Hello,
Could you please try first to remove the brave data directory using the command:
rm -rf ~/.config/BraveSoftware and then try to add greek dictionary again?
I’ve tried different operating systems, sometimes the spell check download works fine and sometimes an error occurs. I still can’t figure out where the problem is coming from. I’m using Fedora and I’m trying to download the spell checker, but I’m getting an error. I put Debian on my computer, same error again. I run Fedora again on the computer, the spell checker downloads normally. I try various Linux distros and finally go back to Fedora, still get the error. I don’t understand what’s going on.
I installed Google Chrome, I downloaded the Greek spell check normally without a problem. I copied the Greek dictionary from the Chrome files, moved it to Brave’s Dictionaries folder and the spell check works normally.
.config/BraveSoftware/Brave-Browser/Dictionaries/
But this is a temporary solution. For me it is quite important to have the spell check of my language in the browser. So much so that I ended up using Firefox for a while. I hope the Brave team fixes the problem and we don’t have to go through such procedures. Other than that Brave is an amazing browser.
