Problema installazione pacchetti su server debian

[fermat]

ciao!

su un server non mio, e che non gestisco io, devo installare un pacchetto, ma mi da errore:

# aptitude install php-mysql
The following NEW packages will be installed:
  php-mysql php8.2-mysql{a} 
0 packages upgraded, 2 newly installed, 0 to remove and 23 not upgraded.
Need to get 124 kB of archives. After unpacking 480 kB will be used.

E: Unable to fetch some packages; try '-o APT::Get::Fix-Missing=true' to continue with missing packages

avete qualche idea su come risolvere??

penso che il problema sia una chiave scaduta:

ho provato a fare il renew senza successo:

# apt-key adv --keyserver keys.gnupg.net --recv-keys B188E2B695BD4743
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
