Importing wallet balances from MUE 1.0.3 wallets into MUE 2.0 wallets

MUE has migrated to a completely new codebase, and as such, is no longer compatible with the previous network and blockchain used by the old 1.0.3 wallets. As part of the migration to the MUE 2.0 wallets and network, users can redeem their old wallet balances* into their new wallets. This process is simple, but if not done correctly could risk you losing all your coins.

NEVER UNDER ANY CIRCUMSTANCES GIVE AWAY YOUR PRIVATE KEYS TO ANYONE, THE ONE WHO HAS YOUR KEYS CONTROLS YOUR MUE

Please follow these simple steps

1. BACKUP your old MUE wallet, make multiple copies (most critical is your wallet.dat file!)
2. Copy that back up somewhere safe e.g USB drive, seperate computer.
3. Make a list of your wallet addresses (you may need to look in "coin control" for a full list). If coin control is not available in the send tab of your wallet, then activate this under śettings / Options / Wallet / Enable Coin Control Features
4. For each wallet address (that you know has a balance of MUE) in debug console run dumpprivkey 7enteryourmuewalletaddresshere
5. Record the private key (securely & safely) that is printed there
6. As per item 2) Backup your old MUE wallet (just to be sure). Again, critical is your wallet.dat file
7. Uninstall your old MUE wallet IF you are installing the 2.0 wallet on the same machine (to avoid any conflicts). For the sake of safety, you may also rename your MUE folder to say MUE-1.0.3-backup so it is preserved on your machine if things go wrong.
8. Install the new MUE 2.0 wallet
9. In debug console run importprivkey KenterYourPrivateKeyHere "comment"

You should now see your old MUE balance re-instated into the new MUE 2.0 wallet. For security, we strongly recommend you now send those coins to yourself to a newly generated receive address created in your own 2.0 wallet.

How to run the linux monetaryunit-qt executable under Windows Subsystem Linux

Please follow these steps

1. (Windows) Install VcXsrv
2. (Windows) Run XLaunch
   1. Display settings: Keep default settings (Multible Windows + Display number = -1)
   2. Client startup: Keep default settings (Start no client)
   3. Extra settings: Enable all checkboxes especially "Disable access control" or it will not work.
   4. (Optional) Save the settings for later use.
3. (WSL) Add export DISPLAY=$(grep -m 1 nameserver /etc/resolv.conf | awk '{print $2}'):0.0 to the end of your .bashrc
4. (WSL) Start monetaryunit-qt
5. (Optional) In case this did not work. Most likeley your windows firewall is blocking the connection. During the first start of XLaunch some rules will be set. Search for the blocking firewall rules "VcXsrv windows xserver" and disable them.

The partner instant exchange SimpleSwap.io

Hi,

I am Nicolas, the manager at SimpleSwap.io, an instant cryptocurrency exchange.

We present a simple and easy-to-use platform that works without registration and limits and allows users to make swaps in just two clicks.

We successfully support MUE on our service for a long time and we have been exchanging MUE for more than 200 coins to our customers. I tried to find contact with your team but without results.

I'm sorry that I invaded here, but maybe you can tell me where I can turn. I would like to make contact so we can have an interaction.

2.1.1 Pre-Release on RPI fails to sync blockchain

Describe the issue

Can you reliably reproduce the issue?

If so, please list the steps to reproduce below:

1. Install the 2.1.1 daemon and qt-client on a r-pi/raspbian system
2. Run the MUE QT-wallet
3. Chain gets stuck on block #140905. After closing the wallet, any attempt to use -reindex, -rescan or simply restart the wallet gives a seg fault.

Expected behavior

Tell us what should happen

1. The 2.1.1 wallet gets stuck on block 140905, while the 2.0.2 wallet does not.

Actual behavior

Tell us what happens instead

Screenshots.

What version of MonetaryUnit Core are you using?

https://github.com/muecoin/MUE/releases/download/v2.1.1/mon-2.1.1-arm-linux-gnueabihf.tar.gz

Machine specs:

• OS: Raspbian Stretch with desktop / Image with desktop based on Debian Stretch / Version:November 2018 / Release date:2018-11-13 / Kernel version:4.14
• CPU: ARM
• RAM: 1GB
• Disk size: 16GB
• Disk Type (HD/SDD): SD card

Any extra information that might be useful in the debugging process.

After crashing / seg fault, removal of the blockchain and chainstate data allows the QT wallet to start again, and re-download the blockchain again, and then again get stuck on block #140905.

Wallet v2.0.2 crashes on startup after MacOS Mojave 10.14 upgrade

After upgrading MacOS 10.13 (High Sierra) to 10.14 (Mojave) the wallet stopped working. It crashes directly after starting up. Occasionally it doesn't crash but instead freezes on loading, showing only the orange splash screen with the logo.
