I just downloaded the .deb file: cherrytree/now 0.38.11-0 all [installed,local]
Previously I was running 0.38.10.
After installing 0.38.11, it wanted to download a newer version, after that the installer said that this version was already installed, but said it was 0.38.9.
For some reason, it now correctly says it is 0.38.11!?!?!?
So problem solved, but how…
