Por que o status do dkms "AVISO! Diferença entre módulo construído e instalado" acontece?

mas a saída de dkms statuspermanece a mesma.

Por que isso acontece? Devo me preocupar? E se eu deveria me preocupar, como eu faria para consertar isso?

drivers kernel 18.04 dkms

    Você pode ver a resposta em sua saída.

    dkmsdescobriu que a versão do módulo (não a versão do pacote dkms) é a mesma que está agora no kernel em execução e não a substitui.

    Mas o código é diferente e é mostrado na dkms statussaída.

    Você pode corrigi-lo incrementando a versão do módulo no código-fonte ou usando --forcea opção sugerida.

    Uma resposta curta é: isso acontece porque nada está realmente instalado.

    Parece que você precisava deste pacote DKMS com um kernel 5.0 mais antigo. Agora o Ubuntu 18.04 está usando o kernel 5.3 que possui esse módulo nativamente. Então você pode remover os dkms agora.
