我正在更新运行Debian 10的Raspberry Pi。具体来说，我需要从2.9.4（非常旧的！）更新软件包 libxml2 为2.9.14，以保护自己免受 cve-2022-23308 。为此，我不得不将Debian 10（Buster）更新为Debian 11（Bullseye），这使我能够更新许多包装。但是，我只是最新版本的一方面，但是APT使我无法进一步更新？
要尽可能更新，我按以下顺序进行以下操作，遵循这些指令：
- 更新
/etc/apt/sources.list 以及 /etc/Apt/Sources.list.d 中的所有文件以替换所有实例带有“稳定”
-
sudo apt Update
-
sudo apt apt升级
-
sudo apt apo apt apt full-upgrade
-
sudo apto auto autoremove
-
sudo apt clean
-
sudo apt dist -upgrade （现在没有更新）
，当我运行 lsb_release -a 时，我得到：
No LSB modules are available.
Distributor ID: Raspbian
Description: Raspbian GNU/Linux 11 (bullseye)
Release: 11
Codename: bullseye
所以我知道我知道我知道我有最新版本。当我运行 apt列表-All -versions libxml2 时，我得到：
Listing... Done
libxml2/stable,now 2.9.10+dfsg-6.7+deb11u2 armhf [installed]
这都是上下文 - 这是怪异的部分。 sudo apt Update 说所有软件包都是最新的 - 但是我知道这是错误的，因为您可以在Debian的网站上看到更新版本在这里，他们已经出门了一段时间，至少一年了。
实际问题：为什么 apt 假装它具有最新版本，而显然没有？随着Debian更新到最新版本，我应该能够获得其他所有内容的最新版本，对吗？我想念其他作品吗？如何更新此点以获取Libxml2 2.9.14？如果我需要切换到其他发行版或其他重大更改，我会的，但这并不理想：/
非常感谢您的时间和帮助！
I am updating a Raspberry Pi running Debian 10. Specifically, I need to update the package libxml2 from version 2.9.4 (very old!) to 2.9.14, in order to protect myself against CVE-2022-23308. To do this, I had to update Debian 10 (buster) to Debian 11 (bullseye), which allowed me to update a lot of packages several versions ahead. However, I am only partway to the newest version, but apt prevents me from updating further?
To update as far as I have now, I did the following in this order, following these instructions:
- Updated
/etc/apt/sources.list and all files in /etc/apt/sources.list.d to replace all instances of "buster" with "stable"
sudo apt updatesudo apt upgradesudo apt full-upgradesudo apt autoremovesudo apt cleansudo apt dist-upgrade (nothing was updated)
Now, when I run lsb_release -a, I get:
No LSB modules are available.
Distributor ID: Raspbian
Description: Raspbian GNU/Linux 11 (bullseye)
Release: 11
Codename: bullseye
so I know I have the latest version. And when I run apt list --all-versions libxml2, I get:
Listing... Done
libxml2/stable,now 2.9.10+dfsg-6.7+deb11u2 armhf [installed]
That was all context - here's the weird part. sudo apt update says that all packages are up to date - however I know that's false, because you can see newer versions on Debian's website right here, and they've been out for a while, at least a year.
The Actual Question: Why does apt pretend it has the latest version, when it clearly doesn't? With Debian updated to the latest version, I should be able to get the latest version of everything else, right? Am I missing some other piece? How can I update past this point to get libxml2 2.9.14? If I need to switch to a different distro or some other major change, I will, but that's not ideal :/
Thank you so much for your time and help!

我已经尝试了以下操作，它没有帮助解决错误，但我想它确实更新了整个列表：
如果仍然存在问题，请尝试使用“ DNF Update -Nobest”命令。希望这会有所帮助
I have tried the following, it didn't help with the error but I guess it did update the whole list:
If there is still a problem then try with "dnf update --nobest" command. Hope this helps
