Hi Rohit and community,
I am ok with deprecating ubuntu 16.04 support in CloudStack 4.15.
Me as well. We have until April 2021 before 16.04 goes EOL and I don't
think it's worth the effort.
It is very important to document the upgrade path from ubuntu
16.04/python2/old cloudstack versions to ubuntu 20.04/python3/cloudstack
4.15. We probably need to modify cloudstack 4.14 to support ubuntu 20.04 as
a bridge, if we do not stop vms.
1. ubuntu 16.04/python2/old cloudstack versions , upgrade to
2. ubuntu 16.04/python2/cloudstack 4.14, then upgrade to
3. ubuntu 20.04/python2/cloudstack 4.14 (and live migrate vms), then
upgrade to
4. ubuntu 20.04/python3/cloudstack 4.15
any other workaround ?
Not that I can see quickly. But yes, a point release of 4.14 probably
needs to support 20.04 so people can easily upgrade.

Kind regards,
Wei

All,
Ubuntu 16.04 does not have JRE11 package as well as some packages for
Python3 such as python3-distutils:
https://packages.ubuntu.com/search?suite=default§ion=all&arch=any&keywords=python3-distutils&searchon=names
The Java 11 JRE requirement was introduced starting the 4.14.0.0 release
and in the release notes workaround for JRE installation was mentioned [0].
With master/4.15 support for Python3 was added for KVM hosts and the
management server but a critical issue [1] was recently identified due to
which cloudstack-agent would fail installation on the older Ubuntu 16.04
due to missing python3-distutil (and other) dependencies.
Ubuntu 16.04 will reach the end of standard support by April 2021 [2][3],
and the next 4.15 release will add support for Ubuntu 20.04 [4][5] - so
should we:
(a) remove Ubuntu 16.04 from our list of supported distribution (for KVM
host and management server) in 4.15?
(b) (if there are users using 16.04) document workaround for
installation/upgrade in the 4.15 release/upgrade notes?
Thoughts, feedback? Thanks.
