Resolved /opt/psa/libexec/modules/watchdog missing - crontab errors

[mit]

Hi Plesk-Friends,

First, merry Christmas to everyone.

I used the time to upgrade my VPS from ubuntu 18.04 (with latest Plesk version) to ubuntu 22.04.1 (with latest Plesk version). I decided to take a backup of my old VPS, re-install the VPS, and restore the backup. Everything went smooth (with some minor situations I managed to solve).

However, now I am getting crontab errors for different files in /opt/psa/libexec/modules/watchdog/cp/

Like:
/bin/sh: 1: /opt/psa/libexec/modules/watchdog/cp/clean-events: not found
/bin/sh: 1: /opt/psa/libexec/modules/watchdog/cp/pack-sysstats: not found
/bin/sh: 1: /opt/psa/libexec/modules/watchdog/cp/pack-sysstats: not found

(and some more)

I checked the path, and only /opt/psa/libexec/modules/ is available (but empty).
Crontab however shows a list with jobs on that cp folder:

:/opt/psa/libexec/modules# crontab -l

MAILTO="<Removed>"

My question, is /opt/psa/libexec/modules/watchdog/cp/ with the files supposed to exist (and missing files is the issue), or the cronjobs are orphan (and I should delete those)?

I tried to uninstall the watchdog module, but no luck:
/usr/local/psa/admin/bin/autoinstaller --select-product-id plesk --select-release-current --remove-component watchdog
/usr/local/psa/admin/bin/autoinstaller --select-product-id plesk --select-release-current --install-component watchdog

Any idea?

Thanks,
MIT

Hi,

The watchdog component is not supported in Unbuntu 22.04:

Hey Maarten,
Great, thank you. I see... In this case, I will simply disable those cron jobs.

Thanks again,
Mat

Great, thank you. I see... In this case, I will simply disable those cron jobs.

I'd also recommend to run
# /usr/local/psa/admin/bin/autoinstaller --select-product-id plesk --select-release-current --remove-component watchdog
again. I am not sure why the software allowed the installation in the first place as Watchdog is not supported on that OS.
