请不要关闭重复内容。我已按照另一篇文章中的说明进行操作： 如何安装软件或从旧的不受支持的版本升级？
我也阅读了 Wiki 条目，其中基本上只是说“更新sources.list、更新/dist-upgrade和do-release-upgrade”，就像帖子一样。
https://help.ubuntu.com/community/EOLUpgrades/
它不起作用；我得到以下输出：

不幸的是，我无法复制“......”中的中间部分，因为升级过程启动了一些不允许回滚的子终端进程（我的正常屏幕退出和滚动不起作用，所以谁知道这是什么？）
问题似乎是us.archive.ubuntu.com/ubuntu/实际上没有艺术档案？
下面的一些评论之后添加了澄清：
- 问题似乎是我添加了对 arm64 的多架构支持以支持对 Jetson TX2 的交叉编译（谢谢！）
- 反过来，这不适用于自动镜像选择，因为许多镜像仅镜像英特尔架构（为什么 apt 找不到合适的镜像？）
- 更改所用镜像的建议让我感到困惑，因为我找不到任何关于如何说服
do-release-upgrade使用特定镜像的文档（我确实使用了 Google 20 分钟；我能找到的最接近的答案是如何将它指向我自己的完整存档镜像，但我既不知道如何设置也不想设置） do-release-upgrade专门记录了如何替换系统中现有的 sources.list 文件，这意味着我所做的任何本地编辑都不会应用于版本升级
所以，现在的问题是：我如何说服 do-release-upgrade 使用具有所有适当架构的特定镜像（或中央档案）？
答案1
大多数 Ubuntu 镜像仅支持 x86（i386 arch）和 x86_64（amd64），不包括 arm64 等许多其他架构。因此您有两个选择
- 仅使用主镜
archive.ubuntu.com/.. - 添加限制，在 country.mirror 中仅使用 x86/x86_64
第二种选择的示例是
deb [arch=amd64,i386] http://us.archive.ubuntu.com/ubuntu artful ....
答案2
当我尝试do-release-upgrade在实际arm64机器上运行时也遇到了同样的问题。
最后，我按照这个答案下载（就我而言）artful.tar.gz升级包：
cd somewhere
curl -LO http://archive.ubuntu.com/ubuntu/dists/artful/main/dist-upgrader-all/current/artful.tar.gz
curl -LO http://archive.ubuntu.com/ubuntu/dists/artful/main/dist-upgrader-all/current/artful.tar.gz.gpg
gpg --verify artful.tar.gz.gpg artful.tar.gz
# this will fail, download the key:
gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys 0x...
gpg --verify artful.tar.gz.gpg artful.tar.gz
tar xf artful.tar.gz
然后，从文件中删除所有内容mirrors.cfg，然后仅添加：
http://ports.ubuntu.com/ubuntu-ports/
现在，运行
./artful --mode=server --frontend=DistUpgradeViewText
开始升级过程。
我不知道我怎么会陷入这种情况，这似乎do-release-upgrade不太可能在非 x86/x64 的 Ubuntu 安装上起作用。
