What is the problem here and does it affect anything? Thanks!

Simply remove php5-snmp package. You can use this command in a console to do so:

sudo apt-get remove php5-snmp

With PHP 7, the package is php7.0-snmp:

sudo apt-get remove php7.0-snmp

For those of us that need the php5-snmp package, the above may not solve your problem. In that case you can try:

sudo apt-get install snmp

which will install snmp for you, which seems to be required for the php5-snmp package to avoid outputting those errors.

apt-get install snmp-mibs-downloader

Isn't this the best answer? Found @ https://serverfault.com/questions/440285/why-does-snmp-fail-to-use-its-own-mibs

If you're using php 5. Simply remove php5-snmp package

sudo apt-get remove php5-snmp

If you're using php 7. Remove php7.0-snmp package.

sudo apt-get remove php7.0-snmp

This also helped me. sudo apt-get install snmp

https://www.digitalocean.com/community/questions/installed-php-7-0-now-returns-errors

You should try a reinstall through apt-get

sudo apt-get remove php
sudo apt-get install php

In most cases it is enough to just reinstall the offending extension.

sudo apt-get remove php5-snmp

Try to update packages:

sudo apt-get update
sudo apt-get upgrade
/etc/init.d/apache2 restart

and if it not help, try to reinstall php

sudo apt-get remove --purge php5
sudo apt-get install php5
/etc/init.d/apache2 restart

this error display in cacti poller error logs when snmp-mibs-downloader not installed

vim /etc/apt/sources.list

add to sources "non-free" packages

apt-get update apt-get install snmp-mibs-downloader /etc/init.d/apache2 restart

These warning messages appear because the PHP init can not find the mod config in the user dir. So you have to do the following steps:

1. edit your etc/php/{yourversion}/mods-available/snmp.ini and comment or delete the following strings:

   ; configuration for php snmp module ; priority=20 ;extension=snmp.so ~
   ~

2. run apt-get --purge remove php-snmpt

I spent a few hours on this and wanted to share how I solved it in case someone searches for this error and still needs to use php-snmp module (removing that module also removes the error). /etc/snmp/snmp.conf has a setting: mibs ALL

This tells the net-snmp library to attempt to load every mib file. If you do not need this you can comment that out and the errors are gone. If you still want to load every mib file continue reading.

In ubuntu 16.04 setting the environment MIBDIR to /usr/share/mibs stopped these errors for me. I needed this to happen on every session for php CLI runs so I created /etc/profile.d/mibs.sh with: export MIBDIRS=/usr/share/mibs

No more php errors from CLI.

To disable the error for cronjobs I added the same ENV in the cron file where the errors were happening.

If someone knows why not setting MIBDIRS causes these errors, I would love to hear. I can only assume the default for this in net-snmp are not compatible with ubuntu 16.04 mibs downloader.
