“sudo apt-key add-”无效

tag-icon • tag-icon command-line 20.04 add-apt-repository
“sudo apt-key add-”无效

此命令：

sudo add-apt-repository ppa:upubuntu-com/network -y

返回：

Cannot add PPA: ''This PPA does not support focal''.

然后，我将跳过对“add-apt-repository”基本部分的回答和过度回答，直接进入正题。

此命令：

sudo gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv A5D712AEE06E6293
sudo gpg -a --export A5D712AEE06E6293 | sudo apt-key add -
sudo bash -c "echo -e 'deb http://ppa.launchpad.net/upubuntu-com/network/ubuntu wily main\ndeb-src http://ppa.launchpad.net/upubuntu-com/network/ubuntu wily main' > /etc/apt/sources.list.d/upubuntu-com-ubuntu-network-wily.list"

返回正确的输出但是当我去运行时：

sudo apt-get update

同样返回错误：

W: GPG error: http://ppa.launchpad.net/upubuntu-com/network/ubuntu wily Release: The following signatures were invalid: DED04C8CBB517AE45B073F12A5D712AEE06E6293
E: The repository 'http://ppa.launchpad.net/upubuntu-com/network/ubuntu wily Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

存储库：

deb [ trusted=yes allow-insecure=yes allow-weak=yes allow-downgrade-to-insecure=yes check-valid-until=no ] http://ppa.launchpad.net/upubuntu-com/network/ubuntu wily main
deb-src [ trusted=yes allow-insecure=yes allow-weak=yes allow-downgrade-to-insecure=yes check-valid-until=no ] http://ppa.launchpad.net/upubuntu-com/network/ubuntu wily main

使用以下命令：

sudo apt-get update --allow-unauthenticated --allow-insecure-repositories

没有效果，但错误信息变短了：

W: GPG error: http://ppa.launchpad.net/upubuntu-com/network/ubuntu wily Release: The following signatures were invalid: DED04C8CBB517AE45B073F12A5D712AEE06E6293

答案1

这电力购买协议 (PPA) 存在问题已过时，其最新支持的 Ubuntu 版本是“wily”（15.10）。您不应在任何当前支持的 Ubuntu 版本上使用此类 PPA。

也可以看看：如果存储库/PPA 没有 Release 文件，我该怎么办？，尤其是N0rbert 的回答可能会对你有帮助。

答案2

我从另一个角度看待这个问题。

在第一种情况下：

deb http://ppa.launchpad.net/upubuntu-com/network/ubuntu wily main
deb-src http://ppa.launchpad.net/upubuntu-com/network/ubuntu wily main

命令：

sudo apt-get update > /dev/null
echo $?

返回错误代码100

In the second case:

deb [trusted=yes] http://ppa.launchpad.net/upubuntu-com/network/ubuntu wily main
deb-src [trusted=yes] http://ppa.launchpad.net/upubuntu-com/network/ubuntu wily main

令我惊讶的是，命令：

sudo apt-get update > /dev/null
echo $?

给我0代码。然后我怀疑并尝试了

sudo apt-get install ipscan

命令确实有效！
