reposync debug output

Description of problem:

reposync with installroot specified fails when repo file contains repo_gpgcheck=1. When I comment out that directive it works fine.



Version-Release number of selected component (if applicable):

# rpm -qa python3-dnf
python3-dnf-4.4.2-11.el8.noarch


How reproducible:

I'm doing this:
> sudo su - repoman
> pubrepoadm distro sync -n pgdg14

pubrepoadm is a script which calls:

reposync -c /data/yumrepos/public/distroroot/common-8/etc/dnf.conf -p /data/yumrepos/public/pkgmirror/common/8/x86_64 -g -n --download-metadata --remote-time --repoid=pgdg14

There is installroot specified in that dnf.conf. The repo file contains this:

[pgdg14]
name=PostgreSQL 14 for RHEL/CentOS $releasever - $basearch
baseurl=https://download.postgresql.org/pub/repos/yum/14/redhat/rhel-$releasever-$basearch
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG
repo_gpgcheck = 1

I'm getting:

Errors during downloading metadata for repository 'pgdg14':
  - Curl error (37): Couldn't read a file:// file for file:///etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG [Couldn't open file /etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG]
Error: Failed to retrieve GPG key for repo 'pgdg14': Curl error (37): Couldn't read a file:// file for file:///etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG [Couldn't open file /etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG]

I've tried with --installroot instead of -c and with both of them specified, but
the result is the same.

Debug output with '-d 10' is in the attachment.

Contents of dnf.conf in installroot:

[main]
installroot=/data/yumrepos/public/distroroot/common-8
# This should probably be removed for CentOS 8 because it's logging in
# reporoot.
logfile=/var/log/repoman/dnf.log
keepcache=0

payload_gpgcheck=1
gpgcheck=1

assumeno=1

installonly_limit=3
clean_requirements_on_remove=True
best=True
skip_if_unavailable=False


The default OS directory does not contain the GPG key mentioned in the error message:
# ls /etc/pki/rpm-gpg 
RPM-GPG-KEY-AlmaLinux  RPM-GPG-KEY-EPEL-8

But it is present in the installroot:
# ls /data/yumrepos/public/distroroot/common-8/etc/pki/rpm-gpg 
RPM-GPG-KEY-elrepo.org  RPM-GPG-KEY-jenkins  RPM-GPG-KEY-SALTSTACK
RPM-GPG-KEY-EPEL-8      RPM-GPG-KEY-nginx
RPM-GPG-KEY-grafana     RPM-GPG-KEY-PGDG

All those keys are imported in the respective keyrings (OS default in the OS keyring and installroot keys in the installroot keyring).

It seems to me that reposync attempted to fetch the GPG key file from the OS path /etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG instead from that path inside installroot.

I'm also attaching dnf.librepo.log from the installroot. It doesn't have additional information, though.

Steps to Reproduce:


1. Create minimal installroot necessary for reposync to function
2. Add the above repo file
3. Run reposync

If I comment out repo_gpgcheck directive everything works fine.

Actual results:

Execution is aborted.

Expected results:

reposync should be able to do its thing without an error.

Additional info:

In the debug output there is:

Failed to create directory "/run/user/1104": 13 - Permission denied

1104 is the UID for repoman user. I've created that directory manually, but the result is the same. The only difference is that an empty directory named gnupg is created there.
