I'm technically on a LAN so why is my data usage spiking when I'm uploading roms

You'll have to ask Comcast (?) about this - it would be absurd if this is classified as 'internet usage'.

lubuntu is giving me permission denied when copying files to the retropie sd

Where are you copying the files ?

Home/pi/retropie/roms

Check the permissions on the folder - if your regular user doesn't have access to it, then use sudo to start a file manager and do the copying. You'll have to fix the roms folders' permissions on the Pi - but this can be done easily.

sudo chmod -R ugo+rw

I used this command and it worked. So ollie just have to run the done easily
And I should be good to go thanks!

sudo chmod -R ugo+rw

That's not the correct way to do it and if you've done it against the whole partition you might have problems later on.

I did it with dreamcast.... oh boy lol

[UberLumby]

@UberLumby sudo chmod-R ugo+rw/media/lubuntu/retropie/home/pi/retropie/roms/dreamcast is what I did exactly

It seems alright so far

@UberLumby never mind lubuntu is giving me permission denied when copying files to the retropie sd LOL

Linux distinguishes users by their user id (uid). If your uid on Lubuntu is different than that of pi on RetroPie (normally 1000), you won't have write access to it even if the username on both systems is the same, e.g. you made a pi user on Lubuntu just for that.

Vice versa, you would have full access if the usernames are different but the uids are equal, say "pi" on RetroPie and "lubuntu" on Lubuntu both had the uid 1000 on their systems.

You can see the uids and gid (group ids) of files and directories with the -n ("numeric ids") option of ls:

$ ls -n
drwxr-xr-x 6 1000 1000     4096 Apr 28 02:38 RetroPie
drwxr-xr-x 7 1000 1000     4096 Sep 19 19:01 RetroPie-Setup

If your uid and gid differ on RetroPie and Lubuntu, you could change the ownership of the directories only temporarily, and change them back after working with the files:

sudo chown -R lubuntu /media/lubuntu/retropie/home/pi/retropie/roms/dreamcast  # use your username or uid for "lubuntu" here.
# Do your stuff.
sudo chown -R 1000 /media/lubuntu/retropie/home/pi/retropie/roms/dreamcast     # Provided that pi's uid is 1000 on RetroPie

To me this is more "elegant" than the chmod way, as it doesn't mess with the files permissions. But this may be mere preference. And as with chmod, be sure to not to use it globally as it can mess up thinks equally bad. Use it only on directories where all files and subdirs have the same uid from the start.
