Solve the following python programming problem given the following code:
def testSignedUpdate(self) : 
    fingerprint = '95B457D16843B21EA3FC73BBC7C32FC1F94E405E' 
    keyCache = openpgpkey.getKeyCache () 
    keyCache.getPrivateKey (fingerprint, '111111') 
    self.addQuickTestComponent ('test:doc', '1.0-1-1') 
    self.cfg.signatureKey = fingerprint 
    self.cfg.quiet = True 
    keyRing = open (resources.get_path ('conary_test', 'archive', 'pubring.gpg')) 
    keyData = openpgpfile.exportKey (fingerprint, keyRing) 
    keyData.seek (0) 
    keyData = keyData.read () 
    repos = self.openRepository () 
    repos.addNewPGPKey (repos.cfg.buildLabel, 'test', keyData) 
    signtrove.signTroves (self.cfg, ['test:doc']) 
    pubKey = keyCache.getPublicKey (fingerprint) 
    pubKey.trustLevel = openpgpfile.TRUST_UNTRUSTED 
    keyCache.publicDict [fingerprint] = pubKey 
    self.cfg.trustThreshold = openpgpfile.TRUST_ULTIMATE 
    self.logFilter.add () 
    try : 
        self.discardOutput (doUpdate, self.cfg, 'test:doc') 
        self.fail ('updatecmd.doUpdate did not properly check trust levels') 
except DigitalSignatureVerificationError : 
        self.logFilter.compare (['warning: The trove test:doc has signatures generated with untrusted keys.

class MyException (Exception) : 
        errorIsUncatchable = True
