I’ve used Keepass or Keepass XC for years. They are great!

Are the bolts on the inside all tight?

All good comments. Get any chimneys regularly cleaned by a chimney sweep. Get Heating systems checked by a pro every year. If you are heated/cooled by air, replace the filter(s) regularly. If you are heated by hot water, drain the system regularly. Drain the hot water tank regularly. Grease/Oil almost anything that moves. Service the lawn equipment regularly. Keep everything sharp.

Linux Mint, it just works
