I'm trying to extract a rar file is first time is opened then its closed and to reopen the file is failed." an error occured while loading the archive manager" this alert message displayed
Install unrar to open and extract rar archives.
- Open the terminal with ctrl + alt + t
sudo apt install unrar
Now file-roller should open and extract rar archives without error.
If you cannot install unrar, you need to activate the multiverse repository; but, I assume you have them activated as they are by default.
