 2 newly installed, 0 to remove and 273 not upgraded.
Need to get 0 B/208 kB of archives.
After this operation, 625 kB of additional disk space will be used.
dpkg: warning: 'find' not found in PATH or not executable
dpkg: error: 1 expected program not found in PATH or not executable
Note: root's PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin
E: Sub-process /usr/bin/dpkg returned an error code (2)
然后我尝试find使用以下命令进行安装：
sudo apt-get install findutils
但它安装失败，因为它说它已经安装：
Reading package lists... Done
Building dependency tree
Reading state information... Done
findutils is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 273 not upgraded.
我注意到我的/etc/environment文件是空的，我添加了以下内容：
PATH=/sbin:/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin
不幸的是，这也没有奏效。它仍然导致：
Reading package lists... Done
Building dependency tree
Reading state information... Done

我还尝试将以下内容放入.bashrc文件中：
export PATH=$PATH:/sbin:/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin
但它仍然抱怨 PATH 不正确。
答案1
sudo apt-get --reinstall install findutils
“重新安装”选项允许您重新安装已安装的最新版本的软件包。
即使这有效，我也会担心你的 /usr/bin/find 之前已经消失了，如果它没有被错误删除，那么你的系统可能被黑客入侵了？
