Update v 70 >> 71 Script fails on Duplicity, arm64

Help with Setup/Upgrade
1

Please advise how to skip the duplicity update since it fails with my snap version.
Please note that I use a snap version of duplicity since I ran my MIAB on arm64 instance and there is no arm64 latest version of duplicity, thus the update fails:

I deleted it
sudo rm -rf /bin/duplicity

I linked it to snap afterwards but update fails
sudo ln -s /snap/bin/duplicity /bin/duplicity

Can I edit the setup script and skip the duplicity part?

This is the message:

Does it help to hold the duplicity package? E.g. sudo apt-mark hold duplicity

No.
And I don’t see any duplicity interventions in the changelog mailinabox/CHANGELOG.md at v71 · mail-in-a-box/mailinabox · GitHub

@JoshData How can I skip the duplicity version check error as per above to achieve successful upgrade on arm64?

Here is the newest error message:

I’m sorry I just don’t support things that I’ve said isn’t supported by the project.

5

That’s a pity since arm64 instances have much lower carbon footprint.

6

Please don’t imply that I owe anyone my personal time beyond what I’ve stated that the project is committed to. If it’s such a pity to you, you can put in the effort yourself to figure it out.

Try this:

After this status page shows v 70. What does it say on your status page?

Not running arm, but I have an exclude file for the duplicity package. I got an error at the very end of the MiaB update process but I’m now showing as running 71a.

Exclude duplicity like so:

sudo echo -e "# Duplicity is installed via snap\nPackage: duplicity\nPin: release *\nPin-Priority: -1" > /etc/apt/preferences.d/duplicity

Thanks: But I cannot get rid of this. Now I cannot install the old version as well:

ubuntu@box:~$ sudo apt install duplicity
Reading package lists... Done
Building dependency tree... Done

Mine shows V71. But it looks like V71a is out now. I would try again with the new script. Then follow the steps in the fix if the error happens again.
Good luck!

Well, yes. That’s the idea. Installing duplicity via apt will not work because it’s been prevented from installation by the preferences file. If you would like to re-enable it for installation via apt, just remove the /etc/apt/preferences.d/duplicity file.

OK that did the job. Thanks @mokiejovis
So I removed the duplicity file. Reinstalled apt duplicity >> sudo apt install duplicity I got:

sudo duplicity --version
duplicity 0.8.21

Update 70 >> 71 just ran sudo mailinabox
It completed OK
Then, curl -s https://mailinabox.email/setup.sh | sudo -E bash
Update 71 >> 71a
Completed OK
Then, I did the snap hack from above


sudo snap install duplicity --classic --edge sudo ln -s /snap/bin/duplicity /bin/duplicity

duplicity --version
gpg: WARNING: unsafe ownership on homedir '/home/ubuntu/.gnupg'
duplicity 3.0.3.2 November 25, 2024

After this, for each update just:

sudo rm -rf /bin/duplicity
sudo ln -s /snap/bin/duplicity /bin/duplicity

Thanks!!

Hi there. Is it necessary to revert duplicity to the apt version before updating to v71a, and then reinstall the snap version? Thanks

I don’t do purge and remove. It stays installed.
After update just:

sudo rm -rf /bin/duplicity
sudo ln -s /snap/bin/duplicity /bin/duplicity

Hi there. Thanks for that. I re-ran the upgrade to 71a, then immediately ran the commands above. Manually instigated a backup, no errors were reported, checked backups & confirmed there was a newly created file. So appears to be all good. I appreciate the guidance.
