Adobe Air: version number does not start with digit

i'm installing Adobe Air in Ubuntu v11.04. The installation process is successful. But when I tried to install an Adobe Air application, errors occur.

Here's the usual error I've got from my .appdata/Adobe/AIR/Logs/Install.log:

[airinstall:20544][ERR] Error occurred during rpm install operation; 
beginning rollback:ErrorEvent type="error" bubbles=false cancelable=false 
eventPhase=2 text=" error: dpkg: error processing /tmp/FlashTmp.FbSCaL/setup.deb

'V5.01.25.A04111': version number does not start with digit;
Errors were encountered while processing:; /tmp/FlashTmp.FbSCaL/setup.deb" 
errorID=1]

I've followed every instructions here and install as root. What did I've done wrong? According to some forums I've read, this has something to do with the version policy of dpkg but I don't know how to configured dpkg to ignore versioning. Anyone knows how to solve this? Please help me out. Thank you.

Solution

I have successfully installed my air app with no version number does not start with digit error. I just downgraded my dpkg-1.16.0 to dpkg-1.15.8 using the ff command:

dpkg --force-downgrade -i /pathofnewdpkg/dpkg_1.15.8.4ubuntu3_i386.deb

I have downloaded the older package here.

Since the version-policy is enforced on the current version of dpkg, the dpkg-1.16.0, installing an air app that violates this versioning policy of Debian will result to an error.

I have documented the resolution on my newbie dev blog.
