We use mod_php in our installations, those php-fpm instructions are too complicated and unnecessary in this case.

What instructions did you follow to update the OS? What OS is it?

Ubuntu is generally quite simple, you just do do-release-upgrade and it upgrades. Sometimes a few things break, but they're usually obvious to fix, often you can just copy/paste our package install lines from the install guide to add any missing packages on the new OS.

Note that if you used CentOS/RHEL or similar, you're probably better off burning the server and starting again.

Andy, it sounds like you do not have apache configured correctly to handle php.  You might look at this…but ignore the “mod_php” part, you want to use php-fpm

Advice please ! 😊

I have a server which has been running Observium well for some time.

Although upgrading the Observium build is easy enough following the instructions at Updating - Observium https://docs.observium.org/updating/#upgrading-the-subscription-edition-to-the-very-latest-version this obviously does not update the O/S itself.

I had a try at upgrading following online instructions yesterday but after he upgrade was complete the Observium web interface would not display – I just got a page of text which I assumed to be PHP script being displayed rather than “running”.

Does anyone have any idiot proof (ie aimed at Linux novice) guidance to upgrade the OS without breaking Observium ?

Luckily I had taken a snapshot of the VM so could roll back without any drama.

Thanks,

Andy Hartwell

Some release upgrades can be a pain when they change some packaging demarcation resulting in missing packages or change daemons resulting in basic things not working (2010 era ubuntu would disable logins on update :D)

Take a dump of the database, copy of rrd directory and config.php and update it all the way to the current, then figure out what's broke. If it's forever broke you can install latest Ubuntu LTS and restore the database and RRDs.

Generally we recommend Ubuntu because they're a little bit less likely to screw over their users to prove how much they love the GPL.

If you can't make it work give me a shout and I can probably fix it.

The initial issue you had would probably be fixed by copy/pasting our package install lines from install guide, then our lines to make sure PHP is enabled further down the guide. Sometimes when switching between PHP versions, deb won't actually activate the new packages, presumably because they package *name* itself is versioned, if you know what I mean.

Adam,

Server is currently running Debian 10 (Buster) – I was attempting to take it up to 11 (Bullseye) and if that worked I’d try my luck going up again to 12 (Bookworm).

I followed these instructions : https://phoenixnap.com/kb/upgrade-debian-10-to-11

I panicked and restored the VM back as soon as I saw it “broke” observium (or more likely PHP) rather than spend anytime trying to workout how I could repair it as I would have little or no clue where to start looking.

I figured that if I asked here I’d at least get some pointers.

Thanks.
