Cannot run Calibre

Hello.

I have managed to successfully install Calibre on my 32-bit Kali Linux using the commands as provided on the Calibre site:

sudo -v && wget -nv -O-https://raw.githubusercontent.com/kovidgoyal/calibre/master/setup/linux-installer.py | sudo python -c "import sys; main=lambda:sys.stderr.write('Download failed\n'); exec(sys.stdin.read()); main()"

When I try to run the commands 'calibre' and 'calibre-debug', I get the output:

bash: calibre: command not found

It gives me the same thing when I try to run 'calibre-debug'. When I navigate to the /opt/calibre directory where the program was installed, the commands still do not work. It is only when I run them as './calibre' and './calibre-debug' that I get any response.

When I run './calibre' from within the /opt/calibre directory, I get the following output:
Traceback (most recent call last):
File "site.py", line 53, in main
File "site.py", line 14, in set_default_encoding
File "locale.py", line 511, in getdefaultlocale
File "locale.py", line 443, in _parse_localename
ValueError: unknown locale: en_ZM

And when I run './calibre-debug', I get the following output:
Traceback (most recent call last):
File "site.py", line 53, in main
File "site.py", line 14, in set_default_encoding
File "locale.py", line 511, in getdefaultlocale
File "locale.py", line 443, in _parse_localename
ValueError: unknown locale: en_ZM

If anyone can help point me in the right direction so that I get my Calibre working, I would be very grateful. I have Googled ad-infinitum, and none of the solutions seem to be clear enough to follow. :blink:

I'm an intermediate user of Linux and I am willing to edit whatever files, configure, compile etc. so that the program runs successfully as well as provide relevant information to aid in the troubleshooting. :book2:

Thanks in advance.
