I am doing right now a fresh installation of Matomo v4.1.0
and I got the information that I should delete vendor/bin/lessc
In my opinion a fresh installation should not contain any not needed files
Thanks for creating this issue @mathContao
We've already prepared a fix for this in https://github.com/matomo-org/matomo-package/pull/124 and will close this issue as a duplicate see https://github.com/matomo-org/matomo/issues/16938
This should be fixed in one of the next 1-2 releases.
