I'm using PAM module to mount LUKS+dm_crypt encrypted partition during login to avoid additional password prompt. After upgrading from ubuntu 18.4 to ubuntu 20.4 base (mint 19.3 to 20.0) PAM can no longer mount partition (unknown type "crypto_LUKS") while I can mount it manually with cryptsetup luksOpen + mount mapper I just noticed that I no longer have /sbin/mount.crypt utility that looks like was used by PAM. Where it coming from?
It is provided by libpam-mount-bin package that comes with libpam-mount in ubuntu 20.04. All mount.crypt, mount.crypt_LUKS, mount.crypto_LUKS
