Salva ed esci. Quindi aggiorna il tuo repository:

sudo apt update

Quindi installare php-mbstring:

sudo apt install php7.2-mbstring

Le informazioni del pacchetto che sono a aptconoscenza non sono aggiornate.

Usando lo rmadisonstrumento, possiamo vedere tutte le versioni dei php7.2-mbstringrepository:

 php7.2-mbstring | 7.2.3-1ubuntu1         | bionic/universe          | amd64, arm64, armhf, i386, ppc64el, s390x
 php7.2-mbstring | 7.2.7-0ubuntu0.18.04.2 | bionic-security/universe | amd64, arm64, armhf, i386, ppc64el, s390x
 php7.2-mbstring | 7.2.7-0ubuntu0.18.04.2 | bionic-updates/universe  | amd64, arm64, armhf, i386, ppc64el, s390x

anche se sto solo mostrando gli oggetti Bionic qui.

Poiché il tuo sistema non è a conoscenza del più recente php7.2-mbstringnei repository di sicurezza o aggiornamenti, stai riscontrando una mancata corrispondenza della versione.

Esegui questo:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install php7.2-mbstring

Ciò dovrebbe aiutare a riportare le versioni dove devono essere. (Nota che potresti voler usare dist-upgradeinvece upgradeche in modo che pacchetti come pacchetti kernel aggiornati vengano installati e aggiornati anche)
