Hi i fucked up my permissions this day by the command:
sudo chmod -R 777 /
And now i cant access sudo, su or any super user command
so now i need to reinstall my machine…
but can i reinstall it without losing any data in my home folder?
Hello @FrodoToto,
Which OS and version did you install ? Ubuntu ? Debian ?
The most simple could be to download your files and reupload them 
Its ubuntu 16.04
And we are talking 4-5TB so its not really an option
If you ran 777 on the entire /(root) mount… I m afraid you’re duped. Nothing you can really do other than do a reinstall of the OS. I have done this before on so many machines by way of late night and lack of coffee… it’s a drag every time.

if it was local server id say there is one idea but as i dont think u are running it locally.
you is in bad situation sucks but yeah clean install the only way to fix it.
If in the very rare change you’re using online.net
They offer a C14 storage option for their dedis.
I had to backup all my data (3.5tb) a few months ago.
They have a 20tb “temporary storage” space that you can store data on for 14 days. I was able to use that temp space while I rebuilt and then transfer back at the full gigabit. In total cost me about €1 - they only charge for creating and deleting the temp storage, no charge for the data in temp.
