[Qgis-user] Support for 25.04 plucky penguin

[Tony Bazeley]

I've just upgraded from oracular to 25.04 plucky penguin and now find 
3.40.5-Bratislava is installed and I get an error on opening  a project:

"This project file was created by a newer version of QGIS 
(3.42.2-Münster) and could not be completely loaded."

I can't see an entry for plucky in the repository 
<https://ubuntu.qgis.org/ubuntu/dists/?C=M;O=D>

My /etc/apt/sources.list.d/qgis.sources is:Types: deb deb-src URIs: 
https://qgis.org/debian Suites: plucky Architectures: amd64 Components: 
main Signed-By: /etc/apt/keyrings/qgis-archive-keyring.gpg Enabled: yes 
I've updated Suites to "plucky" and I suspect Enabled was updated to no 
on the upgrade.

apt update yiels an error:

Err:11 https://debian.qgis.org/debian plucky Release  404  Not Found 
[IP: 172.67.143.23 443] Error: The repository 'https://qgis.org/debian 
plucky Release' does not have a Release file. Notice: Updating from such 
a repository can't be done securely, and is therefore disabled by default.

Any thoughts on the best way to proceed?

Thanks

Tony
