无法打开文件 archive.ubuntu.com_ubuntu_dists_eoan-updates_restricted_cnf_Commands-amd64.xz

来自孟加拉国的问候。我是 Ubuntu 操作系统的中级用户。我在 apt 更新方面遇到了问题。我在网上搜索过，但找不到任何答案，所以我发了这个问题，请帮帮我。

我曾尝试过

  1. 完全删除部分文件夹的内容。
  2. 清洁sudo apt clean moving the lists to lists.old then updating the apt

但运气不佳。

答案1

我已从列表中删除了受限的软件源，并通过以下方式进行了更新，sudo apt update然后再次将受限的软件源添加到列表中，并再次进行了另一次更新，错误就消失了。
