我需要将drbd8升级到drbd9。为此，我遵循本文档。
https://www.linbit.com/drbd-user-guide/drbd-guide-9_0-en/#s-升级drbd
步骤1
root@oreo:~# add-apt-repository ppa:linbit/linbit-drbd9-stack
This PPA contains DRBD9, drbd-utils, LINSTOR (client, python API, server).
This differs from official, production grade LINBIT repositories in several ways, including:
- We push RCs immediately to the PPA
- We don't push hotfixes, these usually have to wait until the next RC/release
- We only keep 2 LTS versions up to date (Bionic and Focal, but not Xenial)
For support and access to official repositories see:
https://www.linbit.com or write an email to: sales AT linbit.com
More info: https://launchpad.net/~linbit/+archive/ubuntu/linbit-drbd9-stack
Press [ENTER] to continue or ctrl-c to cancel adding it
gpg: keybox '/tmp/tmp68jovxd3/pubring.gpg' created
gpg: keyserver receive failed: No keyserver available
步骤2接下来，您需要将DRBD签名密钥添加到您的可信密钥中
wget -O- http://packages.linbit.com/gpg-pubkey-53B3B037-282B6E23.asc | apt-key add -
步骤3最后执行一次apt更新，以便Debian识别更新后的存储库。
apt update
我得到错误像这个
apt-get update

请帮我
ppa应该只在Ubuntu及其衍生产品上运行。
在debian上要安装drbd9，您需要：
将gpg密钥添加到您的密钥环：
gpg --keyserver keyserver.ubuntu.com --recv-keys 0x53B3B037282B6E23
gpg --export -a 0x53B3B037282B6E23 |sudo apt-key add -
在/etc/apt/sources.list:中添加以下行
deb http://packages.linbit.com/<hash>/ stretch drbd-9.0
其中<hash>:是您通过电子邮件收到的40个字符的访问哈希。
然后运行：
sudo apt update
sudo apt install drbd9-utils
E: Failed to fetch http://ppa.launchpad.net/linbit/linbit-drbd9-stack/ubuntu/dists/hirsute/main/binary-amd64/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.
这是404，因为该路径不存在。参观http://ppa.launchpad.net/linbit/linbit-drbd9-stack/ubuntu/dists/查看所有可用的发行版。
LINBIT通常只为LTS版本提供软件包。虽然，我相信，Hirsute将是一个未来的LTS版本。它目前仍在开发/未来发布中。
