Description of problem:
When running reposync for multiple during multiple days downloading rpms to the same dir (to keep a local copy up of the repos up to date) I'm seeing that from time to time it starts failing to download some rpm with the error:

python-ioprocess-0.15.0-4.el7. FAILED                                          
python-ioprocess-0.15.0-4.el7.noarch: [Errno 256] No more mirrors to try.


Version-Release number of selected component (if applicable):
# rpm -qa yum-utils
yum-utils-1.1.31-508.fc23.noarch


How reproducible:
You can use this yum config:

# cat test.repo 
[main]
reposdir=/etc/reposync.repos.d
retries=3
debuglevel=10
rpmverbosity=debug
[epel-el7]
name=EPEL repo
baseurl=https://dl.fedoraproject.org/pub/epel/7/x86_64/
enabled=1
gpgcheck=0


Then run reposync:

 "reposync" "--config=test.repo" "--download_path=/tmp/reposync" "--newest-only" "--delete" "--cachedir=/tmp/reposync_cache"  "--repoid=epel-el7"


If eventually (usually the day after) reposync will start failing, even though it has the rpm there:

# tree /tmp/reposync
/tmp/reposync
└── epel-el7
    ├── g
    ├── i
    ├── l
    ├── m
    ├── p
    │   └── python-ioprocess-0.15.0-4.el7.noarch.rpm
    └── s

If you remove the rpm manually, it redownloads it and continues successfully.

Steps to Reproduce:
1.
2.
3.

Actual results:
Reposync complains about being unable to download from any mirrors and fails

Expected results:
Reposync succeeds, either

The rpm it's replaced by once you remove it:
[root@dev-20 ovirt-system-tests]# rm /tmp/reposync/epel-el7/p/python-ioprocess-0.15.0-4.el7.noarch.rpm
rm: remove regular file ‘/tmp/reposync/epel-el7/p/python-ioprocess-0.15.0-4.el7.noarch.rpm’? y
[root@dev-20 ovirt-system-tests]# "reposync" "--config=test.repo" "--download_path=/tmp/reposync" "--newest-only" "--delete" "--cachedir=/tmp/reposync_cache"  "--repoid=epel-el7" 

Yum-utils package has been deprecated, use dnf instead.
