I am trying to install some graphics libraries with the following command:

sudo apt install jpegoptim optipng

It however fails to run with stating the following:

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)

I then try to install find with the following command:

sudo apt-get install findutils

But it fails to install as it says it is already installed:

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.

I noticed that my /etc/environment file was empty and I added the following to that:

PATH=/sbin:/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin

Unfortunately that has not worked either. It stil results in:

Reading package lists... Done
Building dependency tree 
Reading state information... Done

I have also tried putting the following in the .bashrc file:

export PATH=$PATH:/sbin:/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin

but it still complains about the PATH being incorrect.

The servers I am working with were setup around 2 years ago. I have been working with them for around a week and this is the first time I am attempting to install something.

Could anyone help out here with any other solutions that I am missing?

Thanks
