[RESOLVED] Notice to Multi-User System users regarding QIIME 2 2022.8 Installation

Hi all,

We were notified this morning of a user permissions issue for folks who are utilizing a multi-user system. A detailed description on the issue can be found here:

We are currently working on a fix for this issue, and will be deploying a patch release with the fix early next week. For all folks who are on a multi-user system, our immediate recommendation is not to upgrade to QIIME 2 2022.8 until we've deployed our patch release.

If anyone on a multi-user system does need to utilize the 2022.8 update, the way that this multi-user error can be dealt with is to create a new temp folder (e.g., in your home directory) and export it as an environment variable by running the following:

mkdir $HOME/tmp/
export TMPDIR=$HOME/tmp/

Please note that you'll need to either re-run this command each time you close/re-open your terminal, or add this to your relevant shell start-up file (e.g., ~/.bashrc, ~/.zshrc, ...).

We apologize for any inconvenience this may cause! Please let us know if you need any assistance navigating this stop gap solution prior to the patch release. Thanks!

-The QIIME 2 Core Development Team :qiime2:
