I am currently running Ubuntu Gnome 15.04, with Gnome Shell, and Gnome 3.14, but I am thinking about upgrading Gnome from 3.14 to 3.16 using these PPAs:

  • gnome3-team/gnome3-staging
  • gnome3-team/gnome3

But then when I want to upgrade to Ubuntu Gnome 15.10, if say it is still running Gnome 3.14, or a higher version, could this lead to what is known as 'dependency hell'?

  • It is can be more stable to do a fresh install anyway (easy with a separate /home). Anyway, if you are not sure, you can uninstall the PPA's packages (using ppa-purge, selecting it in Synaptic etc) and then upgrade - it should be fine then. – Wilf Aug 06 '15 at 12:43

If you are not sure the upgrade will go to plan with the upgrade, you can uninstall the PPA's packages:

  • Using ppa-purge, selecting it in Synaptic etc) and then upgrade - it should be fine then.)

  • Using Synaptic may work on difficult PPAs, as I found out here:

    ppa-purge is ineffectual with that ppa, (elementary-os/daily) & probably the same with autoremove. I'd add back the ppa & update sources. Then open synaptic > Origin. Click on the entry for that ppa/now. With shift+click highlight all the packages & mark for removal, ect. Then get rid of the ppa.

It may be more stable to do a fresh install anyway (and this is very easy with a separate /home, the installer may automatically offer to do it for you). It may be more stable to do a fresh install anyway (and this is very easy with a separate /home, the installer may automatically offer to do it for you)) - This has been discussed here. You may be able to do a fresh install after a botched upgrade as well.

Just make sure when you do upgrade you have a reliable backup of everything (or just what data is important) so if it does go wrong you can restore easily.
