[Mint] Installing Manjaro KDE Plasma in VirtualBox 6.0 on Linux Mint 19.2 Cinnamon

 , , , ,

Install VirtualBox 6.0 on Linux Mint.

wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -
echo "deb [arch=amd64] https://download.virtualbox.org/virtualbox/debian bionic contrib" | sudo tee /etc/apt/sources.list.d/virtualbox.list
sudo apt-get update
sudo apt-get install -y virtualbox-6.0

Download the Manjaro ISO here.
Run VirtualBox and create a new VM with type “Linux” and version “Arch Linux (64-bit)”. If done, go to Settings -> Display and switch Graphics Controller to “VBoxVGA” to be able to change the screen resolution of your VM. For transparency effects, you can also check “Enable 3D Acceleration”.
(Changing this setting didn’t work on my existing VM, only when creating a new VM. So it’s important to do this step before installing the OS.)

Now go to Storage and add your Manjaro ISO as optical drive.

Start the VM and go through the Manjaro installation process. If done, shutdown your VM, go back to settings and remove the Manjaro ISO as optical drive. Else it will boot again into the installer. Now start the VM again.

To run with the VirtualBox Guest Additions, you only have to install virtual-box-utils inside your VM:

sudo pacman -S virtualbox-guest-utils

[Mint] Installing KDE Plasma Desktop on Linux Mint 19.2 Cinnamon

 , , 
sudo add-apt-repository ppa:kubuntu-ppa/backports
sudo apt upgrade
sudo aptitude install --with-recommends kubuntu-desktop

Without the “recommends” you’ll get some errors about missing dependencies like here:

The following packages have unmet dependencies:  kubuntu-desktop : Depends: software-properties-kde but it is not going to be installed

Because Linux Mint 19.2 is based on Ubuntu 18.04., the Kubuntu backports only provides Plasma Version 5.12.19.
Ubuntu 18.04 contains Qt Version 5.9.5 and Plasma 5.13 will need at least Qt 5.10.
You can check the current Qt and Plasma version with

[Mint] Install Bitwarden-CLI on Linux Mint 19.2 Cinnamon

 , ,

Find their Github here and their Documentation here. They recommend to install via NPM. So first we have to install the Node.js runtime if you have not yet.
If you follow the Node.js installation guide you would use:

sudo apt-get install curl python-software-properties
curl -sL https://deb.nodesource.com/setup_12.x | sudo bash -

But this will lead into the following, since 19.2 Tina is not yet support (on 19.1 Tara it will run fine).

## Confirming "tina" is supported...

+ curl -sLf -o /dev/null 'https://deb.nodesource.com/node_12.x/dists/tina/Release'

## Your distribution, identified as "tina", is not currently supported, please contact NodeSource at https://github.com/nodesource/distributions/issues if you think this is incorrect or would like your distribution to be considered for support

So we have to do it manually. I used this little how-to i found on Github:

# Add missing signature
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key 1655A0AB68576280

# Replace misconfigured  sources file. Change version of node you like to have. 8/10/12
echo -e "deb https://deb.nodesource.com/node_10.x bionic main" | sudo tee /etc/apt/sources.list.d/nodesource.list
echo -e "deb-src https://deb.nodesource.com/node_10.x bionic main" | sudo tee -a /etc/apt/sources.list.d/nodesource.list

# Update packages and install
sudo apt update
sudo apt install nodejs

Finally install Bitwarden-CLI with a single line.

sudo npm install -g @bitwarden/cli

Now you can login into Bitwarden. If you have enabled any two-step login method, you have to add the parameter “–method” and a specific value for the login in method you can find here. In my case “0”, as I’m using TOTP.

bw login --method 0

If you successfully logged in, you will get your session key and are able to read your passwords:

To unlock your vault, set your session key to the `BW_SESSION` environment variable. ex:
$ export BW_SESSION="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
> $env:BW_SESSION="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
You can also pass the session key to any command with the `--session` option. ex:
$ bw list items --session xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Nextcloud

[Nextcloud] Restrict access to your ONLYOFFICE Document Service to the users of your Nextcloud instance

 , ,

Enable JWT token

Add a Token in you local.json file. If your running ONLYOFFICE on linux you will find the file here:

/etc/onlyoffice/documentserver/local.json

Set inbox, outbox and browser to true and add you token in the secret part for inbox, outbox and session. I just generated a random string via Bitwarden.

   "token": {
        "enable": {
          "request": {
            "inbox": true,
            "outbox": true
          },
          "browser": true
        },
        "inbox": {
          "header": "Authorization"
        },
        "outbox": {
          "header": "Authorization"
        }
      },
      "secret": {
        "inbox": {
          "string": "token_string"
        },
        "outbox": {
          "string": "token_string"
        },
        "session": {
          "string": "token_string"
        }

Save the file and run:

supervisorctl restart all

Go to your Nextcloud web interface, open your ONLYOFFICE App and add your token beneath your server url.

Configure IP Filter

Search in the following file for “ipfilter”:

/etc/onlyoffice/documentserver/default.json

Add you domain or IP to the IP rules. Disallow everything else. Use * as wildcard. Also set useforrequest to true.

"ipfilter": {
              "rules": [{"address": "url_or_ip", "allowed": true},
                        {"address": "*",         "allowed": false}],
              "useforrequest": true,
              "errorcode": 403
            },

Now run again:

supervisorctl restart all

And test if the service is reachable.

[Jellyfin] Deleting files on a mounted dataset inside LXC

 , , , ,

If you have installed Jellyfin inside LXC and have all your media mounted from a ZFS dataset inside your container, it’s possible that you are not able to delete files directly from the Jellyfin WebUi. In this case, you have to add the user “jellyfin” to a group with write access on your dataset. In my case, the group “nocin”.
