問題可能來自您的 /etc/resolv.conf 文件，檢查您是否有一些
nameserver指令並嘗試 ping archive.ubuntu.com這是我的 resolv.conf ：
domain local search local nameserver 8.8.8.8 nameserver 8.8.4.4我使用Google的公共 dns ( https://developers.google.com/speed/public-dns/ )
然後嘗試 apt-get update
它檢測到它獲得的一些文件已過時或損壞，因此它們無法使用。刪除記憶體文件，
rm -rf /var/lib/apt/lists/*然後重試apt-get update.如果問題仍然存在，則某處的記憶體代理可能仍在保存舊的或損壞的內容。
apt-get update -o Acquire::http::No-Cache=True在這種情況下可能會有所幫助。
