Simply run "update-manager -d" and Update Manager will be forced to
check whether an upgrade is available.

> At the top of the page mentioned above, the steps to be done have been

>> set release upgrades to be for normal releases instead of LTS releases
>> run the release upgrade tool
>> reboot

> Though you did already the first step,  do it again - simply to fire up the

> Second step. Do not wait for the new version update notifier, but carry out

> date. Do so best via a terminal:
> sudo aptitude update.
> Wait for the update check to finish while staying in the same terminal. Now,
>
> give in another unix command:
> sudo aptitude safe-upgrade
> If you do not have "aptitude", install it first:
> sudo apt-get install aptitude.
> At the end of the update process, you will be prompted for Y/N: to update or
>
> not to update :-). Give in Y, wait for the process to finish and close the
> terminal.
>
>
> Third step. If the upgrade notifyer pops up, click at it and follow the
> instructions that will come to you. If not, go to K-Menu > System >
> Muon PACKAGE  MANAGER >  check for updates. By doing so IN THIS STAGE, you
> will force the upgrade notifyer to appear.

> Finally, one more nasty detail in case you use Kompozer. This web authoring
>
> tool is obsolete and does not  work any more in 12.10 and beyond. However,
> there is a good alternative which is like Kompozer, but up to date:
> BlueGriffon.
> This package is not or not yet in a repository. Install it directly from
> BlueGriffon.org.
>
>>  Do I have to do a fresh install?
>
> What I usually do:
> 1. First upgrade.
> 2. Make a list of installed packages: see  http://bit.ly/OYQsls
> 3. Backup this list and all other files to an external HD, via the package
> "LuckyBackup".
> 4. Fresh install of the same Kubuntu version.
>
> I go through this four step cycle twice a year. Of course,  the backup I
> make
> more often; a few times per week.
> By doing so, I keep the system vital.
>
> I hope this helps.
