Hi,
We are going to setup autopkgtest env for riscv64. But got errors from the cmd:
```

The autopkgtest-build-lxc will invoke the lxc-create:
` lxc-create -B best --name=autopkgtest-sid-riscv64 -t debian -- -r sid -a riscv64`. It will get the same error also.
We can ignore the btrfs related error because executing `sudo autopkgtest-build-lxc debian sid` on amd64 gets the same hint（and the rootfs-sid-amd64 is setup well）
So, I think the issue cause is due to the ports release file is not compatible with lxc-build as the error described.

In fact, Using debootstrap cmd to setup debian riscv64 base chroot will get the error sometime but we can pass --no-check-gpg arg to debootstrap. But the autopkgtest does not support it maybe.

Any help will be appricated.

Inspired by Debian ci folks on IRC, I hacked the /usr/share/lxc/templates/lxc-debian script as follow(for debian-ports, there is should patches to fix the issue) :

```

debootstrap --verbose --variant=minbase --arch="$arch" --no-check-gpg --include=debian-ports-archive-keyring \
--include=$packages \
"$release" "$cache/partial-$release-$arch" "$MIRROR"

```

The downloading of the minmium Debian rootfs is ok. But got another error at last(I am not sure this will or not affect autopkgtest):
```

I am a bit worry about the unmatched board that does not support function as above described.
