Dear All:

I a new to Tahoe and am trying to experiment it on a desktop with
ubuntu. However, I cannot get all the self-test cases passed. Any
advice will be highly appreciated.

Here is my environment:
allmydata-tahoe: 1.8.0, foolscap: 0.5.1, pycryptopp: 0.5.25, zfec:
1.4.7, Twisted: 10.1.0, Nevow: 0.10.0, zope.interface: 3.6.1, python:
2.6.6, platform: Linux-Ubuntu_10.10-x86_64-64bit_ELF, sqlite: 3.7.2,
simplejson: 2.1.1, argparse: 1.1, pycrypto: 2.0.1, pyOpenSSL: 0.10,
pyutil: 1.7.12, zbase32: 1.1.2, setuptools: 0.6c16dev2, pyasn1:
0.0.11a, pysqlite: 2.4.1

Here is the error output:
===============================================================================
[SKIPPED]: allmydata.test.test_encodingutil.StdlibUnicode.test_open_unrepresentable

This test cannot be run unless we know a filename that is not representable.
===============================================================================
[SKIPPED]: allmydata.test.test_encodingutil.Windows.test_listdir_unicode

This platform does not support the 'mbcs' filesystem encoding that we
are testing for the benefit of a different platform.

[SKIPPED]: allmydata.test.test_provisioning.Reliability.test_basic

reliability model requires NumPy
===============================================================================
[SKIPPED]: allmydata.test.test_storage.Server.test_large_share

This test can spuriously fail if you have less than 4 GiB free on your
filesystem, and if your filesystem doesn't support efficient sparse
files then it is very expensive (Mac OS X and Windows don't support
efficient sparse files).
