我将系统从 ubuntu-20.0.4 升级到 ubuntu-22.04.1，在运行以下命令时出现一个警告：
sudo apt update
警告是
W: Skipping acquire of configured file 'somerville-cory-tgl/binary-i386/Packages' as repository 'http://dell.archive.canonical.com jammy InRelease' doesn't have the component 'somerville-cory-tgl' (component misspelt in sources.list?)

我检查了我的源列表，它根本不包含“somerville-cory-tgl”。我的 source.list 文件如下

（编辑）但是，我确实在目录中somerville-cory-tgl名为的不同文件中找到了文本oem-somerville-cory-tgl-meta.list/etc/apt/sources.list.d/
文本看起来像
deb http://dell.archive.canonical.com/ jammy somerville
# deb-src http://dell.archive.canonical.com/ focal somerville
deb http://dell.archive.canonical.com/ jammy somerville-cory-tgl
# deb-src http://dell.archive.canonical.com/ focal somerville-cory-tgl
如果我注释掉deb http://dell.archive.canonical.com/ jammy somerville-cory-tgl这一行，那么问题就解决了，但我不确定这一行有多重要，因为我可以看到其中的内容http://dell.archive.canonical.com/dists/jammy/somerville/。它可能很重要。
我该怎么做才能解决这个问题？
答案1
让我们退一步来看看为什么会有 OEM 档案。您需要知道这一点才能理解答案。
包括戴尔在内的一些 OEM 厂商会将他们的设备送到台湾的 Canonical 团队进行硬件测试，并寻求新硬件 Linux 兼容性方面的帮助。（这也是Ubuntu 认证硬件）
该兼容软件需要一两年的时间才能进入 Linux 内核，但在此期间，Ubuntu 用户需要 OEM repo 才能使他们的新硬件正常运行。当通用 Linux 内核包含该兼容性时，不再需要 OEM repo。
现在来回答一下：
两年前，您的硬件需要该 OEM 存储库。但现在情况已不再如此，通用 Linux 内核应该可以在您的硬件上正常工作，并且该特定存储库已停产。
这就是您收到警告的原因：Apt 告诉您 repo 已停止。（Apt 不知道原因）
只需禁用（注释掉）该somerville-cory-tgl行即可。
由于您没有收到有关该somerville线路的警告，因此请保持其处于活动状态。
答案2
从上面大家就可以知道原因了。
我在戴尔机器上遇到了这个问题。
为了禁用 somerville-*，你可以
cd /etc/apt/sources.list.d
sudo rm oem-*
