Install or remove addon from command line

Any reason not to use a vnc?

There's no clean way to do that AFAIK. You can physically move addon folders in and out of /storage / .kodi/addons, then use the built-in kodi 'updatelocaladdons' function (or restart kodi to update) and if necessary enable via json. It's certainly possibly via a script, but it would be a lot more effort for a one-off than installing a vnc.

Before krypton it was just a case of dropping folders into place, but there were deliberate changes to make that more difficult.

It's a bit tricky, but for self-contained binary addons like tvheadend without dependencies it's doable. Main problem is getting the latest ZIP . You can do this with that shell script:

#!/bin/sh
if [ $# -ne 1 ] ; then
  echo "usage: $0 addon-id"
  exit 1
fi

set -e

ADDON_NAME="$1"

DATADIR=$(xmlstarlet sel -t -v \
  "/addon/extension/datadir[@zip='true']" \
  /usr/share/kodi/addons/repository.libreelec.tv/addon.xml)

ADDONS_XML_GZ=$(xmlstarlet sel -t -v \
  "/addon/extension/info" \
  /usr/share/kodi/addons/repository.libreelec.tv/addon.xml)

wget -O - "$ADDONS_XML_GZ" | zcat > /tmp/addons.xml

VERSION=$(xmlstarlet sel -t -v \
  "/addons/addon[@id='${ADDON_NAME}']/@version" \
  /tmp/addons.xml )

ADDON_FILENAME="${ADDON_NAME}-${VERSION}.zip"

wget "${DATADIR}/${ADDON_NAME}/${ADDON_FILENAME}"

echo "addon $ADDON_FILENAME downloaded"

name it eg "get-addon.sh" and then run "sh get-addon.sh service.tvheadend42"

Then stop your current tvheadend (via systemctl stop service.tvheadend42), unzip the file in /storage/.kodi/addons, make sure all files in the bin subdir have executable permissions (otherwise to a chmod +x /storage/.kodi/addons/service.tvheadend42/bin/*), then start it via "systemctl start service.tvheadend42".

That's basically what kodi is doing as well.

so long,

fyi, you also need to symlink the systemd service file to /storage/.config/system.d

cd /storage/.config/system.d
systemctl enable service.system.docker
systemctl start service.system.docker
