Servidor degradado, como resolver isso

Question

Sou novo no Ubuntu e começo a entender os princípios.

Meu servidor mostra após systemctl status o estado do servidor degradado.

Eu encontrei o comando systemclt --failed e ele me mostrou o seguinte:

UNIT                         LOAD   ACTIVE SUB    DESCRIPTION
● plesk-php54-fpm.service      loaded failed failed The PHP 5.4.45 FastCGI >Proce
● plesk-php55-fpm.service      loaded failed failed The PHP 5.5.38 FastCGI >Proce
● plesk-php70-fpm.service      loaded failed failed The PHP 7.0.21 FastCGI >Proce
plesk-php71-fpm.service      loaded failed failed The PHP 7.1.7 FastCGI Proces

● systemd-tmpfiles-setup-dev.service loaded failed failed Create Static Device >N

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

6 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

Agora as versões php que ele está tentando carregar não são usadas por mim. Mas os comandos para systemctl não tenho certeza se eles influenciam o desempenho.

Se alguém tiver uma sugestão, eu serei grato.

Eu tentei usar a função de pesquisa e o google, mas não encontrei algo adequado. Mas também é possível que eu não soubesse o que ajuda.
