Hi all, Just tried to install the 2026.1 version and got this error: ERROR conda.core.link:_execute(1033): An error occurred while installing package 'conda-forge::openmpi-4.1.6-hc5af2df_101'. Rolling back transaction: done LinkError: post-link script failed for package conda-forge::openmpi-4.1.6…

Hey @timanix , Thanks for all of this - everything looks as I'd expect, and these are all reasonable virtual package versions & system versions in your conda instance... That being said, since downgrading conda did fix the initial issue, I think we can table this for the time being - but I'll keep a…

Hey @timanix , yeah let's split this into a separate topic- I can go ahead and do that! I actually thought I had locked the announcement to prevent any replies, but maybe that doesn't apply to mods :sweat_smile:

Okay so just to get some more details @timanix , I'm guessing you're using the linux environment file (based on that last warning message)? Is this something you've ever run into with any prior QIIME 2 installs, or just 2026.1? And it looks like you updated (and then subsequently downgraded) your ver…

Hey @timanix , Thanks for following up; apologies for the delay! Okay so you are running on quite a modern version of ubuntu, it's interesting that downgrading conda had a positive effect... With regards to the outcome after you downgraded conda, you received those warnings & ClobberError but afte…

Hi @lizgehret [image] lizgehret: With regards to the outcome after you downgraded conda, you received those warnings & ClobberError but afterwards you were able to activate/use the environment as expected? Correct, I was able to analyse one dataset since. [image] lizgehret: Can you prov…

Hey @lizgehret , Thank you for keeping an eye on it - probably it is not crucial for 2026.1 release but may pop-up in later releses again. [image] lizgehret: please reach back out and let me know if you run into anything else unexpected! You probably already saw it somewhere, but with q2 ver…

Hello! Also ran into this issues while installing qiime, and again downgrading conda helped - this occurs both on WSL and on native Ubuntu.

Just wanted to chime in to say I also had the same install error using WSL, and that downgrading to conda 25.11 also fixed it for me (since you’re paying attention to if others have this issue).

I just wanted to say that I also had the same issue using RHEL, and downgrading also worked for me. Thanks for your work on these issues!
