Bash not found

Help
#1

Hello everybody

I have been trying to install LibreNMS on a Raspberry Pi 3 for a long time. Unfortunately I can’t do it :frowning_face:

Therefore I have completely rebuilt the Raspberry.
Basis: Raspberry Pi OS (32-bit) based on Debian Buster

I have now regained control from the beginning and fail in the “install PHP dependencies” section.

I use the instructions here: https://docs.librenms.org/Installation/Install-LibreNMS/
-> Debian 10 selected

I am logged in as root and the following error appears:

[email protected]:~ $ sudo -s
[email protected]:/home/pi# cd /opt
[email protected]:/opt# su - librenms
su: failed to execute /usr/bin/bash: File or directory not found
roo[email protected]:/opt# ./scripts/composer_wrapper.php install --no-dev
bash: ./scripts/composer_wrapper.php File or directory not found

What can I do here to solve the problem and proceed with the installation?

Thanks for the help and best regards!

The question has been resolved. I installed Nagios.
Worked without problems and is now up and running.

Thanks anyway :wink:

@MTR You didn’t have bash installed, which is a requirement, but not explicitly in the install docs because normal installs have bash.

Hello @murrant

Thank you very much for your feedback.

Bash was not even present in the Required Packages.

What is the easiest way to install Bash now?

#5

apt install bash

#6

bash is already installed

bash is already the latest version (5.0-4).
0 updated, 0 newly installed, 0 to be removed and 0 not updated.

#7

Is there anything else I can do to install bash and thus LibreNMS?

Thanks a lot for your help!

#8

I would google about that error and how to fix it, as that is out of librenms scope.

Maybe bash is only in /bin/ and you should change it in the passwd file?

Hello and thanks for your reply @TheGreatDoc

And how can I change that in the passwd file?

#10

nano /etc/passwd
change the line at the end of your username to point to /bin/bash
john:x:1000:1000:john,:/home/john:/bin/bash
