我使用 在 AWS Cloud9 机器内运行 Manjaro 容器docker container run --interactive --tty manjarolinux/build bash，我运行的第一个命令pacman -Syy失败并显示以下输出：
# pacman -Syy
:: Synchronizing package databases...
error: failed retrieving file 'packages.db' from disk : Couldn't open file /build/packages/packages.db
error: failed to update packages (download library error)

/build/目录为空，因此该文件不存在。该文件的用途是什么？我该如何解决这个问题？
我需要在容器中安装包，但 pacman 现在似乎没用。
/etc/pacman.conf：

# 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 = Required DatabaseOptional
LocalFileSigLevel = Optional
#RemoteFileSigLevel = Required
# NOTE: You must run `pacman-key --init` before first using pacman; the local
# keyring can then be populated with the keys of all official Manjaro Linux
# packagers with `pacman-key --populate archlinux manjaro`.
#
# REPOSITORIES
# - can be defined here or included from another file
# - pacman will search repositories in the order defined here
# - local/custom mirrors can be added here or in separate files
# - repositories listed first will take precedence when packages
# have identical names, regardless of version number
# - URLs will have $repo replaced by the name of the current repo
# - URLs will have $arch replaced by the name of the architecture
#
# Repository entries are of the format:
# [repo-name]
# Server = ServerName
# Include = IncludePath
#
# The header [repo-name] is crucial - it must be present and
# uncommented to enable the repo.
#
[packages]
SigLevel = Optional TrustAll
Server = file:///build/packages
[core]
Include = /etc/pacman.d/mirrorlist
[extra]
Include = /etc/pacman.d/mirrorlist
[community]

# If you want to run 32 bit applications on your x86_64 system,
# enable the multilib repositories as required here.

# An example of a custom package repository. See the pacman manpage for
# tips on creating your own repositories.

答案1
注释掉关于自定义 repos 的 3 行。
[packages]
SigLevel = Optional TrustAll
Server = file:///build/packages
如果您从未修改过它。我不知道为什么要设置自定义存储库。但您肯定不使用自己的存储库。因此必须对自定义存储库进行注释。
