These are provided by the "apt" package, which you should not remove as
it is required for the normal maintenance of a Debian system. Attempting
to remove it will result in the following dire warning:
WARNING: The following essential packages will be removed.
This should NOT be done unless you know exactly what you are doing!
0 upgraded, 0 newly installed, 24 to remove and 0 not upgraded.
After this operation, 261 MB disk space will be freed.
You are about to do something potentially harmful.

I like to do all my package management manually, so I use "systemctl
mask" to prevent these units from starting.
I use three levels of systemd prevention:
- "systemctl stop": stop a running unit.
- "systemctl disable": prevents a unit from being started by default,
but does not prevent a unit from being started by another unit or by
some socket witchcraft.
- "systemctl mask": prevents a unit from being started. Ever. The AK47
of unit prevention. When you absolutely positively have to stop a unit
from starting. (Apologies to Samuel L Jackson in "Jackie Brown".)
I think I used something like:
systemctl mask apt-daily-upgrade.timer
systemctl mask apt-daily.service
systemctl mask apt-daily.timer
Now "ls -al /etc/systemd/system" contains these:
lrwxrwxrwx 1 root root 9 May 5 2017 apt-daily-upgrade.timer ->
lrwxrwxrwx 1 root root 9 Apr 15 2017 apt-daily.service -> /dev/null
lrwxrwxrwx 1 root root 9 Apr 15 2017 apt-daily.timer -> /dev/null
