Hi,
I got this notice recently :
====================
There are 11 software packages that can be updated.
python-apt-common (1.6.5ubuntu0.5)
python3-apt (1.6.5ubuntu0.5)
dovecot-managesieved (1:2.2.33.2-1ubuntu4.7)
dovecot-sieve (1:2.2.33.2-1ubuntu4.7)
dovecot-sqlite (1:2.2.33.2-1ubuntu4.7)
dovecot-imapd (1:2.2.33.2-1ubuntu4.7)
dovecot-pop3d (1:2.2.33.2-1ubuntu4.7)
dovecot-lmtpd (1:2.2.33.2-1ubuntu4.7)
dovecot-core (1:2.2.33.2-1ubuntu4.7)
linux-libc-dev (4.15.0-129.132)
cloud-init (20.4-0ubuntu1~18.04.1)
I see dovecot inside, last time some people got some problem with regular postfix update through system package update (ubuntu 18.04)
So its better to wait for a MiaB update ? or is it safe to apply thoses update ?
