ubiquity crashed with UnicodeDecodeError in decode_ssid(): 'ascii' codec can't decode byte 0xe9 in position 15: ordinal not in range(128)

This happened to me as well the moment I clicked the installation icon on the desktop. Live session from USB, Ubuntu 11.10 Beta 1 AMD64.

is there a temporary work around which will allow to install ubuntu when this error happens ?

Do you try to access a wireless network where a SSID contains non-ascii characters ?

I don't think so, but fwiw I brought the disk on a business trip and successfully installed from the hotel's wireless network.

No, the ssid was " tytur-byose-net "

The SSID of the network I was trying to connect to was "Jacobs-Bols", so not non-ASCII characters in there either.

This is in build_cache, so there only has to be *any visible AP* with non-ASCII characters for this to break.

I'll take this.

This bug was fixed in the package ubiquity - 2.8.0

---------------
ubiquity (2.8.0) oneiric; urgency=low

  * Fix SSID UTF-8 decoding, and replace any still-invalid characters with
    the Unicode replacement character just in case (LP: #839143).
  * GTK frontend:
    - Fetch geoname data asynchronously (LP: #837217).
  * Always start oem-config with LANG=en_US.UTF-8; this doesn't affect
    translations since we use debconf for those, but forces Qt to use UTF-8
    encoding for text fields (LP: #837042).

Petr, yours was actually a slightly different bug triggered by a recent change to dbus-python. See bug 922988.
