Issue ERROR: Apt cache fetch failed.

[Pascal_Netenvie]

Looking at log i see i had a problem with an outdated siging key for sury.org repo.
So i executed this command :

apt-key adv --fetch-keys https://packages.sury.org/php/apt.gpg

I will see tomorrow morning if it solve the problem.

If you want to update keys and update + upgrade in one command :

apt-key adv --fetch-keys https://packages.sury.org/php/apt.gpg && apt update && apt -y upgrade

It's seems ok now, but i'm not sure it's because sury signing key update.
There was a plesk update to 18.0.59u2, perhaps they fixed something ...

I gave you bad information
the error message this morning was only on one of my VPS
but it wasn't the same error as usual

Raison : 2024-03-06 06:27:05 INFO: pum is called with arguments: ['--list', '--repo-info', '--json']
2024-03-06 06:27:05 ERROR: Failed to lock directory /var/lib/apt/lists/: E:Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
2024-03-06 06:27:05 ERROR: Exited with returncode 1.

so I guess the update also solved my first problem

Please check whether the case described in Issue - run-parts: /etc/cron.daily/pleskupdate exited with return code 1 applies to you.

Hello and thank you for your interest in my problem.

I read your post
but I'm not at Strato
and I have nowhere "pleskupdate" in my files
I did a search with the command: "find / -iname "pleskupdate"
and I found nothing
I went to see "/opt/psa/admin/sbin/pleskupdate" and "/etc/cron.daily/pleskupdate"
and I have nothing

I happen to have the same error every other day on several servers.

I checked "/var/log/plesk/install/autoinstaller3.log", but could not see any errors.

Running "apt update" works fine.

Issue - run-parts: /etc/cron.daily/pleskupdate exited with return code 1 does not apply to me, as these servers are root servers, with ordinary
plesk versions installed. There are no customization / relations to Strato or others.

Affected are:

Server1:
Ubuntu 22.04.5 LTS
Product version: Plesk Obsidian 18.0.75.0
OS version: Ubuntu 22.04 x86_64
Build date: 2026/01/02 11:00
Revision: 801e61a105f5d0cc9331ee8f33e76e4c2f4121e9

Server2:
Ubuntu 20.04.6 LTS
Product version: Plesk Obsidian 18.0.75.0
OS version: Ubuntu 20.04 x86_64
Build date: 2026/01/02 11:00
Revision: 801e61a105f5d0cc9331ee8f33e76e4c2f4121e9

Do you get the same result when you run apt-get update? If not, what I can suggest as a workaround is to to disable the system updates notification with the following command:

plesk bin notification --update -code admin_pum_updates -send2email false

What else I can suggest is to changing the time Plesk's daily maintenance task runs. I know that helped users experiencing a similar issue.

On a side note, I would like to add that the case was reviewed by our team (recently as well) and it was not recognized as a Plesk issue - it is suspected to a system related issue.

Thank you for your answer.

It seems, that it depends on the hour the tasks are run. I haven't seen this issue again. And if, I will
follow, what is recommended here: https://support.plesk.com/hc/en-us/...Daily-Maintenance-tasks-run-on-a-Linux-server
