If a bug or feature leaves you wishing to halt updates temporarily or permanently, follow these great instructions below.
NOTE: as of v66.4 you need to disable rootfs verification prior to completing these steps.
- First, make sure you are installed with the CloudReady version you want to stay on
- Log in, and then press "Ctrl+Alt+T" to bring up a cmd line - you should see a yellow prompt like this:
- Now run the cmd
- This should bring up a green prompt like this:
- Next you need to make the file system write-able so you can make an edit. To do so, run the cmd
(You will be prompted for a password - the default is "chrome")
sudo mount -o rw,remount /
- Next we'll make a backup copy of the file we're about to change:
sudo cp /etc/lsb-release /etc/lsb-release.bak
- Finally, we can edit the URL that CloudReady looks for updates from, so that there'll be no response for an update check. To do this:
- Confirm you've disabled verity as mentioned above
- Enter the vim editor: sudo vim /etc/lsb-
(You might need to enter your password here when prompted)
sudo vim /etc/lsb-release
- Now that you're in vim, you enter "insert" mode by press "esc"
and then pressing "i" - this will cause it to act like a typical word processor where you can navigate with arrow keys and enter or delete characters inline.
- Find the two lines that says "...CHROMEOS_AUSERVER..." and "...CHROMEOS_DEVSERVER..."
- In each of those two lines, make an edit that will cause the URL there to be invalid.
(I personally like to change it from "cloudready-free-update-server" to "cloudready-no-update-server", but as long as you make a relatively random choice updates will cease)
- Now that you've made your change, press "esc" again and then press ":qw" following by "enter" to tell the device you want to save those changes
- Assuming nothing went wrong above, now reboot
- Those changes should now prevent updates. If you want to re-enable updates you just need to take your backup copy and copy it back into place, replacing the edited version:
sudo cp /etc/lsb-release.bak /etc/lsb-release
