v6.44 [stable] is released!

[martinclaro]

Upgraded a RB851G (both RouterOS and RouterBOOT) from 6.42.12 today. I get errors every time I try to save a backup file (both local and cloud, same error).

[admin@xxxx] > /system backup save 
Saving system configuration
Configuration backup saved
08:54:42 echo: backup,critical error creating backup file: could not read all configuration files

Try to regenerate the ssh host keys:

/ ip ssh regenerate-host-key

Thank you @eworm! You nailed it! I was just reading this other thread where you had the same issue, but for a previous version.
