我正在嘗試從 Ubuntu 18 下的另一台電腦在沒有網路的情況下升級 Ubuntu 16 下的電腦。
$ sudo apt-offline set ~/offline-data.sig
然後我使用 .sig 檔案切換到 Ubuntu18 並嘗試使用 apt-offline 但在嘗試下載軟體包時出現此錯誤：
$ apt-offline get -d ./OfflineUpgrade/ offline-data.sig
Fetching APT Data
Traceback (most recent call last):

我的離線資料.sig 如下所示：

我該如何解決這個問題？
答案1
所以，問題來自於 apt-offline 對 .sig 檔案的不同寫入。在我編寫的 Ubuntu 16 中，該檔案以幾行空白文字結尾：
'http://fr.archive.ubuntu.com/ubuntu/dists/xenial-backports/multiverse/dep11/icons-64x64.tar.xz' fr.archive.ubuntu.com_ubuntu_dists_xenial-backports_multiverse_dep11_icons-64x64.tar 0
Enable UA Infra: ESM to receive additional future security updates.
See https://ubuntu.com/esm or run: sudo ua status
而讀取它的 Ubuntu 18 則以整行結束：
'http://at.archive.ubuntu.com/ubuntu/pool/main/i/initramfs-tools/initramfs-tools-bin_0.130ubuntu3.12_amd64.deb' initramfs-tools-bin_0.130ubuntu3.12_amd64.deb 11156 MD5Sum:43c52cbf0447849d6997b454b4fc8d8d
所以刪除最後幾行就可以了。
