Just a generalized question for all the folks who use any Raspberry Pi for ADSB flight tracking.
How often should the Pi be updated ?
sudo apt update
sudo apt dist-upgrade
Thanks,
Glenn
Only when there is a new version of Piaware, otherwise I leave it alone.

I look after a whole bunch of Pis and when I first install stuff on them, I ensure they’re fully, completely up to date. When I look at the uptimes, I can see that some of them have been up for many hundreds of days.
I’ve only recently rebuilt my two feeders and they’d both been up for nearly a year. That’s how long since I last updated the OS.

Well you can update everything but the kernel without rebooting 
Of course there is no urgent need to.

I was under the impression that regular updates are useful (maybe essential) for security issues.
The PiAware runs on a Debian Linux system and all Linux systems have regular security updates - as does Windows and Mac.
Must admit I don’t update my two PiAware systems as regularly as my main Linux laptop but I do run the update commands however tend to go for sudo apt update rather than dist-upgrade.

I hope you mean upgrade?
Always need “apt update” to update the package lists and then “apt upgrade” (no matter which variety) to actually upgrade the installed software.

Yep, did indeed mean upgrade

It wasn’t broke - I upgraded - it’s broken. A bit…
No updated graphs for “Disk I/O” since I upgraded the RPi kernel today from Linux version 4.14.98-v7+ to Linux version 4.19.42-v7+ (package raspberrypi-kernel 1.20190517-1).
This kernel has some changes in /proc/diskstats that Collectd v5.7.1 can’t handle.
Reference on GitHub: /proc/diskstats changes in Linux 4.19 #2951
You’re all warned! And @wiedehopf will probably get some questions on his graphs I guess…
Yeah i hit that problem quite some time ago and there has been some discussion in the graphs thread.
I’ve listed it as a known bug on my github page as well.
Thought about making a workaround but decided against it.
We’ll just have to wait until the fix that is already in collectd makes it into a Raspbian package.
That could be some time but to be honest the disk graphs aren’t that important in my opinion.
I installed package collectd-core_5.8.1-1.3_armhf.deb from Index of /raspbian/pool/main/c/collectd over version 5.7.1-1.1 and it works again.
Only the RRD-file disk-mmcblk0/pending_operations.rrd is not being updated anymore.

Wasn’t being used anyway in the graphs.
Downloading the package seems to be a nice alternative.
wget -O /tmp/collectd.deb http://raspbian.raspberrypi.org/raspbian/pool/main/c/collectd/collectd-core_5.8.1-1.3_armhf.deb
sudo dpkg -i /tmp/collectd.deb
This works nicely but when they change version the download will stop working.
Anyway i’ll mention it in the graphs thread.
