On recent EC2 bookworm AMIs (as observed with our mr13.2.1 EC2 build
with AMI ID ami-09ca7561204a0d1d4), the bookworm-backports repository is
enabled by default:
| admin@ip-10-0-0-204:~$ cat /etc/apt/sources.list.d/debian.sources
| Types: deb deb-src
| URIs: mirror+file:///etc/apt/mirrors/debian.list
| Suites: bookworm bookworm-updates bookworm-backports
| Components: main
| Signed-By: /usr/share/keyrings/debian-archive-keyring.gpg
|
| Types: deb deb-src
| URIs: mirror+file:///etc/apt/mirrors/debian-security.list
| Suites: bookworm-security
| Components: main
| Signed-By: /usr/share/keyrings/debian-archive-keyring.gpg
Our own valkey-server + valkey-tools backport has the identical *version*
number with a *higher* apt pinning though:
| admin@ip-10-0-0-204:~$ apt-cache policy valkey-server valkey-tools
| valkey-server:
| Installed: 8.0.1+dfsg1-1~bpo12+1

This causes installer to fail therefor with:
| Making sure all packages are up to date ...
| Reading package lists...
| Building dependency tree...
| Reading state information...
| Calculating upgrade...
| The following packages will be DOWNGRADED:
| valkey-server valkey-tools
| 0 upgraded, 0 newly installed, 2 downgraded, 0 to remove and 0 not upgraded.
| E: Packages were downgraded and -y was used without --allow-downgrades.
| ABORTED: Error upgrading packages
We need to make sure that such a backports repository isn't enabled by
default.
