我想知道什么
"${distro_id}ESM:${distro_codename}";在50无人值守的升级文件中。默认情况下,它是为我启用的(在对无人值守的包进行标记之后--至少升级包)。现在,我禁用了它,只为自动升级启用了-security,但是我想了解它是什么,再一次取消注释是否更好。
这是它所在的街区;
Unattended-Upgrade::Allowed-Origins { //
"${distro_id}:${distro_codename}";
"${distro_id}:${distro_codename}-security";
// Extended Security Maintenance; doesn't necessarily exist for
// every release and this system may not have it installed, but if
// available, the policy for updates is such that unattended-upgrades
// should also install from here by default.
// "${distro_id}ESM:${distro_codename}";
// "${distro_id}:${distro_codename}-updates";
// "${distro_id}:${distro_codename}-proposed";
// "${distro_id}:${distro_codename}-backports";
};在我启用-updates、-proposed、-backports之前,是否应该启用某种母亲?
非常感谢。

这是规范的扩展安全维护为LTS发布后,正常发布结束.目前,除非您使用12.04并支付费用,否则它不适用于您。
