我不记得为什么我有 download.opensuse.org,但我只要删除导致此错误的内容就可以了:
W: GPG error: http://download.opensuse.org Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6FE3AE1CC7D68E37
这似乎不是一个重复的问题,因为其他类似问题中提出的解决方案在这里不起作用:
# sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6FE3AE1CC7D68E37
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /tmp/tmp.OCmHCQ908W --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keyserver.ubuntu.com --recv-keys 6FE3AE1CC7D68E37
gpg: requesting key C7D68E37 from hkp server keyserver.ubuntu.com
gpgkeys: key 6FE3AE1CC7D68E37 not found on keyserver
gpg: no valid OpenPGP data found.

我现在是 12.04
答案1
我忽略了 sources.list 中的这个条目:
deb http://download.opensuse.org/repositories/home:ksmanis/xUbuntu_12.04/ /
删除那行就是我正在寻找的答案。
然而,找到该条目后,我就能找到它存在的原因以及更好的解决方法:
