 +### During the install 
 + 
 +#### Debian repositories changed from stable to oldstable 
 + 
 +See also https://github.com/YunoHost/issues/issues/1852 
 + 
 +At the very first step of the internet cube installer, the install is stuck with the following error: 
 +``` 
 +E: Repository 'http://deb.debian.org/debian buster InRelease' changed its 'Suite' value from 'stable' to 'oldstable' 
 +E: Repository 'http://security.debian.org buster/updates InRelease' changed its 'Suite' value from 'stable' to 'oldstable' 
 +E: Repository 'http://deb.debian.org/debian buster-updates InRelease' changed its 'Suite' value from 'stable-updates' to 'oldstable-updates'

 +``` 
 + 
 +Connect with SSH to your cube with the root account: 
 +```bash 
 +ssh root@192.168.1.46 
 +``` 
 +Enter `yunohost` as password. 
 + 
 +Then, just run: 
 +```bash 
 +apt update 
 +``` 
 +And then answer yes to the questions. 
 + 
 +#### VPN install failed 
 + 
 +See also https://github.com/labriqueinternet/install/issues/4 
 + 
 +In case there are special characters in your VPN account password:, the install will fail with the following error: 
 +``` 
 +Running: yunohost app addaccess vpnclient -u '******' 
 +'yunohost app addaccess' is deprecated and will be removed in the future

 +``` 
 + 
 +Connect to your internet cube with the admin account: 
 +```bash 
 +ssh admin@192.168.1.46 
 +``` 
 +Enter your admin password. 
 + 
 +Then, run the command that failed: 
 +```bash 
 +sudo ynh-vpnclient-loadcubefile.sh -u "<username>" -p "<password>" -c /tmp/config.cube 
 +``` 
 +(Please replace `<username>` and `<password>` with your credentials.) 
 + 
 +:!: Make sure to keep the quotes! 
 + 
 +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/) 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.

-If you have issues, or maybe you were able to find a fix for an issue, do not hesitate to contact us : https://chat.neutrinet.be+ 
 +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 
 +```
