I've edited file /etc/sudoers on N900 and now I receive this error:
sudo parse error in /etc/sudoers,,,,
I 've not root access, no usb or wifi access. How can I do to solve this problems?

Thanks a lot.

How did you edit it without root access?


it might help if you paste the contents of the file here...

I've edited the file with root access (sudo gainroot), after I've closed root session .....

Presumably he did have root access, but gaining it requires a working sudoers file (as does installing packages, etc) so once you've messed it up then you're stuffed.

R&D mode is a possibility, otherwise a reflash will be required.

Incidentally, you shouldn't edit /etc/sudoers directly - you should create a new file (or edit an existing one) in /etc/sudoers.d and the run update-sudoers. That includes a check for correctness, so should prevent this from happening. If you do need to edit the file directly, use visudo which will, again, check the file before saving it.

+1 to R&D mode, tried it myself when i was stuck in the OP's situation.

Could you explain to me what command I must launch?
flasher-3.5 --enable-rd-mode
and after?
Thanks a lot.

after that:
1. Boot normally
2. You'll be able to have root access
3. Revert your sudoers file
4. Restart and disable RD mode.

That should be it. You'll need to set the N900 into flashing mode first though.

thanks a lot !!!!!
I try and I send to you the result.

What program did you use to edit the file?

You should only use 'vi' to edit the file (using the command 'visudo'), as other editors can give syntax errors.
