Connecting plugin via snap now causes certbot to crash

[RedChops]

I've been using this plugin for quite some time now, and as of some recent update having it connected causes certbot to crash with the following error message:

An unexpected error occurred:
pkg_resources.ContextualVersionConflict: (cryptography 38.0.1 (/snap/certbot/2414/lib/python3.8/site-packages), Requirement.parse('cryptography<38,>=0.6'), {'msal'})
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /tmp/certbot-log-_bnwfto2/log or re-run Certbot with -v for more details.

I confirmed that this is being caused via this plugin, since removing it allows certbot to run again.

It looks like the snap container just needs to be rebuild most likely. Certbot now uses cryptography 38, and the snap package for this plugin looks like it just has an old version of an azure library bundled in

Is there a workaround for this, i am having the same issue

[cpressland]

Unfortunately @terrycain is somewhat indisposed right now and I don’t have access to the Snap Store to patch this. I have asked him for this but it’ll happen later this week.

For the moment, downgrading certbot is one solution, not great, not terrible.

I ran into this issue myself and build a hacked version of certbot-dns-azure to fix it. I've submitted my changes in PR #24; if you need it in a hurry, like I did, you can grab those and build from there.

(Or, if you trust me, you can always grab my build here

certbot-dns-azure_1.5.0_amd64.snap.gz

and install it with sudo snap install --dangerous certbot-dns-azure_1.5.0_amd64.snap until the new official version is ready.)

Thanks @cerebrate, working perfectly now. :)

For those preferring to downgrade, here are the commands I used to show available versions and revert to the previous (1.30.0), which fixed the issue: snap list certbot --all snap revert certbot

[sirsnork]

Any news here? I can't seem to get cerebrate's version it show under 'certbot plugins' at all obviously the old version is broken. Downgrading doesn't seem to be an option either as it only lists 1.31.0 on my installs

[cerebrate]

@sirsnork Just to check, is it showing up under snap connections?

Interface           Plug            Slot                       Notes
content[certbot-1]  certbot:plugin  certbot-dns-azure:certbot  manual

If not, you may need to connect it manually for it to show up.

[sirsnork]

@cerebrate No, nothing is returned from that command.

certbot plugins shows the 4 base plugins only. It is "installed" under /snap, ie the files are there in a folder called certbot-dns-azure, uninstalling removes it ok and running the install commands creates that folder again (so it's not the old plugin version that's there)

[cerebrate]

snap connect certbot:plugin certbot-dns-azure:certbot should be what you need, then.

[sirsnork]

@cerebrate Legend! All good now!

Sorry lads, was in the middle of moving house. I've promoted 2.0.1 to latest/edge, can someone give that a test for me?

[m4rkglenn]

Thanks Terry!

I have tested this and is now working as expected.

Great thanks :) I'll promote it to the latest/stable branch on the weekend if I get no issues with it until then
