Hi all,

Same issue here... but for Imunify360.

2025-06-02 06:25:27 INFO: pum is called with arguments: ['--list', '--repo-info', '--json']

And when I try to check for package updates in Plesk I get 'Error: Unable to receive update information for the package(s)'.

Total newbie here but wondering if the apt update list cache needs to be cleared? Don't want to try it until someone who knows what they are doing advises!

Thanks!
 
Same issue here after updating to 18.0.69 and 18.0.70 now - Plesk Obsidian v18.0.70_build1800250523.14 os_Ubuntu 24.04
 
Regarding the PHP 7.4 and PHP 8.0 warnings, the workaround we can suggest is:

echo 'APT::Key::Assert-Pubkey-Algo ">=rsa2048,ed25519,ed448,dsa1024";' | sudo tee /etc/apt/apt.conf.d/99weakkey-warning

However, please do proceed with caution as the action can impact the overall security of the system. Our team is already working on releasing a fix. I will follow up with more details.
 
i am also getting error when i am trying to access my project panel of plesk its saying that

the link is this https://host.adremindia.com:8443/

This page isn’t working right now​

host.adremindia.com can't currently handle this request.


HTTP ERROR 500

anyone else on a STRATO VPS Linux V server which recently has been moved to new hardware?
I think the error started to occur after VM was moved to new hardware
 
Everyone, the issues with PHP 7.4 and PHP 8.0 and the signing keys should be sorted. Our team released an update:

The GPG signing keys for the PHP 7.4 and 8.0 repositories on Ubuntu 24.04 have been updated addressing apt-get failure “untrusted public key algorithm: dsa1024”. (PPPM-14985)

Please let us know if you continue encountering any errors/warnings.

Hello, @yohanr . From what I can see the error you are getting is related to CloudLinux's repository. They are aware of the issue and a fix should be introduced soon. You may apply the workaround mentioned previously:
