I’ve tried to install Qubes OS via VM on my normal PC, but I cant get the internet to work.
Qubes OS has been found to work in a VM for some people, but it is not recommended to do so for non-testing purposes.
From my understanding the Qubes requires a specific type of hardware.
Qubes OS does have some specific hardware requirements, which can be found in the System requirements | Qubes OS doc. The most important parts are a 64-bit Intel or AMD processor with VT-x and VT-d or the AMD equivalent (you can find this out for Intel processors at Intel® Product Specifications), 16 GB of RAM, and a 128 GB SSD.
I don’t like to use a laptop, so how does the Mini compare to the Librem 14? Negative/positive sides?
Are there other mini pc’s that work good with Qubes or are Librem Mini the best alternative?
Qubes OS does not require specific laptops or computers in general. You can check the Hardware compatibility list (HCL) | Qubes OS for laptops or desktops that other users have found to work or not work. The most important aspects to look at there are the HVM and IOMMU columns.
Are 32GB ram enough or should I go with 64GB?
16 GB of RAM is recommended and is probably enough for over 95% of Qubes OS users.
I would like to use the same monitor, keybord and mouse. Are there any negative sides to use a KVM switch between my main pc and the Librem Mini?
Using a KVM switch should work perfectly fine, just be aware that using a USB keyboard may require additional setup to get working properly and additional security considerations.
Would the 24 word seed phrase be secure in the vault?
The vault is simply an AppVM that is set up so it does not receive any networking. You can consider how secure that would be for you.
Is it possible to install Binance and other crypto wallets on Qubes?
Software installation in Qubes OS is done much the same way as a normal GNU/Linux distro with the exception that software installed by a package manager is done in the TemplateVM. You can see the full instructions here How to install software | Qubes OS. If the software isn’t in the package manager, you can likely still install it by following the Linux installation instructions from the developers’ website.
Would consider myself kinda tech savvy, but with little to non Linux experience. How difficult is it to master Qubes OS for my use?
Qubes OS functions much the same way as any other GNU/Linux distribution with a few exceptions, such as: copying text and files between qubes, installing software, updating packages, using USB devices, and setting up VMs in general. You can check out the ‘How-to guides’ section of the Documentation | Qubes OS for in-depth explanations of how to do each of those tasks.
Where is the best place to start learning to get more comfortable with Qubes/Linux?
For me, the Documentation | Qubes OS is extremely helpful and goes into more depth and explanation than any of the videos that I’ve found. Other than that, I would say the best way to learn is just by using Qubes OS and asking questions on this forum if you run into any problems.
Anything I should know before ordering a Librem Mini and starting with Qubes?
Just know that the hardware requirements are not as extremely specific as they sound. As long as it has a 64-bit CPU with Intel VT-x and VT-d or the AMD equivalent, 16 GB of ram, and a 128 GB SSD, it has a good chance of working. However, Lenovo or Purism generally work the best and are less likely to have hardware problems. The Purism Librem Mini is listed in the Hardware compatibility list (HCL) | Qubes OS and works well.
Alternatively, I did a quick lookup and found a refurbished Lenovo tiny PC that meets all the recommended requirements and should work without any problems.
