environment variables not read?
although I am setting BORG_PASSPHRASE,
export BORG_PASSPHRASE="my passphrase"
borg create asks for it during execution
What could that be?
Usually it is a problem in the script and the most frequent issue is forgetting to export (not the case here, though).
I am not aware of any bugs with borg not considering a BORG_PASSPHRASE in its environment.
Maybe some typo?
Which borg version are you using and where did you get it / how did you install it?
I am using 1.1.16, loaded from main web page referred raspbian site I am not (yet) scripting, just manually testing
"loaded from main web page referred raspbian site" - can you give a link?
Also: try to reproduce the issue and then copy and paste the commands you used in here (maybe use a passphrase you can publish, not the "real" one).
Also if you are testing. This is the community repo, so the issue is clearly wrong here. If you use plain Borg that should be moved to the borg repo. Otherwise report the issue to the tool you actually use.
Oh, oops, @rugk is right (didn't notice that). :-)
To clarify: the community repo is mostly to update the link list seen on the front page.
