Man, I've now learnt to check MD5sums of all ISOs I download from now on, it
had a different MD5! Now downloading the ISO from a direct link based on the
MD5 url you gave (so
http://cdimage.trisquel.info/trisquel-images/trisquel_7.0_amd64.iso),
on my - you guessed it - fairly slow VPN... :)
Thank you! I think that was obviously it, data corruption of some kind.
Indeed I DID have an Internet disruption during the download now that I
remember it, and a dl resume across an entire reboot and everything. Maybe
not the best idea in Firefox, that! And actually, I probably will remember to
TORRENT as many ISOs as I can too, now...may take longer to download if not
the most popular ISO but worth the wait since you're guaranteed to not have
to re-dl it at least.
That's an excellent idea about VPN'ing the Internet ON the Live OS and
launching the installer on its Desktop there, though - indeed, not
complicated. (But clearly I need to re-download the ISO in case of other
issues anyway.)
However, wouldn't there be some 'restart' at some point in the install
process and thus possible downloading of packages/connecting to random
servers which after restart from the live OS obviously means your real IP is
involved?
That's the issue facing that idea (which is still, good to know about) - it
may not be 100% robust - I mean you can probably unplug Ethernet once the
'now rebooting' part happens, but.... I still want to keep Ethernet unplugged
until the first thing I do is connect to my VPN in the installed OS, all
controlled by me, no unpredictable surprises. This is pretty important for
someone serious about their anonymity/privacy, where they don't intend to
make mistakes if they can help it.
o, I'll try a correct ISO offline install, and if nothing goes wrong I won't
reply (about it if I have nothing else to reply about), and you can assume
the offline install went as well as the test Ubuntu one I just did, which
yes, worked without a hitch.
Thanks again :).
