嘿，所以我正在研究如何将我的 PPA 从 HTTP 保护到 HTTPS，然后我发现了这篇文章：
由于 Launchpad 确实支持 https，我尝试更新我的源列表：
/etc/apt/sources.list
从 http 到 https：
# deb cdrom:[Kubuntu 21.10 _Impish Indri_ - Release amd64 (20211012)]/ impish main multiverse restricted universe
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.
# deb cdrom:[Kubuntu 22.04 LTS _Jammy Jellyfish_ - Release amd64 (20220419)]/ jammy main multiverse restricted universe
deb https://ubuntu.securedservers.com/ jammy main restricted
## Major bug fix updates produced after the final release of the
## distribution.

答案1
Launchpad 可能会，但是您使用ubuntu.securedservers.com而他们不会。
看看当你打开时会发生什么
https://ubuntu.securedservers.com
当你打开
http://ubuntu.securedservers.com
并且，切换到该域名并不是一个好主意，ubuntu.securedservers.com该域名不属于 Canonical，因此该服务器上发生的任何事情都是不受信任的。
