I wanted to reinstall Firefox, so I uninstalled it using the Software Manager and tried to install it again. That's where the problems started. Uninstall was fine, but it just wouldn't reinstall! The bar went to 16% and cut to complete (and Firefox hadn't been installed). I did a little digging online and found that uninstalling Firefox from the Package Manager (and then installing it again) could help, but that didn't work either! When I try to install the firefox package on Package Manager, I get this message:
W: Failed to fetch http://security.ubuntu.com/ubuntu/pool/ ... _amd64.deb
404 Not Found
W: Failed to fetch http://security.ubuntu.com/ubuntu/pool/ ... .1_all.deb
404 Not Found
What can I do? I'm almost considering reinstalling Linux Mint, but given the luck I've had reinstalling things so far, I'd probably break my computer!
