Upgrade 'challenge' for Xubuntu 14.04

Hi all,
I have a 'challenge' in Xubuntu... I have a home server running on Xubuntu 14.04 and installed LAMP like described in the article 'The Perfect Server' here on HowtoForge. I also installed 'ownCload' as a personal cload server.

Now I'm facing the fact that my sytem feezes after some time being idle. I had an extensive search on the interweb to find a solution, tried probably all of them (incl. nVidia driver changing, lightdm service stoped etc.), but nothing seems to work. As a final solution I want to try is to upgrade the system to Xubuntu 15.10 and see if that bug has been solved...

However... if I try an upgrade I get an error message that says: 'There is an unsolvable problem detected'
The causes is probably that I have unofficial software packages not being provided by Ubuntu (like ISPConfig 3 and ownCload).

Now, is there a way to upgrade without having to reïnstall every thing I have so painfully configured?
I'm kind of a newbie to Linux, all my 'knowledge' comes from those great tutorials I find all over the interweb...

Hiya,

Are you trying to update from 14.04 to 15.10 immediately or in steps? Because the updating process will fail if you don't do it in steps. So please try the following:
14.04 --> 14.10
14.10 --> 15.04
15.04 --> 15.10
This should work if you got a properly working net connection for downloading.

 

Hello CrypticDesigns,
Yes, that was my initial approach because I have read about this before. However 14.10 is EOL, so I can't upgrade from 14.04 to 14.10 the 'normal' way I know, because using the update tool I can't select that option.
So if you know I way I can do it without the update tool, please advice me...
As said before, I'm quite a newbie....

 

Im not really experience with XUbuntu but try this:
Open a terminal and run:

Code:

sudo -i
apt-get update
apt-get dist-upgrade

Reboot your system to finish installing updates, and to upgrade to new available version:

Run:

Code:

sudo -i
update-manager -d

Software Updater will show up and search for the new release, after a few seconds, you will see a screen like below that saying:

However, Ubuntu 14.10 is available now (you have 14.04).

Press the button Upgrade to start upgrading to Ubuntu 14.10.



The Software Updater will ask you to confirm still you want to upgrade, press Start Upgrade to begin installing Ubuntu 14.10.

Now, the Software Updater will prepare to start setting up new software channels, and after a few minutes, the software updater will notify you the details the number of packages are going to be removed, and number of packages are going to be installed, press Start upgrade to continue.

Ended the dist-upgrade, reboot your system and:

Run:

Code:

sudo -i
dpkg --configure -a
apt-get -f install
apt-get update
apt-get dist-upgrade
apt-get autoremove
apt-get clean

Hope this will help you
