[Not Entirely Solved] errors during making archiso via mkarchiso

The sig files, lets be frank, are surely nonexistent,
Yet when running mkarchiso it will attempt to download *.db.sig from mirrors, causing errors

And that is baseline/pacman.conf :

[options]
HoldPkg     = pacman glibc
Architecture = auto

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

Color
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

[core]
Include = /etc/pacman.d/mirrorlist
[extra]
Include = /etc/pacman.d/mirrorlist
[archlinuxcn]
Include = /etc/pacman.d/mirrorlist_cn

Due to the reason that SigLevel = Required DatabaseOptional doesnt work, I altered it to Never.

Re: [Not Entirely Solved] errors during making archiso via mkarchiso

Re: [Not Entirely Solved] errors during making archiso via mkarchiso

Well, it is useful to add --skip-signature to skip that awful error.
Yet this error shouldnt have existed.

ftfy

Yet this error shouldnt have existed.

Yes "should" …
You also should™ not blog
Please edit your previous post to mend it if nobody has yet replied to not create a false sense of interaction.

And that is baseline/pacman.conf :

https://wiki.archlinux.org/title/Archis … _the_image

create a suitably modified pacman.conf and place it in archlive/airootfs/etc/

If you restore

SigLevel    = Required DatabaseOptional

does that alter the error?
And if you then only constrain archlinuxcn

[archlinuxcn]
SigLevel = Optional TrustAll
Include = /etc/pacman.d/mirrorlist_cn

does that work?
https://wiki.archlinux.org/title/Archis … repository

However
https://wiki.archlinux.org/title/Unoffi … rchlinuxcn

Once the repository is added, archlinuxcn-keyring package must be installed before any other, so you do not get errors about PGP signatures. archlinuxcn-keyring package itself is signed by a developer.

Re: [Not Entirely Solved] errors during making archiso via mkarchiso

Silly, not stupid.

Attempted *what* specifically?

Once mkarchiso runs correctly, it wont crash anymore.

Did that maybe update archlive/airootfs/etc/pacman.conf which now (also) says "SigLevel    = Never"?

To stress that: this is not what you want at all and I very much suspect that the original error would have been different and concerned the archlinuxcn repo.
