So is the only way to install is to compile the code myself, or is there another install method? I am finding that dot most times completes (with the leak messages), but sometimes it just fails. Thanks for at least cluing me in to the situation with .deb installs.
Is there a particular feature from 11.0.0 you need? Despite the massive version number jump, there’s actually not a lot of difference between 2.42.2 (available natively in Ubuntu 22.04) and 11.0.0 for command line use.
If you want to build from source, the ubuntu-22.04 directory in the repository’s ci directory will tell you what dependencies to install and then download the 11.0.0 tarball from the download page, untar that, ./configure --prefix=/somewhere/to/install && make && make install.
