I also tried to run mock with --no-bootstrap-chroot. Same error occurred.

Rgrds,

That would be good guess, with '--no-bootstrap-chroot'.  But nowadays there are
two steps by default:

  * Host RPM/DNF installs target RPM/DNF into "bootstrap" chroot
  * RPM/DNF from bootstrap is used to install the final chroot

And so the gpg keys need to be available in bootstrap chroot, and
sometimes also on host, depending on use-case.

There's a mock's internal method [1] which copies GPG keys into both
bootstrap and normal chroot, but it only looks at
/usr/share/distribution-gpg-keys - so the easiest way is to put the custom
GPG keys there.  Sometimes it might be a good idea to talk to
distribution-gpg-keys [2] maintainer (Mirek Suchý) and include the keys
there by default.

The point is that mock has to be able to install into empty chroots and 
that's why it's using package manager and configuration from the host 
environment.

Hallo,

I have the following problem: I'm trying to install rpm packages, signed 
with my local key, into mock chroot.

I use the following procedure:

   Create chroot:
       mock --arch=x86_64 -r rpm/cs8.cfg --init
   Copy my rpm key file into chroot:
       mock --arch=x86_64 -r rpm/cs8.cfg --cache-alterations --copyin 
/etc/pki/rpm-gpg/Local-KEY /etc/pki/rpm-gpg
   Install my package into chroot:
       mock --arch=x86_64 -r rpm/cs8.cfg --cache-alterations --install 
my-rpm-package

During package install I get the following error:

   Curl error (37): Couldn't read a file:// file for 
file:///etc/pki/rpm-gpg/Local-KEY [Couldn't open file 
/etc/pki/rpm-gpg/Local-KEY]

I check chroot contents with:
   mock --arch=x86_64 -r rpm/cs8.cfg --shell "ls -l 
/etc/pki/rpm-gpg/Local-KEY"

and it shows me that the file is present. I doublecheck with:

   ls -l /var/lib/mock/cs8/root/etc/pki/rpm-gpg

and this also shows that file is present. The file is also present on 
host system in /etc/pki/rpm-gpg

What I'm doing wrong?

Best regards,
