Some random notes on trying (and failing) to get Proxmox as host with 5700G APU GPU PCI Passthrough to Ubuntu guest VM working:
References:
Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma
You can get the list of supported formats with:
ffmpeg -formats
Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:
Here are the steps I took to upgrade my nodes when the time came. Make sure that your apt upgrade and apt dist-upgrade don't have any errors.
Additionally, on one of my nodes, I had to confirm the grub install location. So It may be good to do this prior to upgrading by confirming the mount point of your boot disk.
apt remove --purge r8168-dkms -y
rm /etc/modprobe.d/blacklist-r8169.conf
sudo sed -i 's/GRUB_CMDLINE_LINUX="r8168.aspm=0 r8168.eee_enable=0 pcie_aspm=off loglevel=3"/GRUB_CMDLINE_LINUX=""/' /etc/default/grub
update-grub

Here is a bash-only YAML parser that leverages sed and awk to parse simple yaml files:
function parse_yaml {
local prefix=$2

sed -ne "s|^\($s\):|\1|" \
-e "s|^\($s\)\($w\)$s:$s[\"']\(.*\)[\"']$s\$|\1$fs\2$fs\3|p" \
-e "s|^($s)($w)$s:$s(.*)$s$|\1$fs\2$fs\3|p" $1 |
