Fresh install Ubuntu 24.04: thunderbird cannot send emails anymore

Hi,

I have been using Thunderbird happily for a long time, most recently version 115.13.0 on my Ubuntu 22.04 partition. Recently I installed Ubuntu 24.04 on another partition, including Thunderbird 128.0esr, now installed as a snap package (it's a recent change in Ubuntu; instead of apt package previously).

The new Thunderbird correctly reads my emails (imap) but it cannot send emails, save drafts or mark emails as read on the server. So I have Thunderbird 115 on the old partition working perfectly, but Thunderbird 128 not working on the same GMail account (I also have the same problem with another non-GMail account). I checked the smtp settings carefully, they are identical between the two versions.

It's possible I made a mistake, but I'm at a loss about what is wrong. How can I diagnose and solve this problem?

(I know that I could reinstall Thunderbird with the apt package, but I assume that the snap package should work too and I would like to understand the cause)

I'd be grateful for any advice

In case anybody is interested, I ended up removing the Thunderbird snap package and installing the Mozilla apt package. This installed Thunderbird 115.13.0 in 24.04, it solved the issue.

I'm disappointed that I didn't find any better solution: after all, isn't the snap version of Thunderbird supposed to be able to send emails too?

I think what you need to understand is snap packages are sand boxed. There might be something wrong with the snap package used for Thunderbird that is does not explain itself to the sandbox correctly, But basically every snap package runs in a sandbox environment and the one used for Thunderbird is limited to what it can access.

I do not pretend to understand this snap stuff, but perhaps file a bug report as apparently the Development team have something to do with the packaging of the snaps.

Thank you Matt for your answer,

I'm aware that snap packages are sandboxed, but this does not explain why the snap version was unable to send emails. So there must have been some other issue, but it's fine: in the end the non-snap version works, that's all I need :)
