Installation guide for OxOffice Online v4 Community on Ubuntu 20.04 in PVE LXC

Please download "ubuntu-20.04-standard" LXC template on your PVE first

You can see Ubuntu 20.04 LXC template in "CT templates" section

Create a new CT using "Create CT" button

Start created CT, login as root and excute following commands to install needed programs and OxOOL Community edition:

apt update
apt upgrade -y
apt install vim openssh-server net-tools curl gnupg2 wget -y
# Chooese yes if you get any service restarting prompts
curl http://www.oxoffice.com.tw/deb/OSSII-2022.key | sudo apt-key add
cd /etc/apt/sources.list.d/
wget http://www.oxoffice.com.tw/deb/oxool-community-v4-focal.list
apt update
apt install oxool -y

Start OxOOL Community edition service when booting and reboot

systemctl enable oxool
reboot

Check if OxOOL Community edition starts normally

netstat -tlnp

You should get some results like this:

tcp6     0    0    :::9980		      :::*   	LISTEN   644/oxool

P. S. When steps above are finished, you can use "More"→"Convert to template" to generate new LXC template that contains OxOOL Community edition.
