If you don't have graphical access like Winbox or Webfig to a MikroTik router you can easily do software updates via the command line. These commands can be used in Ansible playlists as well to programatically update devices.

A few package channels exist and you can select which branch you'd like. The current branch is always recommended because it's the latest stable release:

/system package update set channel=current

If you prefer to live on the bleeding edge or if you want to test new features in development use the Release Candidate channel:

/system package update set channel=release-candidate

With the channel selected run the update check:

/system package update check-for-updates

If a new version is available download it:

/system package update download

New package files being detected will trigger the install when the device boots.

Kick off the installation by rebooting the router:

/system reboot
