Issue Ubuntu upgrade from 22.04 to 24.04 getting issue with key algorithms

[Daveo]

Server operating system version

Ubuntu 24.04

Plesk version and microupdate number

18.0.68

I upgraded a friend's server from Ubuntu 22.04 LTS to 24.04 LTS using the instructions from here, and now apt update is saying key algorithms are weak.

Seems Ubuntu 24.04 requires key algorithms to be at least RSA2048 minimum.

Looking at list it produces. It saying Plesk & Imunify keys don't meet the minimum algorithm level.

How do I fix this ?

@Daveo These issues have been present for a long time now.
Read all of this thread (but just all of the weak key algorithms part(s) as the Roundcube part was finally fixed):
Issue - Plesk Updates - Expected in 18.0.65 - Now Overdue
In theory, they will be fixed by Plesk, soon-ish

OK, thanks for that
