You reinstall the router with RouterOS and then you have a clean install without Dude but also without any own configuration. You will have to restore your backup config and if you don’t have one then you have do it manual for each rule and setting.
if you had just installed Dude and all free space was gone - i think only reinstall will help, but if you was using dude for some time and it’s database grown up then you can try to do this: 1) stop dude service 2) delete dude database from files (it will free some place) 3) delete dude package
I have worked with MikroTik Products for the last 13 years. I just signed up to respond to this issue!
It is a very simple task to remove “Dude” from the mikrotik.
Simply go to a terminal, and then
type “/system/package”
then… type “print”
you will see a list pop up with the word you are looking for. If you notice there is a
number to the left of the word “Dude”.
Now… Type “Remove 3” for example. change 3 to whatever that number is on that line!
Then issue a reboot to the mikrotik and there you go. Problem solved without a reinstall.
