[SOLVED] 8.3.1 Legacy on Pi Zero - failed upgrade.

[the_bertrum]

This is the cause of the "degraded" status:

Code:

master@prometheus:~ $ systemctl --failed
 UNIT            LOAD   ACTIVE SUB    DESCRIPTION
● haveged.service loaded failed failed Entropy Daemon based on the HAVEGE algorithm

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.
1 loaded units listed

Now to find what that does....
