Hello Community,

i recently got my N900 and i´m happy with it.

Today i upgraded severall apps using Extras, Extras-Testing and Extras-Devel and no is my sudoers file broken.

It says:

>>> sudoers file: syntax error, line 7 <<<
>>> sudoers file: syntax error, line 67 <<<
sudo: parse error in /etc/sudoers near line 7

How can i fix this?

I have installed rootsh, but sudo gainroot doesn´t work without a valid sudoers file and rootsh /bin/sh says that it is deprecated and is should use root or sudo gainroot instead.

The last apps i have upgraded (i hope i remember the right ones):
wizard-mounter
fmboost
fapn

Is there any other solution beside reflashing the device?
If reflashing is the only solution, do i loose my contacts if i reflash?

I do not have a microSD cad yet to make a backup.

Kind regards,

morlix

Well my first thought would be to uninstall the apps with the --purge flag. this hopefully will roll back the changes.

You could probably edit it in R&D mode

I have just had this problem, had wizard-mounter installed last night then removed it.

I ran update-sudoers as root

Except that if you can't get root, you can't uninstall them. You probably won't even be able to do so via App manager.

Thanks for the quick replies.

I can´t get root and the app manager says that no catalogue is installed.

@Rob1n: to get into R&D mode i have to flash device and i want to avoid that if possible

You shouldn't need to reflash the device - you need to run the flasher app, but I don't think you need to actually provide it with an image to flash. I've not tried it myself, but that's certainly the impression I've got from others.

I just typed root not "sudo gainroot" and it gave me root in terminal.

Then ran update-sudoers.

This was after a reboot.

You can enter R&D mode without flashing, but it will not help, as gainroot depends on sudo to gain root access. If you did not prepare in advance (sshd, another boot partition, some suid root binary that can run a shell), you are out of luck.

There are many programs that run as root on the system. If you can find a vulnerability in them that enables you to run arbitrary code, you might be able to fix the problem without a reflash.
