We know that do-release-upgrade “does a release upgrade”. But at a little lower level what does it really do?  I plan to do a more manual upgrade, for instance the Debian way: aptitude update and aptitude full-upgrade after setting up the sources. Actually, I plan to do it entirely interactive with aptitude. But that leaves me curious about what else do-relase-upgrade does, except hosing up my sources.list.

I had to remove Chrome to have enough space to upgrade from 16.10 to 17.04.  I downloaded the latest version from Google.  But when it opens in the Ubuntu Software Manager, and I click on "Install", nothing happens.

I have a server running 12.04.4 32 bits Ubuntu server, and I wonder if there could be any unsolvable problem updating to 14.04.1 as the terminal suggest me (using do-release-upgrade) to do.

I haven't seen this message from Update Manager before, and I have not been able to google up any info.  What will be installed when I click Install?  (Clicking "Description of Update" got me nothing...)

Just as the question says, I need to install newer version of Ubuntu without messing up the older version. I have looked at the responses to similar questions but it isn't clear to me how to do so (some suggest dual boot using a second hdd and some suggest using virtualization -- both of these are not an option for me).

What would be your advice?  UPDATE: I already updated the system to 19.10. Thank you very much for the advices.

I had several friends ask me to update their Ubuntu to a newer kernel without changing the version of Ubuntu. So for example, staying in 10.04 with the 3.3 Kernel version.  When having an older or present Ubuntu version, many users want to apply the newer stable/unstable kernel version to the Ubuntu version they are using thinking that it is similar to upgrading a program. So what I am looking for, are some simple answers to explain the dangers (that are pretty much bigger than the advantages) of forcing a newer kernel version in a Ubuntu release that was not meant for it.  What can I tell them or explain to them of why they should NOT update to a newer/older kernel when having an Ubuntu version that was not made for that kernel version.
