[CentOS] dnf and failing epel

hi everyone,

I use dnf but one epel fails in a peculiar way:

$ dnf repolist
Failed to open: 
/var/cache/dnf/x86_64/7/x86_64/7/epel/repodata/8415cbb16f52517f34e3edac12a97c9893117f7b9de6cb22fc086048febd1c60-updateinfo.xml.bz2.

that file is there, so I tampered with perms & fcontext but 
to no avail. dnf clean does remove it but on the first 
contact to epel repo it fails again.
Do you see it with your centoses?

ps. I wonder if my email get though to the group, I receive 
mailing list emails but I don't get my own emails?

b.w.
