I run devuan unstable 'ceres' on my Toshiba laptop and my iMac.
It all works with just a bit of weirdness.
I use apt-get update apt-get upgrade and then use aptitude to fix those
upgrades that get held back for various reasons.
Whenever I highlight one of the held back packages and press 'e' to
examine the various possibilities the names of the packages to be
removed or installed are mangled with block characters and/or assorted
characters from other non-Latin1 character sets. Upside down question
marks etc.

Any ideas what is going on?

I am using the slim login manager and then depending on my mood fluxbox,
xfce, or lumina - the new desktop from pc-bsd.
