Description of problem:

There is a typo in the string construction in blivet/devicelibs/edd.py at line 222:

-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
221         if any([self.fibre_wwid, self.fibre_lun]):
222             s += "%(nl)s%(t)sfibre wwid: %(fibre_wwid)s lun: %s(fibre_lun)s"
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

Fix (no "%s", but "%"):
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
221         if any([self.fibre_wwid, self.fibre_lun]):
222             s += "%(nl)s%(t)sfibre wwid: %(fibre_wwid)s lun: %(fibre_lun)s"
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

This makes installation on FC disks fail with the following exception:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

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

anaconda 29.19.1.13-1.el8 (RHEL 8.1.0 DVD)


How reproducible:

Always on customer system

Steps to Reproduce:

1. Execute python3 interpreter

$ python3
>>> s = "%(nl)s%(t)s fibre wwid: %(fibre_wwid)s lun: %s(fibre_lun)s"
>>> d = {'t': '\t',
    'sysfspath': 'SYSFSPATH',
    'version': 'VERSION',
    'nl': '\n',
    'mbr_sig': 'MBR_SIG',
    'sectors': 'SECTORS',
    'type': 'TYPE',
    'sysfslink': 'SYSFSLINK',
    'host_bus': 'HOST_BUS',
    'pci_dev': 'PCI_DEV',
    'channel': 'CHANNEL',
    'interface': 'INTERFACE',
    'atapi_device': 'ATAPI_DEVICE',
    'atapi_lun': 'ATAPI_LUN',
    'ata_device': 'ATA_DEVICE',
    'ata_pmp': 'ATA_PMP',
    'scsi_id': 'SCSI_ID',
    'scsi_lun': 'SCSI_LUN',
    'usb_serial': 'USB_SERIAL',
    'ieee1394_eui64': 'IEEE1394_EUI64',
    'fibre_wwid': 'FIBRE_WWID',
    'fibre_lun' : 'FIBRE_LUN',
    'i2o_identity': 'I2O_IDENTITY',
    'sas_address': 'SAS_ADDRESS',
    'sas_lun': 'SAS_LUN'
}
>>> s % d

Actual results:

>>> s % d
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: not enough arguments for format string


Expected results:

No exception
