A fully working GNUNet virtual machine on Ubuntu 19.04 Server. Both the OVA is available (note: could be available, if anyone shows interest) for download as are step-by-step instructions to do it yourself.
mkdir /opt/u64
wget "http://releases.ubuntu.com/19.04/ubuntu-19.04-live-server-amd64.iso" -O /opt/u64/u64.iso
You can totally do this the 'normal' way via the virtualbox GUI also. I like command line so I learned and created this way. It's tried and tested and I use it to make 'burner' vms.
export VM_BASEDIR="/opt/u64"
export VM="u64"
sudo mkdir $VM_BASEDIR
sudo chmod a+rw $VM_BASEDIR
#create the vm and the hd to attach. note you can set size of both hd/ram here. The defaults i set work fine.
VBoxManage createvm --name $VM --register --basefolder $VM_BASEDIR
VBoxManage createhd --filename $VM_BASEDIR/$VM.vdi --size 25000
VBoxManage modifyvm $VM --memory 2048 --ostype "Ubuntu (64-bit)" \
--vram 16 --pae off --x2apic on
#create the SATA and IDE interfaces. Attach ISO and VDI to them.
VBoxManage storagectl $VM --name "SATA" --add sata --controller IntelAHCI
VBoxManage storageattach $VM --storagectl "SATA" --port 0 --device 0 --type hdd --medium $VM_BASEDIR/$VM.vdi
VBoxManage storagectl $VM --name "IDE" --add ide
VBoxManage storageattach $VM --storagectl "IDE" --port 0 \
--device 0 --type dvddrive --medium $VM_BASEDIR/u64.iso
#create NAT network, turn it on, connect our vm to it.
VBoxManage natnetwork add --netname natnet1 --network "192.168.15.0/24" --enable
VBoxManage natnetwork modify --netname natnet1 --dhcp on
VBoxManage natnetwork start --netname natnet1
VBoxManage modifyvm $VM --nic1 natnetwork --nictype1 82540EM --cableconnected1 on --nat-network1 natnet1
#set up 'host only' interface on host, then set this VM to have an adapter connected to that net.
VBoxManage hostonlyif
VBoxManage modifyvm $VM --nic2 hostonly --hostonlyadapter2 vboxnet0
VBoxManage startvm $VM
Unfortunately I could not script this part. I definitely tried, but the 'unattended install' parts of virtualbox are still in the works. There's nothing particular to GNUNet to do here, just click your way thru the usual timezone and username settings, they aren't important. Do Not pick 'gnunet' as the default username though, as we will use that username in next section. Once install is complete and you can successfully boot into it via GUI virtualbox, I like to ssh to it instead (copy-paste works, for starters):
arp -a -i vboxnet0
...will get you your vbox's IP address if you dont know what it is. copying your ~/.ssh/id_rsa.pub into the vm's ~/.ssh/authorized_keys (make it if it doesn't yet exist) is also nice for passwordless login.
You can also start the vm 'headless' from command line so you dont have to have virtualbox GUI open anymore. With vm shut down, try:
VBoxManage list vms
(it's called u64 i think, unless you changed it). Start with:
VBoxManage startvm $VM --type headless
..$VM being your vm name. You can shut it down with:
VBoxManage controlvm $VM poweroff
Its important to note here that though these instructions were found piecemeal other places (official documentation mostly) - they Are Not an exact match and the instructions I found didn't work to begin with. For example nothing worked initially because libtool is now split into two packages on Ubuntu, libtool and libtool-bin and the errors were less than lucid about what was wrong. TL;DR these are updated instructions that i found elsewhere and initially didn't work and I had the joy of figuring out why everything was screaming error and segfaulting and so on for days so that I could compile this.

Note: you can change default ports above. There's so many things one can tweak. This isn't a tweaking guide, its a 'from zero to node you can use' guide.
then you actually flip the 'on' switch with:
sudo systemctl daemon-reload; sudo systemctl start gnunet.service
...then you can see the action in..syslog. :/
tail -f /var/log/syslog | grep -i gnunet
This solves the "vpn-9252 ERROR `gnunet-helper-vpn' is not SUID, refusing to run." etc seen in log. gnunet-suidfix is installed but if I run as user, I get permissions errors. If I run with root, it tries to suid files in /usr/lib (gnunet bins aren't there). I never could make sense of this so I just copied out the files that it was trying to change and suid' them myself:
sudo chmod u+s /usr/local/lib/gnunet/libexec/gnunet-helper-exit
sudo chmod u+s /usr/local/lib/gnunet/libexec/gnunet-helper-nat-server
sudo chmod u+s /usr/local/lib/gnunet/libexec/gnunet-helper-nat-client
sudo chmod u+s /usr/local/lib/gnunet/libexec/gnunet-helper-vpn
sudo chmod u+s /usr/local/lib/gnunet/libexec/gnunet-helper-dns
sudo chmod u+s /usr/local/lib/gnunet/libexec/gnunet-service-dns
...Aaaand that's it! If you made it this far, congrats slugger take a victory lap ;)
I had a pretty tight envrionment in which I was testing this and so this may not apply to you. If you have a ton of messages in the log about IPV6 failing, read on:
i tried a mil things to get the log to shut up about ipv6 fails. there is a 'DISABLEV6' line in nearly every single conf file in /usr/local/share/gnunet/conf.d/. Which means in every subsection of the gnunet.conf...
and None had any effect whatsoever on the use of ipv6! LOL
I finally disabled UDP entirely
by removing 'udp' from '[transport] PLUGINS' and that stopped it from trying ipv6 for whatever reason.
...So, edit your /etc/gnunet.conf file and look for the [transport] section. delete 'udp' from PLUGINS list.
getting gnunet-gtk compiled and installed was as easy as this:
cd ~/gnunet_installation
git clone https://git.gnunet.org/gnunet-gtk.git/
sudo apt -y install libgtk-3-dev libgladeui-dev libgl1-mesa-dev
cd gnunet-gtk
./configure --prefix=$GNUNET_PREFIX --with-gnunet=$GNUNET_PREFIX
make
cd ~/gnunet_installation/gnunet-gtk
sudo make install
sudo ldconfig
getting mysql datastore setup: (note the 'identified by' part. you need to set a password.)
sudo apt install mysql-server
sudo mysql -u root -p
#press enter at password prompt
CREATE DATABASE gnunet;
GRANT select,insert,update,delete,create,alter,drop,create \
temporary tables ON gnunet.* TO gnunet@localhost identified by \
'your_cool_password_here';
FLUSH PRIVILEGES;
in ~, create file .my.conf. change user/pass to yours.
echo """[client]
user=$USER
password=$the_password_you_like
""" > ~/.my.cnf
NOTE: where this file is looked for is determined by /etc/gnunet.conf If you followed by above instructions, there's a [datastore-mysql] section already there for your tweakage.
