gnupg – Ubuntu Partition – Information Security Stack Exchange

After the recovery of the operating system is disrupted by my Ubuntu partition, I undertake to restore my files, but I have not been able to restore Ubuntu with my files. My question is: is there a way to restore? Ubuntu with all my data?
In the case of a NO, I have my keys in my files, could I recover my private keys from the private-keys-v1.d file?
