After I update one of our Debian 10 hosts:
# apt-get update -y && apt-get upgrade -y --auto-remove
I re-run updates list and always see this package:
# apt list --upgradable
Listing... Done
linux-image-amd64/oldstable 4.19+105+deb10u17 amd64 [upgradable from: 4.19+105+deb10u15]
N: There is 1 additional version. Please use the '-a' switch to see it
Why does upgrade not update it? Should it be upgraded? How?
