     Aborted (core dumped)

     or
     

      A fatal error occurred. Dash Core can no longer continue safely and will quit

   • This is caused by a conflict in theme names between v0.14 and v0.16, it's possible people who ran v0.14 might crash when launching v0.16. To fix it, open a command prompt / terminal and run:
     linux:
     

     dash-qt -resetguisettings

     windows:
     if installed in default location:
     

      "C:\Program Files\DashCore\dash-qt.exe" -resetguisettings

     Navigate to folder where Dash-qt.exe is located and run
     

     dash-qt.exe -resetguisettings

     Mac:
     

     /Applications/Dash-Qt.app/Contents/MacOS/Dash-Qt -resetguisettings

2. "Sentinel fails with an error"
   • Error
     

     [email protected]:~/.dashcore/sentinel$ venv/bin/python bin/sentinel.py
     Traceback (most recent call last):
     File "bin/sentinel.py", line 223, in <module>
     main()
     File "bin/sentinel.py", line 129, in main
     if not dashd.is_synced():
     File "lib/dashd.py", line 98, in is_synced
     synced = (mnsync_status['IsSynced'] and not mnsync_status['IsFailed'])
     KeyError: 'IsFailed'

   • This issue has been solved in the latest version of sentinel
     

     cd sentinel
     git pull
     python3 bin/sentinel.py --version

     Make sure it says v1.5.0 (or maybe greater but this is the newest at time of writing)

For masternodes installed using the instructions in the docs, the commands are:

cd ~/.dashcore/sentinel
git pull
venv/bin/python bin/sentinel.py --version
venv/bin/python bin/sentinel.py

Hi,
I tried to update using dashman, using

~/dashman/dashman sync update -y

but got a POSE BANNED error on the DashMasternodeTool.

Then when I run

~/dashman/dashman status

I get:

dashd version : 0.16.0.1
dashd up-to-date : YES
dashd running : YES
dashd uptime : 0 days, 0 hours, 0 mins, 0 secs
dashd responding (rpc) : NO
dashd listening (ip) : NO
dashd connecting (peers) : NO
dashd port open : NO
dashd connection count : 0
dashd blocks synced : NO
last block (local dashd) : 0
(chainz) : 1351176
(dash.org) : 0
(dashwhale) : 1351177
(masternode.me) : 1351177 - no forks detected
dashd current difficulty :
masternode count : 0

What went wrong?

Many thanks.

So one problem was that

-maxconnections was set to 64.

I changed that by changing the dashd.conf and setting it to 128.

I am still getting a warning:

Warning: -masternode option is deprecated and ignored, specifying -masternodeblsprivkey is enough to start this node as a masternode.

But I do not know what to change for this.

Also now when I started dashd I got:


masternode mnsync state : /home/xxx/dashman/lib/dashman_functions.sh: line 1238: : command not found

But now that has disappeared:

masternode mnsync state : MASTERNODE_SYNC_GOVERNANCE

On the other hand it is still POSE BANNED. How do I unban it?

Thanks.

Maintenance — Dash latest documentation

Maintaining a Dash masternode involves staying up to date with the latest version, voting and handling payments

Thanks.

To make this very simple for anyone reading this (or myself in future).
After you have cleared whatever was cousing the POSE then go to the Dash Masternode Tool and press the Update Service button. And then Send Update Transaction. And then wait.

Yes, I had exactly the same problem. Solved it by manually adjusting the max connections to a 125 ... by editing the dashd.conf in the .dashcore folder.

I went up almost immediately in my (negative) POSE score to over 3.000 within about 2 hours... and now that it's working again keep coming down...

I get the same error messages you mentioned in red, but they dont seem to have an effect... I think they are die to the fact that dashman isnt really being updated any more... which is sad...

Please note, dashman is NOT supported and you should be investigating moving to other tools

 

[qwizzie]

The remaining warning message in red when starting dashd has nothing to do with dashman no longer being supported. I have not been using dashman and i get that red warning too. I think the warning is there to inform users that the masternode through BLS is registered directly on the blockchain and no longer depends on .. something (i forgot the specifics of this warning).

I think the red warning message is related to either something in the dash.conf that got obsolete (maybe the masternode priv key presence triggers that warning ?) or it is related to the masternode.conf itself. Either way, you can indeed ignore it. But it would be nice if we know how to avoid triggering that warning message.

Thank you. I didn't know that. I will keep moving away from it over the next 12 months. It seems to work ever less anyway...

Does not work:
```
/dash-qt -resetguisettings
std::terminate() called due to unhandled exception
Exception: type=std::runtime_error, what="operator(): Failed to open file: :css/light"
No debug information available for stacktrace. You should add debug information and then run:
dash-qt -printcrashinfo=bvcgc43iinzgc43ijfxgm3ybaadwiyltnawxc5ejo
```

the crash happens before it even parsed.
no way to run dash-qt.
