Package: acct Version: 6.6.4-5+b2 The acct package installs /etc/cron.monthly/acct which uses the last(1) command.
The `last` command used to be provided by the util-linux package, but it has been deliberately removed starting from util-linux 2.40.1-3 (see util-linux changelog). This means that, with recent versions of util-linux, the cronjob fails with: /etc/cron.monthly/acct: 46: last: not found /etc/cron.monthly/acct: 57: last: not found
