Well then you're in luck! That's an easy problem to solve - simply download the classifier that corresponds with the version of QIIME 2 that you're using!
Navigate to the "data resources" section of the docs:
[https://docs.qiime2.org/2021.8/data-resources/#taxonomy-classifiers-for-use-with-q2-feature-classifier](https://docs.qiime2.org/2021.8/data-resources/#taxonomy-classifiers-for-use-with-q2-feature-classifier)
Then in the upper left corner, select the version of QIIME 2 that corresponds with the version you're running:
Finally, download the file(s) that you want, and you're all set.

Ah yes! It actually says "32+" - again, it all depends, and in the case of full-length SILVA, its definitely more of the "+" in our experience.

Just to make sure we're on the same page, the official guide is this one:

Hmm, there isn't any trick here, just `scp ` - I just double checked, there are no special flags or configuration things to take care of. You can find an older demo post here:

> Hey there @wlandesman --- SCP works over SSH, so you can just use the same port/user/password combo you use to log in. Here is an example of uploading a file (I just manually verified this using the 2018.11 AWS image): $ scp file\_to\_upload.qza qiime2@54.245.166.26:~/ qiime2@54.245.166.26's password: file\_to\_upload.qza 100% 0 0.0KB/s 00:00 This dropped file\_to\_upload.qza into my homedir on the server: $ ls file\_to\_upload.qza miniconda miniconda.sh Gi…

Something to keep in mind: QIIME 1 is not the same thing as QIIME 2 - they are two completely different projects. I think you'll have a hard time trying to make a QIIME 1 tutorial make any sense in QIIME 2.
Keep us posted!
