Installing microk8s in an LXC container

I wanted to run Microk8s on a Proxmox 6 host inside of an LXC container. These are my notes from the journey.

Create a privileged LXC container through the Proxmox web interface

Enable nesting and FUSE
- In Proxmox UI, select container, then Options > Features > Check nesting and FUSE boxes

SSH into the Proxmox host and edit the container's config in /etc/pve/lxc/.conf
- Add the following lines

lxc.apparmor.profile: unconfined

Open a webpage that uses the CA with Firefox
Click the lock-icon in the addressbar -> show information -> show certificate
the certificate viewer will open
click details and choose the certificate of the certificate-chain, you want to import to CentOS
click "Export..." and save it as .crt file
Copy the .crt file to /etc/pki/ca-trust/source/anchors on your CentOS machine
run update-ca-trust extract
test it with wget https://example.com

On Manjaro (arch) the location for the certificates is: /usr/share/ca-certificates/trust-source/anchors (low priority) or /etc/ca-certificates/trust-source/anchors/ (high priority) and the command to update is update-ca-trust extract.

Problem

You have installed GPG, then tried to commit and suddenly you see this error message after it:

error: gpg failed to sign the data
fatal: failed to write commit object
