Help!! Accidentally dragged a random directory into another and now its all broken

dankcushions

it looks like you've dragged /home/pi into /opt. just drag that /opt/pi directory back to /home

however note that you're using a pre-built RetroPie system, and a third party image, neither of which we support, as per https://retropie.org.uk/forum/topic/3/read-this-first, so please do not post any more support questions until you are using our install. my advice above may not be correct as we have no idea how your image is set up, so i would take this opportunity to start again from the official image :)

Thanks! Just as soon as I work out to undo what mount this SD card (installing some homebrew package now...) I'll move it back and hopefully that will work.

Does this mean there should be no /opt/pi/ directory at all ?

not on official RetroPie, certainly.

cyanxx

@dankcushions Great, good to know.

(Sorry btw, had no idea third-party images for Retropie were even a thing)

cyanxx

@dankcushions I know this is not a retropie question... but I have mounted the SD card on my mac and can view it at last. But I cannot access the contents of the /home/pi/ directory as its protected. Do you know if there is a way I can login somehow or am I screwed? No worries if you dont know, just thought I'd ask.

cyanxx

Ok, managed to access the pi directory via another raspberry pi.... copied it all back into the right places. Still a kernel panic though and it wont boot
Guess it could be starting from scratch after all... :(

My sympathies and good luck with that. And don't forget to ⚠️backup⚠️ your system after you've set up everything, and in regular intervals after that.

cyanxx

@Clyde appreciated. Managed to connect the SD card to another raspberry pi so copying all the roms and configs over to a portable HD now. Then going to reflash it with base retropie and re set it all up again 🤞

Is there a recommended way to back up? Can't think how to do it without just dragging a bunch of stuff over SFTP (what screwed me in the first place)

@cyanxx https://retropie.org.uk/docs/Updating-RetroPie/#making-a-backup. And don't use the root account for transferring ROMs.

Thanks. So connect via SFTP using the pi account yes? What is the pitfall in using root incidentally?

Well, for starters you wouldn't have been able to copy your /home/pi to /opt, since the permissions on /opt would have prevented it.
As a rule, you don't use an administrative account for day to day operations of your system. You don't need it and you can accidentally break your system by removing important files or changing permissions on system files.

Use root only when are explicitly doing system configuration or update and, even then, prefer the sudo command instead of logging in directly as root.

cyanxx

@mitu I was actually logged in as pi via Filezilla when it happened (dont have root). Thats all the company I bought it off provided, but it worked everywhere so I didn't chase it further. Good advice though, I understand the merits.

So if I want to update config files in /opt/retropie/configs/ (that path from memory sorry) I was just copying them off via SFTP - updating on my mac and then copying back. Is that how you would do it?

mitu

@cyanxx You don't need SFTP for that, you can access the RetroPie file shares (ROM folders/configs) from your macOS system - see https://retropie.org.uk/docs/Transferring-Roms/#samba-shares. That should be the preferred method.

cyanxx

@mitu ah sweet. Perfect. I did try that before but couldn't get it to work. Hopefully now I'm on the official image it'll work properly. Thanks!

cyanxx

@mitu @dankcushions I'm saving the contents of

/home/pi/retropie/roms/
/opt/retropie/configs/

Can you think of any other directories I should save before I wipe the SD?

mitu

The BIOS folder might be useful.

My sd card
for retropie is asking for a password. Help

mitu

@montelcow Please open a separate topic instead of barging in on existing ones. Provide the information requested in https://retropie.org.uk/forum/topic/3/read-this-first.

Hello my sd card i have is asking for a password..

cyanxx

@montelcow sorry, I had to use another raspberry pi in order to access the protected directories. Couldn't work out how to do it via mac. Assuming you are meaning you are trying to access the sd card not from the retropie. But as mitu says, perhaps if you start a topic on it someone will help.
