Frequently Asked Questions about Clouds

On this page we have collected some frequently asked questions about your own cloud.

1. Creating your own cloud with Raspberry Pi

Questions and answers related to this tutorial can be found in this category.

How do I update the software on my Raspberry Pi?

New updates to Raspberry Pi OS, the Pi's operating system, are released at irregular intervals. In order to fix bugs and security vulnerabilities, you should install these updates. Please use the following commands to install updates:

sudo apt-get update

sudo apt-get -y upgrade

I would like to buy a different model of Raspberry Pi. Is that possible?

Basically yes. The newer models are a bit more powerful and therefore more suitable. The important thing is that the Raspberry Pi has a LAN port or WLAN compatibility so that you can connect it to the internet.

Can I use the instructions with other mini computers?

We have only tested the instructions exclusively with the Raspberry Pi. However, many of the steps from 3.3 onwards can be done in a similar way on other systems. However, you should not rely on this. We would like to reiterate that the instructions are based on your own cloud with the Raspberry Pi.

Do I need to include the square brackets, e. g. in "--password=[YOUR MYSQL PASSWORD]" as well?

No, absolutely not. If the square brackets tell you what to put there, replace both the text and the square brackets with what you want to put in.

I have forgotten my MySQL password. What should I do now?

This is annoying, but if you follow a guide like this, you can set a new password. It's best to write it down somewhere safe. And don't forget: Choose a strong password. You can generate passwords with a password generator, for example.

I would like to make further changes myself. How can I access the seafile user?

If you want to log in as user seafile with su seafile, you will be asked for a password. To log in as seafile without a password, please enter the following command:

sudo su seafile

However, we recommend making any changes as user Pi.

I am getting an error message from update-rd.c and insserv. What should I do?

Are you getting the following error message?

update-rc.d: using dependency based boot sequencing

insserv: warning: script 'seafile' missing LSB tags and overrides

This is a warning that should not affect the functionality of your cloud. However, you can use the following command to remove the (unnecessary) program that causes the second part of this message:

sudo apt-get remove insserv

What can I do if I cannot set up port shares?

If the "Port shares" item does not appear in your router's menu, or you cannot enable port shares, you will not be able to use your cloud. This could be due to a so-called DS-Lite connection. With this slimmed down internet connection, you will not be able to receive incoming connections.

Please contact your internet provider to change your internet connection.

How do I switch off the Raspberry Pi?

For cloud operation, the Raspberry Pi should be running continuously. If you still want to shut it down, please execute the following command and wait for about 1 minute before disconnecting the Raspberry Pi from power:

sudo shutdown -h now

Why do I get a security warning in the browser?

If you are using a so-called self-signed certificate, the usual place to confirm that this certificate is the right one for your cloud URL is missing. The browser will therefore display a security warning. You can ignore this by creating a security exception rule.

Your connection is encrypted in the same way, but it may be easier for third parties from your network to connect to it. Instead, you can get a certificate signed for free, such as via Let's Encrypt.

2. Cloud Hosting

Questions & answers about cloud providers that offer you ready-made solutions can be found in this category.

What exactly is such a cloud hoster or provider?

We introduce you to some cloud providers/services. These are companies that have their own datacenters. You pay a monthly fee to use some of the storage space on one of these servers. You can also install your own cloud with the right cloud software.

When should I choose a cloud provider over having my own cloud at home?

If you are not confident in setting up your own cloud server following our instructions, a cloud service provider is probably a better alternative. Some cloud service providers make it really easy to set up, and they also take care of updates for you. Disadvantages include higher costs and the fact that you store your data on their servers, which could theoretically be accessed by the provider.

3. Cloud software

You still have questions about the cloud software? Maybe you can find the answer here.

Does it matter which cloud software I use?

The cloud software you choose will affect the performance of your cloud and the look and feel of the user interface. For example, some products are more suitable for experienced users, while others can be used by beginners.

Which software is easiest for a beginner to use?

Owncloud has a particularly easy-to-use user interface. You almost never have to access the console, but have direct access to all the main functions through the software. Nextcloud is based on Owncloud and is for many a bit easier to use.

Seafile also has a comprehensive web interface, but updates have to be applied through the console. Seafile requires a little more experience with servers.

You should also have a basic understanding of FTP for the FTPbox. Apart from that, it is also quite easy to use. However, it offers considerably less functionality than Owncloud, Nextcloud & Co.
