Answer 3

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

Answer 4

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.

Answer 5

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.

Answer 6

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
