How can I use an old Ubuntu distribution with repositories?

The repositories for older releases that are not supported (like 11.04, 11.10 and 13.04) get moved to an archive server. There are repositories available at http://old-releases.ubuntu.com.
The reason for this is that it is now out of support and no longer receiving updates and security patches.
I would urge you to consider a supported distribution. If your computer is too old in terms of memory or processor then you should consider a distribution such as Lubuntu or Xubuntu.

If you want to continue using an outdated release then edit /etc/apt/sources.list and change archive.ubuntu.com and security.ubuntu.com to old-releases.ubuntu.com.
You can do this with sed: sudo sed -i -re ‘s/([a-z]{2}.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g’ /etc/apt/sources.list
sudo apt-get update # && sudo apt-get dist-upgrade

What is the color palette on the C64?

Black = (0.0000,0.0000,0.0000,1)
White = (1,1,1,1)
Red = (0.5333, 0.0000, 0)
Cyan = (0.6666, 1.0000, 0.9333)
Violet = (0.8000, 0.2666, 0.8000)
Green = (0.0000, 0.8000, 0.3330)
Blue = (0.0000, 0.0000, 0.6666)
Yellow = (0.9333, 0.9333, 0.4666)
Orange = (0.8666, 0.5333, 0.3333)
Brown = (0.4000, 0.2666, 0.0000)
LRed = (1.0000, 0.4666, 0.4666)
Grey1 = (0.2000, 0.2000, 0.2000)
Grey2 = (0.4666, 0.4666, 0.4666)
LGreen = (0.6666, 1.0000, 0.4000)
LBlue = (0.0000, 0.5333, 1.0000)
Grey3 = (0.7333, 0.7333, 0.7333)

Setup iscsi

Init asd setup
https://www.unixmen.com/attach-iscsi-target-disks-linux-servers/
sudo apt-get install open-iscsi
iscsiadm –mode discovery -t sendtargets –portal 192.168.1.x
iscsiadm –mode node –targetname iqn_identifier –portal 192.168.1.x –login
Should be mounted, see where with fdisk -l
mkdir /media/open-e
add this to /etc/fstab.
/dev/sdb2 /media/open-e ext4 _netdev,rw 0 0

Disable/Delete
First choice: disable an iSCSI target:
iscsiadm –m node -T iqn_identifier –portal 192.168.1.x:3260 -u

Second choice: delete the target’s record ID
iscsiadm -m node -o delete -T iqn.identifier –portal 192.168.1.x:3260

*** Ubuntu 20.04 setup howto ***
https://www.howtoforge.com/tutorial/how-to-setup-iscsi-storage-server-on-ubuntu-2004-lts/
Setup:
apt-get install tgt -y
systemctl status tgt

Configure:
nano /etc/tgt/conf.d/iscsi.conf
backing-store /dev/sdf1 initiator-address 192.168.1.x incominguser iscsi-user password outgoinguser iscsi-target secretpass
Where:

The first line defines the name of the LUN. The second line defines the location and name of the storage device on the iSCSI Target server. The third line defines the IP address of the iSCSI initiator. The fourth line defines the incoming username/password. The fifth line defines the username/password that the target will provide to the initiator to allow for mutual CHAP authentication to take place.

Next, restart the iSCSI service to apply the changes:
systemctl restart tgt
Verify
tgtadm –mode target –op show

Install and Configure iSCSI Initiator
apt-get install open-iscsi -y
Discover
iscsiadm -m discovery -t st -p 192.168.1.x

define the name of the LUN device in initiatorname.iscsi file:
nano /etc/iscsi/initiatorname.iscsi
Add your iSCSI Target LUN name as shown below:
InitiatorName=iqn.identifier

Next, you will need to define the CHAP information that you have configured on iSCSI target to access the iSCSI target from the iSCSI initiator. The node configuration file will exist in the directory ‘/etc/iscsi/nodes/‘ and will have a directory per LUN available.

You can define it by editing the following file:
nano /etc/iscsi/nodes/iqn.identifier/192.168.1.x\,3260\,1/default
Add / Modify the following lines:
node.session.auth.authmethod = CHAP
node.session.auth.username = iscsi-user
node.session.auth.password = password
node.session.auth.username_in = iscsi-target
node.session.auth.password_in = secretpass
node.startup = automatic

restart the iSCSI initiator service
systemctl status open-iscsi

verify the iSCSI connection
iscsiadm -m session -o show
lsblk

login to the target iscsiadm --mode node --targetname iqn.2016-11:dss1.target0 --portal 192.168.1.x --login Then mount it (in my case it is /dev/sdf1)
