'Moving to a New Box' guide has some issues

[nicholashead]

I tried to follow the guide, and ran into the same issues the person at https://discourse.mailinabox.email/t/testing-restore-to-new-vps-fail/1212/4 ran into:

• Restore destination directory /home/user-data already exists. Will not overwrite. error after running sudo -E duplicity restore file:///path/to/copied/files /home/user-data/
• Error '[Errno 17] File exists' processing ssl/ssl_certificate.pem after adding --force to the above duplicity command.

At this point I don't know what to do. Is that error an acceptable one? The "Moving to a New Box" guide doesn't indicate one way or another, nor does it deal with the "already exists" folder error.

I suggest an improvement be made to the guide to clarify these issues. I would make my own pull request, however after the ssl_certificate.pem error -- I have no idea if that's an error safe to ignore, or what.

Same issue here...

[Alumniminium]

same issue here, just migrated to the 18.04 release.

runing sudo mailinabox afterwards gives me the following error

What do I do now...

Did you have files in use that it failed to overwrite from your backup?

lsof /home/user-data

I feel like i've experienced something like that back with 14.04 and a restore. I had to stop some services and run the duplicity commands from here: https://mailinabox.email/maintenance.html

[Alumniminium]

Those commands caused the problem to begin with. Yes, the same file as above, Error '[Errno 17] File exists' processing ssl/ssl_certificate.pem.

I've solved it by reinstalling the box, installing MIAB, copying everything from the ssl folder to a backup location, restore the backup from the 14.04 box, then put in the ssl folder I just backed up - back.

That worked.

I am also running into this issue.

then put in the ssl folder I just backed up - back.

Do you mean copying the contents into the new ssl folder? Or do you mean replacing the ssl folder?

@JoshData Could you take a look at this?

I now get an error when I visit the 'TLS (SSL) Certificates' page.

Edit: I had a custom.yaml in /home/user-data/www. It works now.

I replaced all SSL certificates from the backup by those from the clean install.

[codesxt]

I had the same problem. It was because I skipped the step:

sudo mv /home/user-data /tmp/user-data.empty

from this tutorial.

[vedevilolivedev]

I had the same problem. It was because I skipped the step:

sudo mv /home/user-data /tmp/user-data.empty

from this tutorial.

This step is absent from the current documentation under "Maintenance Guide" on the website.

For those unaware, there is now a separate mailinabox.email GitHub project.

Is the linked forum discussion for all migrations or just when upgrading from 14.04 to 18.04?
