Works here.
The `forummain` feature only goes back to 2020-03-12, so unless you're running a pre-release build of Fossil from the current trunk, that name won't work. In prior versions, only `/forum` worked. (I guess drh just didn't like `/forum/forum` and wanted the second level to be distinct from the first.)
As for `forumnew`, that should always work, going back to very early in the Forum feature's lifetime, which was initially released as part of Fossil 2.7.
Therefore, I would guess that this and your prior problem come from using an older version of Fossil, such as 2.5, which Ubuntu was still shipping, last time I checked.

The default view shows check-ins only. Either pull down the right-most pull-down in the submenu bar and select Forum or give this command:
$ fossil timeline -R forum
