I have denarius snap already installed so I add denarius_1 as above and this is what snap list shows.

Running non stock kernels in Ubuntu, you might get an SELINUX error like "cmd_run.go:876: WARNING: cannot create user data directory: failed to verify SELinux context"

sudo apt install selinux-policy-default
sudo nano /etc/selinux/config

then change the config file to SELINUX=disabled

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled

reboot system

thanks a lot for this awesome guide. i didn't know snap rocks that much

[chris92]

If you get this error:

Command 'denarius.daemon' is available in '/snap/bin/denarius.daemon'
The command could not be located because '/snap/bin' is not included in the PATH environment variable.

... when starting the daemon via "denarius.daemon", you need to do the following:

1) Folder "etc" => open file "environment"

2) Add "/snap/bin:" to the string, for me it looks like this: "PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:""

3) "reboot" to restart VPS

=> "denarius.daemon" should work

To install Denarius snap QT / daemon in Qubes OS.

reference: https://www.qubes-os.org/doc/software-update-domu/ "Installing Snap Packages"

Open up one of the template VM terminals like Fedora Template VM.

sudo dnf install snapd qubes-snapd-helper

Then shutdown the TemplateVM.

sudo shutdown -h now

Once this is done, create a new AppVM based on that TemplateVM.

I used these settings.

Name and Label: Crypto
Color: Purple
Type: Qube based on a template (AppVM)
Template: default (fedora-30)
Networking: sys-whonix
launch settings after creation

Then gave it 12gb of storage in the settings. Start a terminal in the new AppVM.

snap install denarius

After that's done go back to your Qube Settings -> Applications -> Click Refresh Applications, click Denarius then the single arrow to move it so selected, click OK.

You can run Denarius Snap QT from the menu, or go to terminal and run denarius.daemon for the daemon. A nice feature is that you can run under whatever firewall rules you want. In this example using sys-whonix I am now through TOR completely.

To mount the chaindata folder to another location, like external drive. Install snap in devmode, this will not auto update the Denarius snap though.

snap install --devmode denarius

reference: https://forum.proxmox.com/threads/ubuntu-snaps-inside-lxc-container-on-proxmox.36463/post-230060

To run snap denarius daemon in an proxmox lxc unprivileged container go to your container -> Options -> Features and checkmark Nesting & FUSE

sudo apt update
sudo apt install snapd
sudo snap install denarius

You will get an error on the first snap install denarius, run snap install denarius a 2nd time and it will install.

sudo snap install denarius

Yes just wanted to say snapd relies on FUSE typically, it is installed within this tutorial I did as well:

That could relate in ways to this

[buzzkillb]

To run mainnet and testnet daemons together.

sudo snap set system experimental.parallel-instances=true
sudo snap install denarius
sudo snap install denarius denarius_1
denarius.daemon
denarius_1.daemon -testnet

Folders where the chaindata is located by default. denarius.conf and fortunastake.conf always in .denarius folder

~/snap/denarius/common/.denarius
~/snap/denarius_1/common/.denarius/testnet

You may need to edit rpcport and port in for the testnet daemon. rpcport=32368 and port=33368. Testnet fortunastake port is 19999.

I think the Parallel instance feature of Snapcraft is highly under-rated....It is an amazing feature of Snap and allows one to run multiple instances of Denarius on the same machine including a mix of testnet/mainnet nodes.
