On Ubuntu my bitcoin core v.26 closes every few minutes without saving the downloaded blocks unless I close it first. Maybe a bug but how do I fix this? I updated version 22 to v.26 because v.22 was not opening anymore at all and crashed totally. So, now I have 31753 blocks left to download and it is taking forever by closing it before it crashes without any warning, so its like a roulette game and very time consuming! Please HELP fix this. Thanks guys!
