Edit : Note that it is not yet possible to migrate from 16.04.05 LTS to 18.04.1 LTS. Today is Tuesday, August 7.... The release of 18.04.1 LTS took place on July 26... They must have simply forgotten to enable the "For long-term support versions" option in "Notify me of a new Ubuntu version", in the "Software Updater" options... Someone absolutely must tell them please.

This documentation https://help.ubuntu.com/community/BionicUpgrades indicates, in the part titled "Upgrade from 16.04 or 17.10 to 18.04 > Upgrading Ubuntu Desktops to 18.04 (Recommended)" that in order to migrate from 16.04 (16.04.5 LTS for me) to 18.04 (18.04.1 LTS in fact), we must confirm the "Notify me of a new Ubuntu version:" option is set to "For any new version", and change it if otherwise.

My question is : why not to keep it set at its default value, which is : "For long-term support versions" ? 18.04(.1) is indeed an LTS version ! So this option should also enable the migration.

I have another question: in addition to allowing the change from 16.04(.5) to 18.04(.1), what are/will be the other (potentially bad) consequences of choosing the "For any new version" option, recommended by the above documentation?

Am I making a mistake ?

Important

This migration is really impossible when "For long term support versions" is chosen. It's possible when "For any new version" is chosen.

Maybe I wasn’t rigorous enough in reading the page, but I can’t edit the Ubuntu Wiki Official Documentation.

I logged in using my UbuntuOne Account and using my Launchpad Account but still I can’t edit the page.

Let us take an example on this page: https://help.ubuntu.com/community/MpichCluster

I found an error in the keychain set code instruction on MPICH Cluster arrangement. The instruction asks us to put some code in the ~/.bashrc file. It was written as:

if type keychain >/dev/null 2>/dev/null; then
  keychain --nogui -q id_rsa
  [ -f ~/.keychain/${HOSTNAME}-sh ] && . ~/.keychain/${HOSTNAME}-sh
  [ -f ~/.keychain/${HOSTNAME}-sh-gpg ] && . ~/.keychain/${HOSTNAME}-sh-gpg

We should add fi to complete this code. Otherwise it will give us error. I want to add that fix. I also want to add a comment that this action should be done in the master machine, not in the helper machine (I prefer to use “helper machine” instead of “slave machine”).

Maybe somebody can help to do this. Thank you

I realised I'm a bit confused about something. I have found three separate wikis hosted at ubuntu.com, and I'd like to know their respective purposes and relationships. I have some guesses (see below) but I'd prefer some clear/official/de facto descriptions or links.

Official Documentation (https://help.ubuntu.com) My guess: the official wiki page for running X on Ubuntu, where X is an officially supported package.

Community Help Wiki (https://help.ubuntu.com/community) My guess: the public wiki page for running X on Ubuntu, where X is any old thing.

Ubuntu Wiki (https://wiki.ubuntu.com) My guess: contributor-supported documentation for how to make contributions to the Ubuntu platform itself (not development for Ubuntu).

My primary interest here is in understand what they are so I can a) use them for my own reference, b) contribute to them if possible and c) link to them from AU (where relevant)
