I need to edit Software and Updates' options in terminal. Namely the options:
Install updates from
- and automatical updates period, whether to check for them etc. etc.
Where can I find this options in the file system ?
The "Install updates from" option is basically your /etc/apt/sources.list
file. It can be edited with this command:
sudo nano /etc/apt/sources.list
Some lines are commented (with #
) when they are disabled. Just remove the comment from the front to enable them.
If you're referring to the other options on the page, I can only find some of them:
"When there are other updates" is this dconf key, time is in days:
/com/ubuntu/update-notifier/regular-auto-launch-interval
"Notify me of a new Ubuntu version" is in the file /etc/update-manager/release-upgrades
. Edit it with this command:
sudo nano /etc/update-manager/release-upgrades
There will be a line starting with Prompt=
. Change this to never
, normal
or lts
. It is also explained in the comments.
The other options I'm not sure of. I'm guessing that they are managed by a background service running as root. If you're interested, I found this with a dconf watch /
command while changing the settings.
