[Tails-dev] [Announcement] Test suite on Stretch|Buster: ple…

Hi,

2 things:

- Running Buster? Please update your APT configuration

- Running Stretch? Please upgrade to Buster or tell me how long you need

Running Buster? Please update your APT configuration
====================================================

So far, in order to run our test suite on Buster, we've required using
a custom backport of QEMU. Good news is that there's now an official
backport in Debian, so please switch to it:

1. ensure you have buster-backports APT sources enabled
2. delete /etc/apt/sources.list.d/isotester-buster.list
3. update /etc/apt/preferences.d/qemu so it has this contents:

Package: qemu*
Pin: release n=buster-backports, o=Debian Backports

4. apt update
5. apt full-upgrade

→ You should have qemu-system-x86 1:5.0-14~bpo10+1 installed.

Running Stretch? Please upgrade to Buster
=========================================

We've now supported running our test suite on Buster since almost
5 months. Now that Stretch is EOL, I would like to stop supporting it,
i.e. start requiring Buster or newer to run our test suite: supporting
Stretch to run our test suite blocks a number of improvements (#17842).

So, if you're still running our test suite on Stretch systems:

- Please consider upgrading to Buster.

If there's anything blocking you, besides available time,
please let me know.

- Does a 3 months delay to upgrade, starting today, sound reasonable
to you? If not, how much more time do you need?

I'll coordinate this upgrade with sysadmins on tails/sysadmin#17731,
since our Jenkins isotesters still run Stretch :)

Cheers!
