Recover Data From A Multipass Qemu VM Image That Won't Start on MacOS M1/M2 (using linux)

Multipass on MacOS m1/m2 machines has had some ongoing issues with VM's working for awhile then failing to start. Previously, through some combination of these steps, I could get multipass working again and access my previous builds. After losing some data a couple of times this way, I've decided to ditch multipass for now. Unfortunately, this one time I had some data from an unfinished build that I had to get off one of the vm images that I could no longer start.

I tried a few ways of doing this solely on the mac, but I ended up copying the image file over to a desktop running suse/tumbleweed (distro shouldn't matter for these) and accessing the files there. Here are the general steps:

  • Find your vm image (need sudo). On a mac these should be in /var/root/Library/Application\ Support/multipassd/qemu/vault/instances/ - then in a folder with the name of your vm, grab the .img file and copy it somewhere and chown it to your local account.

  • Copy the

Django Recaptcha fix for SSL:CERTIFICATE_VERIFY_FAILED unable to get local issuer
'''
There are likely a few fixes for this but you are likely to see this error
if your app needs to reach out to an https server (in this case https://google.com)
and it cannot verify the ssl certificate.
The certifi package ( https://pypi.org/project/certifi/ ) provides a
curated collection of Root Certificates that avoids this.
pip install certifi - then in your settings you just need to set
the environmental variable for REQUESTS_CA_BUNDLE and SSL_CERT_FILE.
