更新linux时候提示“由于没有公钥,无法验证下列签名".
本文链接:https://blog.csdn.net/loovejava/article/details/21837935
新安装的Ubuntu在使用sudo apt-get update更新源码的时候出现如下错误:
W: GPG 错误:http://ppa.launchpad.net precise Release: 由于没有公钥,无法验证下列签名: NO_PUBKEY 3EE66BD3F599ACE3
W: GPG 错误:http://ppa.launchpad.net precise Release: 由于没有公钥,无法验证下列签名: NO_PUBKEY 6AF0E1940624A220
W: 无法下载 bzip2:/var/lib/apt/lists/partial/mirrors.163.com_ubuntu_dists_precise_main_binary-i386_Packages Hash 校验和不符
W: 无法下载 bzip2:/var/lib/apt/lists/partial/mirrors.163.com_ubuntu_dists_precise-security_main_binary-i386_Packages Hash 校验和不符
W: 无法下载 bzip2:/var/lib/apt/lists/partial/extras.ubuntu.com_ubuntu_dists_precise_main_binary-amd64_Packages Hash 校验和不符
W: 无法下载 bzip2:/var/lib/apt/lists/partial/extras.ubuntu.com_ubuntu_dists_precise_main_binary-i386_Packages Hash 校验和不符
E: Some index files failed to download. They have been ignored, or old ones used instead.
解决方法很简单,下载导入公钥就行,下载导入key的命令如下:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6AF0E1940624A220 #此处6AF0E1940624A220需要是错误提示的key
此时继续更新发现没有公钥错误提示,但是还是效验存在问题,此时需要打开软件源的界面,将其他软件选项中的Canpnical合作伙伴/独立等四个选项取消勾选,再执行sudo apt-get update
此时发现可以顺利更新了。
sanbo@ubuntu:~/dev$ sudo apt-get update
搞定收工!
另外送上一个163源,更新的速度挺不错,品种也挺全的:

==============================================偶尔时刻还是有各种问题,归纳如下================================================
【缺少公钥】
现象:
sudo apt-get update
W: GPG error: http://apt.tt-solutions.com dapper Release: 由于没有公钥,下列签名无法进行验证: NO_PUBKEY 06EA41DE4F6C1E86
解决方法:
gpg --keyserver subkeys.pgp.net --recv 4F6C1E86
gpg --export --armor 4F6C1E86 | sudo apt-key add -
说明:
若缺少其他公钥,则将命令中两处4F6C1E86改为NO_PUBKEY
06EA41DE4F6C1E86中最后8位即可!
如果是Ubuntu PPA的则按照如下方法处理:
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com
【签名错解决办法】
情况一.概率出现的问题,这次有,可能下次就没了,可忽略
By simply waiting. This happens at times during archive updates.
情况二.使用如下方法更新:
$ sudo apt-get update -o Acquire::http::No-Cache=True
或者
$ sudo apt-get update -o Acquire::BrokenProxy=true
情况三.
现象:
In a particular case this was caused by a broken file and could get fixed using rescue boot and "fsck -fy /" (http://forum.ubuntuusers.de/goto?post=89197 - german)
解决办法:
fsck -fy /
情况四:
现象:
The fix is just to back up sources.list, delete everything in it and run "apt-get update". After the update replace sources.list with the backup and run "apt-get update" again. You should not get the error then.
解决办法:
备份sources.list,然后把sources.list中的东西删空,运行"apt-get update",然后再用刚刚的备份将"apt-get update"复原,再运行"apt-get update"。
情况五.主旨就是清理缓存
sudo bash
apt-get clean
cd /var/lib/apt
mv lists lists.old
mkdir -p lists/partial
apt-get clean
apt-get update
情况六.缓存代理服务器导致的问题:
如下内容添加到/etc/apt/apt.conf.d/10broken_proxy文件里试试看。
Acquire::http::No-Cache "true";
Acquire::http::Max-Age "0";
情况七
sudo apt-get install medibuntu-keyring
