Composer problem

hello,
I have a problem with my Librenms running on Ubuntu 15.10.

When a run validate.php I have this :
[FAIL] No composer available, please install composer
[FIX] https://getcomposer.org/

I have installed composer but with no luck !

Thanks for your help.
regards.

I had the same problem.

I followed this advice:

After apt removing the package running ./validate.php again installed it for me, no more error.

Thanks !
The composer message have been gone after removing composer package.

I have now new problems with validate.php :
root@SRV:/opt/librenms# ./validate.php

@mourillostak you need to fix all that follow the commands its telling you.

@mourillostak Unrelated - but definitely not helping your cause - your server is beyond end of support - an upgrade to an LTS build (16.04) would be a positive move too.
