Here I'm creating a share “gutocarvalho” pointing to

/Users/gutocarvalho

on Guest (Ubuntu 22.04)

install open-vm-tools

apt update && apt install open-vm-tools -y
reboot

create a dir to mount the shared folder

cd  ~/Desktop
mkdir MacOs

now mount it

vmhgfs-fuse .host:/gutocarvalho /home/gutocarvalho/Desktop/MacOs -o subtype=vmhgfs-fuse 

fstab config

.host:/gutocarvalho    /home/gutocarvalho/Desktop/MacOs       fuse.vmhgfs-fuse    defaults   0    0

It's done!

In this example we'll expand a partition sdb1 mounted on the /opt directory.

on the proxmox side

The first thing to do is expand the disk using the proxmox UI, for that you'll need to turn off the kvm instance, expand the disk and turn it on again.

on the linux side

now with the os running you can

umount /opt
parted /dev/sdb
print
fix
resizepart sdb1 100%
quit
xfs_repair /dev/sdb1
mount /opt
xfs_growfs /dev/sdb1

that's it!

why?

Ubuntu 20.04 certbot package is ancient, the packge offers version 0.40.0 instead the current version is 2.6.x.

I need some resource like —preferred-chain that only exists in the recent version.

let's install it

apt remove certbot -f

installing depencies

 apt install python3 python3-venv libaugeas0

creating a venv

python3 -m venv /opt/certbot/

upgrading pip

/opt/certbot/bin/pip install --upgrade pip

installing the plugins

/opt/certbot/bin/pip install certbot certbot-apache certbot-nginx certbot-dns-cloudflare

creating the simbolic link

ln -s /opt/certbot/bin/certbot /usr/bin/certbot

creating a certificate for my zimbra

certbot certonly --dns-cloudflare --dns-cloudflare-credentials /etc/letsencrypt/cloudflare/nativetrail.conf -d '*.nativetrail.io,nativetrail.io' -n --force-renewal --preferred-chain "ISRG Root X1"

That's it ;)
