Description of my issue

Hello, Yunohosters! After attempting to upgrade Wekan from v7.49 to v7.51, I was no longer able to visit the app (I believe due to a 502 Bad Gateway on the front end). These are the steps I followed.

I gather (MongoDB v5.0.6 exited with status code 62 - #4 by Tarif_Ezaz - Installation & Upgrades - MongoDB Developer Community Forums) that mongod.service exiting with error code 62 means that the major version of MongoDB was bumped between those versions, leaving my data unreadable by the new version. This is what motivated me to try to downgrade Wekan. That still may be the way to go; presumably if I can successfully install v7.49, I can upgrade to 7.50 and then 7.51 and all will be well.

  • ETA: I tried uninstalling MongoDB and its systemd service, and then installing v7.49. This failed. Logs are pasted here: https://paste.yunohost.org/raw/usepugaxif . Puzzled as to why the install script would fail to create the /var/lib/mongo directory or the mongod user.

Anyone have any guidance here? I’d love to be able to retain my data. Thanks in advance!

Having the same issue.

Any input would be much appreciated…!
