我想在我的 Debian/Windows 双启动笔记本电脑上安装 TuxOnIce，因为我无法正常pm-hibernate工作。关注一些教程，我做了以下几件事：
添加了 TuxOnIce ppa: sudo apt-add-repository ppa:tuxonice/ppa。它似乎有效，但在确认输入后我收到以下错误：
gpg: keybox '/tmp/tmp2dbcfl9z/pubring.gpg' created
gpg: /tmp/tmp2dbcfl9z/trustdb.gpg: trustdb created
gpg: key DAC45EC9DEC8FAAC: public key "Launchpad PPA for TuxOnIce" imported
gpg: Total number processed: 1
gpg: imported: 1
gpg: no valid OpenPGP data found.

现在更新sudo apt-get update会显示比以前更长的项目列表。大多数都以 this 开头，http://ppa.launchpad.net/tuxonice/ppa/ubuntu bionic/main这很奇怪，因为我没有 Ubuntu，而且我读到 Ubuntu 软件包与 Debian 并不真正兼容。有些链接会出现 404 错误，但大多数链接都有效。同样，输出以一些错误结束：
Reading package lists... Done
W: The repository 'http://ppa.launchpad.net/tuxonice/ppa/ubuntu bionic Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://ppa.launchpad.net/tuxonice/ppa/ubuntu/dists/bionic/main/binary-i386/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.
使用 来安装应用程序sudo apt-get install tuxonice-userui linux-generic-tuxonice linux-headers-generic-tuxonice。该软件包tuxonice-userui已安装，但找不到其他软件包：
E: Unable to locate package linux-generic-tuxonice
