 # Install a cube
-This procedure explains how to setup an Internet Cube and configure it with the Neutrinet VPN.
+This procedure explains how to setup an Internet Cube (Olimex [Lime2](https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-LIME2/open-source-hardware) or [lime](https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-LIME/)) and configure it with the Neutrinet VPN.
 ## Generate the VPN certificates
-In order to use our VPN, you need to follow [this registration process](en:vpn:order). You will generate a private key and obtain a personal VPN certificate.
+In order to use our VPN, you need to follow [this registration process](en:vpn:vpn-order). You will generate a private key and obtain a personal VPN certificate.
 In case, for some reason, you are reinstalling a cube and you want to reuse your VPN certificate, you can find them on a running (or dead) cube as user.crt, user.key, ca-server.crt and credentials in /etc/openvpn/keys.

 ## Troubleshootings
-### Issues with /tmp in RAM
-By default, the files `/tmp` folder are stored in RAM, which isn't a good idea when you have less than 1Gb available in a cube. See [tmpfs / armbian](https://forum.armbian.com/topic/10977-tmp-gets-eventually-full-how-to-purge-it/)
-You can disable this by running the following:
-```bash
-sudo sed s/^ENABLED=true/ENABLED=false/ /etc/default/armbian-zram-config -i
-sudo sed 's/^tmpfs/# tmpfs/' /etc/fstab -i
-```

 Then, run the command that failed:

 On the internet cube installer, retry the last step by clicking on the yellow button.
+#### The loading bar freeze
+If the loading bar freeze during the install, set the debug mode button to up.
+You will then see the details of the install and what the install procedure is doing.
+#### iptables/nftables doesn't seem to be working
+See https://chat.neutrinet.be/api/v4/files/3wxxx14t7fg6xjomitpyojk4fy/preview
+This is due to a kernel update: you just need to reboot the cube.
+Then, connect to the internet cube installer and retry the last step.
+### After the install
+#### Issues with /tmp in RAM
+By default, the files `/tmp` folder are stored in RAM, which isn't a good idea when you have less than 1Gb available in a cube. See [tmpfs / armbian](https://forum.armbian.com/topic/10977-tmp-gets-eventually-full-how-to-purge-it/)
+You can disable this by running the following:
+```bash
+sudo sed s/^ENABLED=true/ENABLED=false/ /etc/default/armbian-zram-config -i
+sudo sed s/^ENABLED=true/ENABLED=false/ /etc/default/armbian-ramlog -i
+sudo sed 's/^tmpfs/# tmpfs/' /etc/fstab -i
+```
+Then, reboot the cube:
+```bash
+sudo reboot
+```
+#### Unable to access some websites from the cube
+When your cube is connected to the Neutrinet VPN in IPv6, you might be unable to access some websites, although you are able to ping them. In addition, if you have a domain in .nohost.me or .nohost.fr, etc. your cube won't be able to update the DynDNS.
+Connect with SSH to the cube:
+```bash
+ssh admin@192.168.1.46
+```
+You need to reduce the MTU used to connect to the VPN:
+```bash
+sudo nano /etc/openvpn/client.conf.tpl
+```
+In the section `neutrinet` or `Custom`, add the line:
+```
+mssfix 1400
+```
+Then, restart the VPN client:
+```bash
+sudo systemctl stop openvpn@client.service
+sudo systemctl start ynh-vpnclient-checker
+```
+#### Roundcube fails to install on Lime 1
+Roundcube require more than 500M to install. On lime 1, it's necessary to add swap. You can do it by running the following :
+```bash
+sudo fallocate -l 1G /swapfile
+sudo chmod 600 /swapfile
+sudo mkswap /swapfile
+sudo swapon /swapfile
+```
+You can verify that swap is available :
+```bash
+sudo swapon --show
+```
+This should return a line about the swap.
+Then edit your fstab file to activate the swap on startup :
+```bash
+sudo nano /etc/fstab
+```
+Add the line :
+```bash
+/swapfile none swap sw 0 0
+```
