[SOLVED] Errors installing pacman from source files

hmogni · 2020-01-20 18:11:12

I did compile pacman from source files (autoconf, ./configure, make, sudo make install). first when I tried to install a given package I got

error: failed to commit transaction (invalid or corrupted package (PGP signature).

. when I run pacman-key --populate archlinux I get this error

error: The keyring file /usr/local/share/pacman/keyrings/archlinux.gpg does not exist

after some research I found in another thread that I needed the archlinux-keyring package (after setting SigLevel = Never in pacman.conf)

here is what I get

sudo pacman -S archlinux-keyring

#     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:

#       Include = IncludePath
#
# The header [repo-name] is crucial - it must be present and
# uncommented to enable the repo.

# The testing repositories are disabled by default. To enable, uncomment the
# repo name header and Include lines. You can add preferred servers immediately
# after the header, and they will be used before the default mirrors.

Yes you have a distinct pacman database trying to overwrite existing files (from another database). What exactly is the point of this exercise?

hmogni · 2020-01-20 18:36:08

I'm intending to learn about pacman's source code; editing, compiling, running...etc.

Install and set up in a chroot then, right now you have conflicts with your self compiled database and it wanting to install "new files" that are already part of your normal system: https://wiki.archlinux.org/index.php/De … ean_chroot

or of course reconfigure it to use the system's database, but depending on what you want to "experiment" with, it's likely safer to do so in an isolated system.

ok thank you for your answers. I uninstalled my compiled version of pacman and will be *experimenting* in a chroot environment from now on.

Conf File : /usr/local/etc/pacman.conf
DB Path : /usr/local/var/lib/pacman/
Cache Dirs: /usr/local/var/cache/pacman/pkg/
Hook Dirs : /usr/local/share/libalpm/hooks/ /usr/local/etc/pacman.d/hooks/
Lock File : /usr/local/var/lib/pacman/db.lck
Log File : /usr/local/var/log/pacman.log
GPG Dir : /usr/local/etc/pacman.d/gnupg/

All your configs are pointing to ./configure --prefix=/usr/local and corresponding annoying defaults for e.g. sysconfdir/localstatedir. You'd ideally want to use the same pacman database as your real pacman version, but merely swap out your pacman binary.

e.g. your GPG Dir was empty, while the one installed with arch linux itself has the keys.

The official packages use: --prefix=/usr --sysconfdir=/etc --localstatedir=/var, which you'll probably also want to do. You can modify the PKGBUILD in core, or use pacman-git in the AUR, in order to build a package that uses your own modified pacman sources.

Another option for local development is to configure using --prefix=/usr --sysconfdir=/etc --localstatedir=/var, but instead of using make install, run pacman directly from the build tree via ./src/pacman/pacman

thank you eschwartz for your thorough explanation. That helped clearing up how things works!
