1、有时候想更新系统,发现更新失败 sudo apt-get update 2、这时候可以考虑更新系统源,因为ubuntu默认的网站应该是境外的,速度慢而且可能被墙 可以从清华镜像官网获取系统源:ubuntu清华镜像网站 3、备份原来的更新源 cp /etc/apt/sources.list /etc/apt/sources.list.bk 4、sudo权限打开更新源配置文件,将清华的更新源替换 sudo vi /etc/apt/sources.list # 默认注释了源码镜像以提高 apt update 速度,如有需要可自行取消注释 deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse # 预发布软件源,不建议启用 # deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse 5、保存成功后,再次更新 sudo apt-get update -y 6、此时还是有可能更新不成功,如我自己碰到的, 因为是因为没有公钥,需要下载一份,执行命令: 看网友的案例,有些可能需要下图的两个公钥不一样,所以需要下载两个公钥 sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com FCEF32E745F2C3D5 mi@mi-OptiPlex-7040:~/work/paipai$ sudo apt-get update -y 命中:1 http://ppa.launchpad.net/git-core/ppa/ubuntu xenial InRelease 命中:2 http://ppa.launchpad.net/notepadqq-team/notepadqq/ubuntu xenial InRelease 获取:3 https://mirrors.tuna.tsinghua.edu.cn/ubuntu focal InRelease [265 kB] 错误:15 http://pkg.jenkins-ci.org/debian-stable binary/ Release.gpg 由于没有公钥,无法验证下列签名: NO_PUBKEY FCEF32E745F2C3D5 获取:17 https://mirrors.tuna.tsinghua.edu.cn/ubuntu focal/restricted i386 Packages [8,112 B] 获取:18 https://mirrors.tuna.tsinghua.edu.cn/ubuntu focal/restricted Translation-zh_CN [1,324 B] 获取:70 https://mirrors.tuna.tsinghua.edu.cn/ubuntu focal-security/universe DEP-11 64x64 Icons [46.0 kB] 获取:71 https://mirrors.tuna.tsinghua.edu.cn/ubuntu focal-security/multiverse amd64 Packages [14.8 kB] 获取:72 https://mirrors.tuna.tsinghua.edu.cn/ubuntu focal-security/multiverse i386 Packages [2,520 B] 获取:73 https://mirrors.tuna.tsinghua.edu.cn/ubuntu focal-security/multiverse Translation-en [3,160 B] 已下载 40.9 MB,耗时 1分 56秒 (350 kB/s) (appstreamcli:27147): GLib-CRITICAL **: g_strchug: assertion 'string != NULL' failed (appstreamcli:27147): GLib-CRITICAL **: g_strchomp: assertion 'string != NULL' failed AppStream cache update completed, but some metadata was ignored due to errors. 正在读取软件包列表... 完成 W: 校验数字签名时出错。此仓库未被更新,所以仍然使用此前的索引文件。GPG 错误:http://pkg.jenkins-ci.org/debian-stable binary/ Release: 由于没有公钥,无法验证下列签名: NO_PUBKEY FCEF32E745F2C3D5 W: 无法下载 http://pkg.jenkins-ci.org/debian-stable/binary/Release.gpg 由于没有公钥,无法验证下列签名: NO_PUBKEY FCEF32E745F2C3D5 W: 部分索引文件下载失败。如果忽略它们,那将转而使用旧的索引文件。 7、再次更新: sudo apt-get update -y zhuyi: 解决 E: Could not get lock /var/lib/apt/lists/lock1.https://www.cnblogs.com/qq952693358/p/6537846.html 2.also can restart the system
