[解决了但没有完全解决] archiso制作报错*.db.sig不存在

技术交流与探讨 应用程序与桌面环境

确实不存在sig文件 但是make iso的时候仍然会下载sig文件 然后由于不存在而报错退出

难不成需要自行劫持dns 手动提供可用的sig文件？

已尝试的措施：siglevel设置为never 执行pacman-key --populate archlinux

SigLevel = Required DatabaseOptional 应该就好了。你看看你的/home/thispc/livecd/baseline/pacman.conf里是怎么写的？

baseline/pacman.conf

[options]
HoldPkg     = pacman glibc
Architecture = auto

# Pacman won't upgrade packages listed in IgnorePkg and members of IgnoreGroup
#IgnorePkg   =
#IgnoreGroup =

CheckSpace
VerbosePkgLists
ParallelDownloads = 16
DownloadUser = alpm

# By default, pacman accepts packages signed by keys that its local keyring
# trusts (see pacman-key and its man page), as well as unsigned packages.
SigLevel    = Never
#LocalFileSigLevel = Optional
#RemoteFileSigLevel = Required

更改为RDO之后报错相同

好怪啊，为什么.db.sig下载失败不会忽略呢……

6

目前只能手动添加--skip-signature参数来规避此问题

很好奇为什么不添加sig文件同时还在保留这个抽象的sig校验

7

最神奇的来了

装了个vm测试 一样的配置文件 一点错没报

顺带一提enBBS的阴阳程度 :melting_face:
