## Description
When invoking `cbs` on Fedora 44, the command exits with an authentication error:
```
$ cbs build --scratch storage10s-samba-424-el10s SRPMS/samba-4.24.2-200.el10s.src.rpm
2026-05-19 10:44:59,011 [ERROR] koji: AuthError: Server CA /etc/pki/tls/certs/ca-bundle.trust.crt doesn't exist or is not accessible
```
#### Additional notes
```
$ rpm -q centos-packager
centos-packager-0.7.0-19.fc44.noarch
$ rpm -q ca-certificates
ca-certificates-2025.2.80_v9.0.304-7.fc44.noarch
$ rpm -qil ca-certificates | grep ca-bundle.trust.crt
/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
/etc/ssl/certs/ca-bundle.trust.crt
$ ls -l /etc/ssl/certs/ca-bundle.trust.crt
lrwxrwxrwx. 1 root root 55 Apr 1 05:30 /etc/ssl/certs/ca-bundle.trust.crt -> /etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
$ cat /etc/koji.conf.d/cbs-koji.conf
[cbs]
;url of XMLRPC server
server = https://cbs.centos.org/kojihub/
;url of web interface
weburl = https://cbs.centos.org/koji
;url of package download site
topurl = http://cbs.centos.org/kojifiles
;path to the koji top directory
topdir = /mnt/koji
;client certificate
cert = ~/.centos.cert
;certificate of the CA that issued the HTTP server certificate
serverca = /etc/pki/tls/certs/ca-bundle.trust.crt
```
Once the `serverca` location is updated in _/etc/koji.conf.d/cbs-koji.conf_ the `cbs` command runs successfully.
