I am running lucid, and would like to upgrade to precise. I have changed the settings in Update Manager to "Long term support releases only", but I only get the option "New Ubuntu release '10.10' is available". I thought it was possible to upgrade directly from one LTS to the next (i.e. go direct from lucid to precise). Is that right, or would I have to go through all the intermediate versions?
To add some extra details, running "lsb_release -a" gives: No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 10.04.4 LTS Release: 10.04 Codename: lucid
In /etc/update-manager/release-upgrades I have Prompt=lts
Running do-release-upgrade gives the output:
Checking for a new ubuntu release
Failed Upgrade tool signature
Failed Upgrade tool
Done downloading
Failed to fetch
Fetching the upgrade failed. There may be a network problem.

In shell, this is just a simple apt-get command. First update the lists and upgrade any packages:
sudo apt-get update
sudo apt-get upgradeAnd then upgrade your distribution:
sudo apt-get dist-upgrade(Might take a while!)
If that doesn't work you need to use update manager:
sudo aptitude install update-manager-core
sudo do-release-upgradeCan you confirm you're on Lucid:
lsb_release -aShould report four lines with 10.04 and lucid in there. Next thing is you need upgrade manager to move to the next LTS, not 10.10 which you mention above... vi /etc/update-manager/release-upgrades
Prompt=ltsTry and run do-release-upgrade again, if you could paste out the actual fail message (in your Q) it'd be helpful too.
Hi I came upon this thread while trying to do an upgrade from Lucid to Precise and I was getting the same error:
Checking for a new Ubuntu release
Failed Upgrade tool signature
Failed Upgrade tool
Done downloading
Failed to fetch Fetching the upgrade failed.
There may be a network problem.I found the issue in my /etc/apt/apt.conf file
I had to comment out this statement:
Acquire::http::Proxy "";Once commented out, running do_release_update worked for me.
