Como posso resolver isso? Estou em 16.04
Nesta solução, suponho que você tenha instalado o nginx do pacote (não de fontes).
Obtenha uma lista de pacotes instalados como 'nginx': sudo apt list --instalado 2 > / dev / null | grep -i 'nginx'
Revise essa lista e remova os pacotes. Existem vários para 'nginx': nginx, nginx-extras, nginx-completo, nginx-light, etc.
O primeiro comando mostrará o (s) pacote (s) nginx exato (s) que você tem em seu sistema. Do que você pode continuar a removê-lo.
