Hey guys,
I was pretty excited about 10.04 and new social networking support. I wanted to get it as soon as possible but alas I couldn't here is an error which I received:
An unresolvable problem occurred while calculating the upgrade:
E:Unable to correct problems, you have held broken packages.
This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu
If none of this applies, then please report this bug against the
'update-manager' package and include the files in
/var/log/dist-upgrade/ in the bug report.
Restoring original system state
Looking around a little I came to know its an issue with third party softwares.
So there was option of clean upgrade where I was supposed to remove all third party softwares which included edgers driver for x server (if you have followed previous post about installing drivers for 3D games) and in term UI and all. Which is really scary :s.
Luckily I found a roundabout way to do it, Here are steps:
Deactivate all third party repositories:
- System --> Administration --> Software Sources --> Other Software
Untick all repositories --> Close.
If you have already executed update to new distribution:
cd to /var/log/dist-update then cd to latest directory (for each upgraded try there will be a directory created with date as its name)
- cat main.log
Around the end of this file - main.log you will see conflicting repository (mostly xorg repository)
Look for packages related to this repository in synaptic
- Select package --> Package (tab) --> Force Version and force it to downgrade to package available in Ubuntu repository
Now you are set to go retry upgrade and it should work without any issue at all :)
Have fun hope that works for you as well.
