For a reason I'd customised pacman.conf. I've deleted some line from here. And when I try to install any software it shows me error: config file /etc/pacman.conf, line 34: invalid value for 'SigLevel' : 'LocalFileSigLevel' error: config file /etc/pacman.conf, line 34: invalid value for 'SigLevel' : '='
I've changed some line before line 55. I can't remember which line I've deleted. But I can remember that I've changed some line before line 55. Would you please solve this?
It's a little late now, but for next time: before you make changes to a crucial configuration file, make a backup. It's a good habit to get into and only takes about five seconds.
sudo cp /etc/pacman.conf /etc/pacman.conf.bak
The backup can be used for reference if you need to check how the file was originally set up. If something goes wrong with your new config and you need to bail out, you can just mv the backup to overwrite your broken config.
I've copied and modified the config file. Now it is showing me error: GPGME error: No data error: GPGME error: No data error: GPGME error: No data error: GPGME error: No data error: no operation specified (use -h for help)
