This question already has an answer here:
I've just installed Ubuntu Server 16.04.3. During the installing I kept getting the message:
select and install software failed
I have no idea why. I'm not an expert so I had no idea on how to find any reason why that kept happening. Anyway, the OS seemed to have installed just fine so I figured to just install OpenSSH through command line.
First I tried:
sudo apt install openssh-server. That resulted in the request of the CD. So I modified
etc/apt/sources.list and commented out the cdrom entry as advised here: https://ubuntuforums.org/showthread.php?t=2194719
Of course I did
sudo apt-get update after. Which strangly enough returned
Reading package lists... Done straight after.
After that I tried installing OpenSSH again, which resulted in:
Unable to locate package openssh-server.
So perhaps there was something wrong with my internet connection, but
ifconfig gave me the network interface with the ipaddress I expected. So I think that's working fine.
Next I found some advise to run:
sudo rm var/lib/apt/lists/* and do
sudo apt-get update after. Tried this, but no effect.
I have a feeling my installation simply has no repositories listed at all and therefor can't find any packages of course. Unfortunetely, if this is the case, I have no idea on how to fix it. Any advise would be welcome!
