First check if you have swap configured:

swapon --show

IF empty you can create for example 256MB swap file with following commands:

fallocate -l 256M /var/swap
chmod 600 /var/swap
mkswap /var/swap
swapon /var/swap

You can again check if swap is properly configured:

#swapon --show
NAME      TYPE SIZE USED PRIO
/var/swap file 256M   0B   -2

#free -m
              total        used        free      shared  buff/cache   available
Mem:            480         109         140           9         229         312
Swap:           255           0         255

For example if you want to download rom files from specific site and to ignore all other file types you can use:

wget -A rom -m -p -E -k -K -np http://files.swos.eu/amiga/kickroms/

Additional extensions you can separate with comma (,).

Please edit your /boot/config.txt file with following contents:

# uncomment to force a console size. By default it will be display's size minus
# overscan.
framebuffer_width=1024
framebuffer_height=600

hdmi_force_hotplug=1
#hdmi_ignore_edid=0xa5000080
hdmi_cvt=1024 600 60 3 0 0 0

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2
hdmi_mode=87

First to test how the renaming will look like you can use the command with -n switch as:

rename -n 's/\.([^.]+)$/.\L$1/' *

If you are satisfied just remove “-n” and all files will have it’s extensions renamed to lowercase.

rename 's/\.([^.]+)$/.\L$1/' *

To renew all your due certificates manually you can use:

certbot renew

To remove one domain from the list of certificates you can use:

certbot delete

You will be presented with a list from which you can choose which domain should be removed from configuraiton.
