Hello,
I’m following the instructions on a book for getting a basic machine learning setup. Previous installs were a diaster and managed to nearly break ubuntu (due to the root partition not being big enough), however I’ve rescued the system and I’m trying again. Currently I have 5.5gb free space so I figured I should be able to install the tools I need and store my code and models in another partiton.
I followed the steps outlined on the page by dropping the installation lines into a .sh file. After rebooting, I found that no tools were installed but drivers were upgraded. I tried to manually install the cuda stack and found out that the command failed
raymond@fathpc2018:~$ sudo apt-get install --yes lambda-stack-cuda

After some googling I found out to manually specify the packages to see which packages were having issues
So it looks like I either only have a 7.5 gcc repository avalible in my sources or I already have a 7.5 gcc installed. I think it’s probaly the first.
My first thoughts were that this was because my /etc/apt/sources.list was messed up after a failed ubuntu 20 upgrade. However I did manage to add back all the bionic sources through the “Software & Updates” application. I have not run into package installation errors until now. I googled around for possible issues and I still came upon the /etc/apt/sources.list being the issue but wasn’t able to find any problems with it. I enabled everything that I thought that may help in “Software & Updates”
Below is my /etc/apt/sources.list

I also spent some time trying to google for similar issues when installing the lambda stack. I found this post but no one provided an answer
