fakeroot: preload library `libfakeroot-sysv.so' not found, aborting.

[solsticedhiver]

I am trying to use a custom AppImageBuilder.yml (taken from https://appimage-builder.readthedocs.io/en/latest/examples/flutter.html and modified to run with pacman):

# appimage-builder recipe see https://appimage-builder.readthedocs.io for details
version: 1
script:
 - rm -rf AppDir || true
 - cp -r build/linux/x64/release/bundle AppDir
 - mkdir -p AppDir/usr/share/icons/hicolor/64x64/apps/
 - cp flutter-mark-square-64.png AppDir/usr/share/icons/hicolor/64x64/apps/
AppDir:
  path: ./AppDir
  app_info:
    id: org.appimagecrafters.flarte
    name: Flarte
    icon: flutter-mark-square-64
    version: latest
    exec: flarte
    exec_args: $@
  pacman:
    Architecture: x86_64
    repositories:
      core:
        - http://ymir:9129/repo/archlinux_x86_64/$repo/os/$arch
    include:
      - bash
    exclude:
      - perl
    options:
      # don't check package signatures
      SigLevel: "Optional TrustAll"
  files:
    exclude:
    - usr/share/man
    - usr/share/doc/*/README.*
    - usr/share/doc/*/changelog.*
    - usr/share/doc/*/NEWS.*
    - usr/share/doc/*/TODO.*
  test:
    fedora:
      image: appimagecrafters/tests-env:fedora-30
      command: ./AppRun
      use_host_x: true
    debian:
      image: appimagecrafters/tests-env:debian-stable
      command: ./AppRun
      use_host_x: true
    arch:
      image: appimagecrafters/tests-env:archlinux-latest
      command: ./AppRun
      use_host_x: true

      command: ./AppRun
      use_host_x: true
AppImage:
  arch: x86_64

  sign-key: None

and this throws this error:

on archlinux with appimage-builder: 1.1.1.dev32+g2709a3b using the AppImage version installed in /opt via appimage-builder-bin pacakge

Works better by using the python version installed via pip in a virtualenv. Ends up in another (unrelated error)

FileExistsError: [Errno 17] File exists: 'usr/lib' -> '/tmp/AppDir/lib'

I ran into the same issue with the AUR appimage-builder-bin package. Using the appimage-builder installed via pip works just fine with my python project. So this might be a packaging issue.

The AUR package is based on the AppImage-file provided here. It tries to load libraries named in the Debian way. So if you create the corresponding links some errors go away. But it still does not work properly, as it requires root access.

cd /usr/lib/libfakeroot
sudo ln -s libfakeroot-0.so libfakeroot-sysv.so

cd /usr/bin
sudo ln -s faked faked-sysv
sudo ln -s fakeroot fakeroot-sysv

@skcin it's a packaging issue, the fakeroot in the bundle is not compatible with the libfakeroot on the system. If I bundle that lib too it doesn't work either (or at least I wasn't able to make it work).

I proposed solution to package maintainer, lets wait until he accepts

@solsticedhiver this issue can be closed safely

I tried this and it sort of works but now i get another error

==> Updating trust database...
gpg: no need for a trustdb check
gpg: starting migration from earlier GnuPG versions
gpg: can't connect to the agent: File name too long
gpg: error: GnuPG agent unusable. Please check that a GnuPG agent can be started.
gpg: migration aborted

I tried running pacman-key --init on my system but it didn't work and i tried adding it as a script in the top of the file and it also didn't work

script:
  - pacman-key --init

does this tool just doesn't work on Arch?
