The instructions are actually ok as written, as there is no right/wrong rule for where to download/expand the .tar.gz file into. FWIW - typically I use /var/tmp when I do it, but there is no right or wrong answer there.
In your case, I suspect you simply neglected to 'cd /home/weewx' in step-4 before running the sudo command. You need to be in the 'installed' location when you run the sudo command, not the 'source' directory your .tar.gz file expanded into. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
