V64 Upgrade 502 Bad Gateway

[lifehacker]

Hi.

I just upgraded to v64 and when I tried the admin page, I received 502 Bad Gateway.
I logged in the server and ran sudo systemctl status mailinabox:
mailinabox.service - Mail-in-a-Box System Management Service

Anyone know how to resolve this issue?

Thank you in advance!

Searched and found the following post by matidau. I tried the recommendation and the issue is RESOLVED!

Steps I took from matidau’s post:
sudo apt list python*blinker*
sudo apt remove python3-blinker
sudo /usr/local/lib/mailinabox/env/bin/pip install --upgrade rtyaml "email_validator>=1.0.0" "exclusiveprocess" flask dnspython python-dateutil expiringdict gunicorn qrcode[pil] pyotp "idna>=2.0.0" "cryptography==37.0.2" psutil postfix-mta-sts-resolver b2sdk boto3
re-run Mail-in-a-Box setup.

Error with V62 upgrade

Hello, I am attempting to upgrade to .62. The upgrade seems to go perfectly well until until it attempts to install the management daemon when it tells me there is a .cache directory access error, and it fails on attempting to uninstall ‘blinker’. I have checked the permissions on the .cache directory which are rwx to the current user (ubuntu) as expected (0700). Below is a copy of the session: Mail-in-a-Box Version: v62 Updating system packages… Installing system packages… Initializing …

Thank you matidau!

Best regards
