I think this is wise. In case you haven't heard the rumblings about
ubuntu-release and ubuntu-devel, there's much talk of dropping 32 bit.
In fact, most flavors have opted to drop it. Lubuntu is seriously
considering following suit.
Do note, though, that despite the potential for dropping it as a release
architecture, 32 bit packages will likely live on for a long time.
My idea is to restore (including hidden files) my 32-bit Lubuntu 16.04.4
/home directory, to a new Lubuntu 18.04 64-bit system.
I think this is the best solution, though I have not tested it. I had a
multiarch system set up, where I was running a 64 bit kernel but had a
menagerie of 32 and 64 bit userland that had all sorts of dependency
issues. I probably could have bothered to ultimately fix it, but it
would have been much more headache than what I wanted. Ultimately, I
gave up on it and installed a new system. I actually restored only the
/home files (especially configs) that I needed, after the new system was
installed. The advantage of this is that if something about the format
or options of the config files changed in the upgrade, I wasn't stuck
trying to figure that out.
Let us know how it goes!
Walter:
Thank you very much for commenting on my proposed change, based on your
extensive experience.
A hard-drive that is on its 'last-legs' is driving me to change now.
I think what I'm going to do, since I still need to support both 32-bit
and 64-bit asound library Java-native code, is that I will start with
restoring to a 32-bit system on the new drive, then try what I mentioned
above, restoring to a 64-bit system.
At some point, when I am satisfied with the 64-bit system, I will
'transfer my flag' to the 64-bit system.
I'm assuming that since Lubuntu 18.04 is a Long Term Support system, and
that it now supports 32-bit architecture, that it will continue to
support 32-bit architecture through its support life.
