I run byobu on my home server, and I noticed this today - what is it?

It's part of the byobu notification/status bar, on a 64-bit 11.10 server.

From man pages:

updates_available - the number of updates available on the system; displayed in the lower bar toward the right in white text on a red background with a trailing '!' sign; if any updates are marked 'security updates', then there will be a total of two trailing exclamation points, '!!'

  • Is there any way to tell what these updates are? I am using byobu on a mac (installed with brew) and all brew packages are up to date. It's driving me bonkers ... the 1! since I can't tell what it is!!!

    @AhiTuna check for apt-check: python3 /usr/lib/update-notifier/apt-check --human-readable. Dec 11, 2018 at 2:26

This shows the number of packages that need to be updated on the system.
