This thing still appeared to not be working on the Unix version. But we tried compiling everything we've tried doing everything from point A to point B over and over again on completely Bare Bones systems completely new systems and nothing happens.

    MMGenLive has been upgraded to Bitcoin Core version 0.14.2 UASF-Segwit-BIP148. Users of the latest boot image can effect the upgrade by typing 'mmlive-upgrade'.  Use of the UASF client is optional.  To select it, run 'mmgen-node-start' with the '-U' switch.

Yes, provided you're storing your MMGen wallet or mnemonic in a safe location (preferably offline). But if you're using MMGen as a Bitcoin wallet, you'll be doing that anyway.

Is it safe to generate passwords with this tool?

The new 'mmgen-passgen' command allows you to generate and manage your online passwords with MMGen.

See the commit notes on Github for details.

MMGenLive has been upgraded to MMGen version 0.9.1. Users of the latest boot image (v0.0.7) may run 'mmlive-upgrade' to effect the upgrade.

Commit notes here: https://github.com/mmgen/mmgen/commit/93c99755a77606e5af7005a87fb40ae431992845

Basic documentation can also be found in the help screen for the new 'mmgen-txbump' command.

Version 0.9.1 will be released after documentation and testing of the new RBF and fee calculation functionality is complete.

MMGenLive has been upgraded to Bitcoin Core 0.14.0. Users of the latest boot image (v0.0.7) may run 'mmlive-upgrade' to effect the upgrade.

Announcing MMGenLive version 0.0.7

   This release of MMGenLive, the prebuilt bootable installation of the MMGen wallet system, has been updated with the latest versions of Ubuntu, Bitcoin Core and MMGen:
   

• Ubuntu 16.04 LTS 'xenial' (Intel 64-bit)
• Bitcoin Core v0.13.1
• MMGen v0.9.0

   The release introduces a new upgrade system. New features and bugfixes are now pushed to the repository in the form of revisions. To keep an online installation up to date with the latest revision, all that's required is to run the 'mmlive-upgrade' script from time to time. The upgrade process is automatic, requiring little or no user interaction.

Announcing MMGen version 0.8.9

This release brings full functionality and wider testing to the MS Windows port. MMGen now works with both WinXP/MinGW32 and Win7+/MinGW64, and separate, updated installation instructions for both platforms have been added to the wiki. A working MSYS/MinGW environment is now required to run MMGen under Windows.

    New Windows features:

• Full non-interactive test suite support with pexpect (PopenSpawn)
• secp256k1 address generation support
• Secure wallet deletion with sdelete

    Windows bugfixes:

• A critical bug in writing the encrypted keyaddrfile has been fixed. This bug would have affected only online wallet use and would not have led to the loss of coins
• Cookie filename fixed; RPC cookie authentication now functional

    General features:

• --bitcoin-data-dir, --rpc-port, --rpc-user, and --rpc-password options

Did you install xserver-xorg-video-vesa in the guest?

You should be booting right into an autologged-in X session, the screen you see in my writeup above.  If not, then something's wrong.

My host system is Ubuntu xenial, just like the boot image system:

The Mini-PC's been up and online for about a week now, almost 24/7, without so much as a hiccup. I'm very satisfied so far. I'd been considering something more minimal, too, but having some experience running full nodes it became clear that Pogoplugs, Raspberry PIs, etc. just aren't up to the task anymore. MMGen on a Pi makes a good offline signing machine, but not an online node.

What version of qemu are you using? I have QEMU emulator version 2.6.0 (Debian 1:2.6+dfsg-3.1) currently. I made need to build another from source as mine doesn't find the machine type.

Adding the -vga-std flag did allow me to type in user this time, but still hangs upon entering pass.

Not a big deal honestly, as I am used to working solely in cli. The minimalist in me will likely scrap the Lubuntu bits anyway and add mmgen to a gentoo image. 

The minipc thing is interesting as well. I was working with some guys on a pogoplug type box for this purpose though the insane memory requirements put a damper on it.

With qemu, install xserver-xorg-video-vesa and graphical boot will work!  You'll get best performance with -vga std.  These parameters work for me:
    
      qemu-system-x86_64 -vga std -m 1024 -enable-kvm -machine pc-q35-xenial,accel=kvm xenial64.img

The screen resolution is incorrect.  I'll see what I can do about that.

I've discovered that the ~/bin directory isn't always getting added to $PATH. So you have to do it by hand, or run the scripts as bin/.

These issues will be fixed by the next release.

It allows me to decrypt fs, but when it gets to user login it just sort of "loops" there and allows no input. If I get a chance this week I will see if I can dump some debug information on it.

The other method works fine however, so if there are users accustomed to command line that want to give it a test drive, it's an option.

Glad to hear it! I've tested it on a variety of hardware but never tried booting it in a virtual machine. At what stage did the graphics boot fail?

Hi managed to get it running inside qemu, though the graphical version didn't work. (Cli is all I need anyway) I probably need to tweak a few settings to optimize it. I look forward to digging in more.
