How to skip brave update via terminal?

[Forpli]

You could do it in synaptic package manager. Install synaptic

sudo apt install synaptic

and then search for brave-browser and click on all packages which are related to brave-browser. Then in the top bar click on "package" and enable " lock version". This will prevent brave-browser from being updated. Then click on apply.

Or you can try to follow the guide from littlekun and replace libreoffice with brave-browser in the command.

I can not omit some updates in Software Updater (Zorin 17.3)

I have experienced the same issue as well. The updater doesn't respond when manually unchecking packages to exclude from upgrade. To narrow it down I think it has something to do with the specific package and it's related packages. Until you uncheck all the related packages along with the one you are trying to exclude, the updater doesn't respond properly and have to force quit. In my case I was trying to exclude Libreoffice from the upgrade, after unchecking it, the updater became unresponsive…

It could also work with
'sudo apt-mark hold brave-browser', but I'm not quite sure if you need to enter the installed version of brave-browser here.
You could enter in terminal

apt list -i | grep brave-browser

to find the packages and then copy the names of the packages and paste it into the command
sudo apt-mark hold ...

I personally find it easier to use synaptic. When you later want to undo it and unhold brave-browser disable "lock package" in synaptic or replace 'hold' with 'unhold' in the command.
