Using keys generated on putty for access to a linux server was always painful in my (fortunately ancient) experience. I always added cygwin to my windows systems to get a real shell and ssh client rather than the putty kludges. I'm sure what you're trying is doable, you just need to find the magic incantation to generate a key that a modern Linux sshd supports. It's also possible to generate your key on linux and import it into putty's setup the other way, but it's been so many years since I had to use putty that my memory is hazy on how to do that.
I don't see any difference in users between raspios and ubuntu other than the name of the built-in canned default user. They're both debian(ish) under the hood. Resetting the mariadb root password is something I 'have' done occasionally when I mess up the initial setup. See if (this link) <https://www.digitalocean.com/community/tutorials/how-to-reset-your-mysql-or-mariadb-root-password> helps any. If it's me, I'd work the problems one by one rather than punting the base os by reflex out of frustration. But consider adding cygwin and ssh to your windows setup if you're going to do a lot of ssh'ing into linux hosts. It'll make your life 'much' easier. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
