~/syscoin/src/syscoin-cli getinfo2) Or you can use this code created by Locutus
This will update your Manual Install setup, all in one line
cd $home && curl -sL https://raw.githubusercontent.com/locutus75/syscoinscripts/master/offlineupdatescript.sh --output $HOME/offlineupdatescript.sh && chmod u+x $HOME/offlineupdatescript.sh && ./offlineupdatescript.shThis is what it does:
- creates a ~/temp folder
- builds the latest syscoincore from github in this temp folder
- builds the latest sentinel from github
- copies current sentinel.conf
- stops syscoincore
- moves old ~/syscoin folder to ~/temp/syscoin-previous
- moves new ~/temp/syscoin to ~/syscoin
- starts syscoincore
This way, there is almost no downtime.
So you end up with a new version and also you have the old one backed up in ~/temp/syscoin-previous.
Check your version with
~/syscoin/src/syscoin-cli getinfoIf satisfied, you may remove your backup folder with this command
rm -rf ~/temp/syscoin-previous** Carry out Reload Blocks as above **
See below for QT Upgrade Instructions to 3.1.2.0
Close QT and download 3.1.2.0 from Github
ALWAYS ENSURE YOU HAVE A BACKUP OF WALLET.DAT
Go to your syscoincore folder
For WIN
C:\Users\YOURUSERNAME\AppData\Roaming\SyscoinCore
Or type %appdata% in the search box
For MAC
CMD + Shift + G
~/Library/Application Support/SyscoinCore
Remove any addnode connectnode lines from syscoin.conf
Delete the Blocks folder and peers.dat file
Open QT and it should start syncing within a minute or so.
If you still are not on the correct branch use this method.
1) Shut down QT.
2) Rename syscoincore folder to syscoincoreold.
3) Create a new syscoincore folder.
4) COPY wallet.dat and masternode.conf from syscoincoreold to the new folder.
5) Restart QT 3.1.2 or higher.
This gives you a new clean sync on the correct chain, and a backup. (sycoincoreold).
Any transactions that are “stuck” on the wrong chain will no longer be in mempool, will not have happened and your balance should be correct.
