Debian 9: /var/lib/apt/periodic/update-success-stamp not found

[clecherbauer]

I tried to run apt_exporter on Debian 9 and got this exception:

Jan 19 21:05:45 apt_exporter[15566]: time="2020-01-19T21:05:45+01:00" level=fatal msg="no such file or directory" source="apt_exporter.go:359"

I think this is the cause:

apt_exporter/apt_exporter.go

Line 244 in 4aecd1e

if err := e.watcher.Add("/var/lib/apt/periodic/update-success-stamp"); err != nil {

Directly after a new installation of Debian the /var/lib/apt/periodic directory is empty.
Maybe these files are firstly written after the execution of the APT Periodic cron. Furthermore the file /var/lib/apt/periodic/update-success-stamp is named /var/lib/apt/periodic/udate-stamp.

For which distribution did you develop this exporter?

Hi! Thanks for checking this out, that's nice to see! I've built this exporter for Ubuntu and never tried it on Debian (let alone a fresh installation), so I'm not surprised to see it failing.

Given that it gets this far, I assume this means /var/log/apt/history.log does exist on Debian? Do you know if it creates /var/lib/apt/periodic/update-success-stamp at some point, or if it has a similar file. I added these watchers with out-of-band updating to avoid having the apt calls during the HTTP endpoint, as they are rather slow.

@lebokus Would you mind trying again with the version I just pushed (v0.3.0). I believe both issues should have been addressed (the file not existing, and the different name of the stamp file on Debian).

Sorry for not responding - I will test it tonight.

Thank you very much!

@pmaene Yeah this fixed it. Thanks for your effort :)

Great, happy to hear that! Thank you for checking!
