    Downloaded a frsh copy of LM18.3 Cinnamon...from Linuxmint.com
    stuck the download in a folder in 'Home" called ISO
    Ran the terminal commands to generate the hash....compared below



    ecebdf9ac4697b6c2d7feffd1bc5430641bca67c7df122fa2914824dc8844b3a ....(sha256sum.txt)

    generated by terminal
    cd
    cd ISO
    sha256sum -b *.iso
    371f3bbed239ade323ef8b6c5d9b80eead594c2a15913888f5ed9972df09e7e4

    This actually makes sense....because the bootable usb I made will boot....but the result is a Linux desktop with no panel and no icons at all

    In fact I have dual monitors, and after installing a panel and a 'menu' applet....open menu, type FIREFOX, and then right click to put an icon on the desktop and on the taskbar ....zero....nothing.

    This is the second time I have downloaded 18.3 from The official place....via torrent.



    I also this afternoon downloaded LM 19 cinnamon from the same place, again via torrent.

    Result...perfect.

    Why ?

    What to do ?

    That's strange - could be that the torrent download didn't grab the entire file. OR, it could mean that someone has messed with the LM iso - it happened a cpl years ago.

    I'll give it a shot also.

    The same thing happened with a download of 18.3 I made a few weeks ago.......it booted but had no panel no icons etc etc.......I wasnt too fussed at the time, so I just dumped it.

    I did not check the iso

    I think you got a bad / incomplete torrent. I just grabbed 18.3 via torrent and things match up:

    Code:
    [email protected]:~/ISO$ cat sha256sum.txt|grep cinnamon-64
    ecebdf9ac4697b6c2d7feffd1bc5430641bca67c7df122fa2914824dc8844b3a *linuxmint-18.3-cinnamon-64bit.iso
    [email protected]:~/ISO$ sha256sum -b *.iso
    ecebdf9ac4697b6c2d7feffd1bc5430641bca67c7df122fa2914824dc8844b3a *linuxmint-18.3-cinnamon-64bit.iso
    
    While verifying the key i get:
    Code:
    [email protected]:~/ISO$ gpg --verify sha256sum.txt.gpg sha256sum.txt
    gpg: Signature made Wed 13 Dec 2017 11:16:15 AM EST using RSA key ID A25BAE09

    Ok....back to the drawing board......actually the land of slowwww downloads. My current position on the globe leaves much to be desired.

    i will try again and drop the results here.

    Thanks for looking in.

    Success.

    I right clicked on the download and selected "Check SHA256"....and that worked nicely. matched perfectly.

    Bad torrents....both of them....probably interrupted because of screwy signal in this god forsaken country.

    lesson learned.

    Thanks Rob

    I am lost. I wrote the iso to my usb....unetbootin the first time and then used right click on the iso and select make bootable usb stick the second time

    (I had already formatted the usb to fat 32, both times)

    Booted

    Shows no panel and no icons

    Using the same usb stick as used with LM 19.....which worked perfectly.

    Is it the standard issue of Unetbootin from the Repositories, or an upgraded one added through PPA?

    Tried Etcher or Multisystem?

    Cheers

    I downloaded yet another iso from linuxmint.com

    After some serious screwing around.....I discovered that if I right clicked the desktop and selected 'desktop Settings'....then chose to 'show icons on no primary monitors only'.....a small group of icons came up on the left hand monitor(which I usually regard as the non primary monitor)

    The icons are :: computer....install LM.....Multisystem.....and 'Home'

    I stayed in settings and then chose display......I set the right hand monitor as 'primary', and clicked 'apply'........which did two things.

    It put in place a 'panel' (task bar" on the primary monitor, and moved the icons to the primary monitor as well.

    Weirdness. All the while I was doing this....I was strongly reminded of my previous attempts to get 18.3 running in live mode. Too many similarities to be a coincidence. (And I dont believe in coincidences.)
    It is as if there is a 'memory' somewhere that newly downloaded iso's and multiple formats does not erase. Whatever...it works....enough of the woo woo crap !

    I ended up using Multisystem. .... does the job really quickly.....once you have figured it out. I added 4gb of persistence after the fact. Do i remember you saying you had figured how to use more than 4gb, Wiz....do tell !

    This all goes to show that The download via torrent etc was not the problem.

    Yeah ok....I'll go and drink more scotch....that'll help.
