This is not a duplicate because this has not been answered.

Because 14.10 no longer exists, I am unable to upgrade to 15.10. The reason why I would like to upgrade is because 14.04LTS is very slow and not stable on my hardware. I have installed 15.10 on a different PC and it works great. Plus a live CD of 15.10 runs well on the PC I am having issues with.

Is there a way to manually upgrade using a live CD of 14.10 and has anyone tried this?

When I try to update using terminal this is what happens: LINK

  • What is your reason for not doing a clean install of 15.10 (after backing up your personal files & data)? – DK Bose Jan 16 '16 at 15:41
  • If I cannot upgrade using a live CD, I may do a clean install. I have a lot of data to back up and it takes a long time to do so. I wondered if anyone ever upgraded using a live CD to 14.10, then it should be possible to upgrade in the usual way after that. – pst007x Jan 17 '16 at 00:22

Even if there is way to do a manual upgrade, if you don't know what exactly are you tweaking, you will end up with a broken system, which happens quite often.

I would recommend you to use your 14.04 for a bit longer, I myself use 14.04 and I only use LTS versions, packages are more stable and more relevant tutorials that way.

14.04 has 5 years of support, 16.04 will come out this year. So, wait a bit, and upgrade from 14.04 LTS to 16.04 LTS which is possible.

  • I wondered if anyone has upgraded using a live CD. If so, I could upgrade to 14.10 first using the live CD, then upgrade normally afterwards. I wanted to upgrade because my PC is unstable using 14.04LTS, constant crashes, etc. I have proven out hardware. Worst case I'll have to wait rather than breaking my system.

  • thats why i always have a clonezilla backup of the partition,then if something goes wrong which certainly will i can go back to the way things were,like some days back even uninstalling wine showed that some packages are orphaned so i did apt-get autoremove and that remove dependencies of the desktop environments even cinnamon and gnome was not working – Shantanu Bedajna Jan 17 '16 at 07:41
