Description Adam Williamson (Fedora) 2015-04-30 19:38:17 UTC
To reproduce: install in any language other than English (I tested with French but I think it affects all cases where translation kicks in) and choose to encrypt the install. Once the encryption passphrase dialog pops up, start typing. Cue crash. Traceback:

Traceback (most recent call first):
  File "/usr/lib64/python2.7/site-packages/pyanaconda/ui/gui/spokes/lib/", line 171, in _checkStrength
    return ("dialog-error", _(ERROR_WEAK) % self._pwq_error)
  File "/usr/lib64/python2.7/site-packages/pyanaconda/ui/", line 250, in update_check_status
    new_check_status = self._run_check(self)
  File "/usr/lib64/python2.7/site-packages/pyanaconda/ui/gui/", line 42, in _update_check_status
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 42: ordinal not in range(128)

This is related to the infamous and (fun with locales and encodings in the live environment).

Proposing as a Final blocker: "The installer must correctly display all sufficiently complete translations available for use." , (alternatively, any of the 'complete an install' criteria in the case that the install is live and in something other than English).

We've tested that this fixes it:

     def _checkStrength(self, inputcheck):
         if self._pwq_error:
-            return ("dialog-error", _(ERROR_WEAK) % self._pwq_error)
+            return ("dialog-error", _(ERROR_WEAK).encode('utf-8') % self._pwq_error)
             return InputCheck.CHECK_OK

there are likely other cases, though. I would think that any time we use a %s substitution into a translated string and the translation has non-ASCII characters in it would fail, but that doesn't actually seem to be the case: I tested a few others (like "error = _("%s cannot be encrypted") % mountpoint" in and "return _(PASSWORD_WEAK_WITH_ERROR) % (self._pwq_error, done_msg)" in and they didn't cause crashes. IIRC there's some kind of wrinkle involved where Python *does* somehow know to use utf-8 in some cases but not others, but I'm not sure we ever fully traced that out.

Comment 2 Adam Williamson (Fedora) 2015-04-30 20:48:41 UTC
See also - apparently the behaviour of %s as it relates to unicode objects is...unclear (and I'm not sure why it fails in this case, given the information from that bug - perhaps something odd about pwquality.PWQError objects?)

Comment 3 Dan Mossor [danofsatx] 2015-05-04 16:39:40 UTC
Discussed at the 2015-05-04 blocker review meeting.[0] Voted as AcceptedBlocker based on different criteria as cited in Comment #1.

AcceptedBlocker - violates "When using the guided partitioning flow, the installer must be able to:  ...  Complete an installation using any combination of disk configuration options it allows the user to select" for live, non-English installs
