I have an old desktop version (9.10) and want to upgrade to 10.04. Due to firewall restrictions (company policy), I can't use the regular upgrade (via synaptic or apt-get). I decided to use the alternate iso and launched cdromupgrade. I got the following message (sorry for the translation):
Your system is up to date
No upgrade is available for your system
The upgrade will be cancelled
I don't understand why it tells that the system is up to date as the current version is 9.10 and I want to upgrade to 10.04.
I use ubuntu-10.04.4-alternate-i386.iso
Thanks in advance for your ideas
