使用`sudo apt install sendmail`安装  
结果如下：

sudo dpkg --configure -a
    Setting up sendmail-bin (8.15.2-3) ...
    Updating sendmail environment ...
    Reading configuration from /etc/mail/sendmail.conf.
    Validating configuration.
    Writing configuration to /etc/mail/sendmail.conf.
    Writing /etc/cron.d/sendmail.
    Disabling HOST statistics file(/var/lib/sendmail/host_status).
    Reading configuration from /etc/mail/sendmail.conf.
    Validating configuration.
    Writing configuration to /etc/mail/sendmail.conf.
    Writing /etc/cron.d/sendmail.
    Could not open /etc/mail/databases(No such file or directory), creating it.
    Reading configuration from /etc/mail/sendmail.conf.
    Validating configuration.
    Creating /etc/mail/databases...
    
    Checking filesystem, this may take some time - it will not hang!
      ...   Done.
    
    Checking for installed MDAs...
    sasl2-bin not installed, not configuring sendmail support.
    
    To enable sendmail SASL2 support at a later date, invoke "/usr/share/sendmail/update_auth"
    
    
    Creating/Updating SSL(for TLS) information
    Creating /etc/mail/tls/starttls.m4...
    Creating SSL certificates for sendmail.

卡在最后这一行，还有个进度条停在80%不动了。  
解决方案：

cd /etc/mail/tls
    sudo openssl dsaparam -out sendmail-common.prm 2048
    sudo chown root:smmsp sendmail-common.prm
    sudo chmod 0640 sendmail-common.prm
    sudo dpkg --configure -a
