New install 24.04: Thunderbird cannot send emails

  • 772

I have Ubuntu 22.04 still installed on one partition and I recently installed Ubuntu 24.04 on another partition.

  • I've been using Thunderbird happily for a long time, most recently version 115.13.0 on my Ubuntu 22.04 partition.
  • I installed Thunderbird on the new 24.04 partition too, version 128.0esr. It correctly reads my emails (through imap), but it cannot send emails, save drafts or mark emails as read on the server.

So Thunderbird 115 works perfectly but Thunderbird 128 doesn't on the same GMail account (same problem with another non-GMail account). I checked the smtp settings carefully, they are identical.

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

    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?

    To change from snap to Mozilla apt, I followed this but with one more step:

    1. First, add the PPA by Mozilla Team.

      sudo add-apt-repository ppa:mozillateam/ppa

    2. Then, copy and paste the following code in a terminal in one go (don't copy-paste line by line) to prioritize the apt version of thunderbird over the snap version.

      echo '
Package: *
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001

Package: thunderbird
Pin: version 2:1snap*
Pin-Priority: -1
' | sudo tee /etc/apt/preferences.d/thunderbird

    3. Next, remove the snap version of thunderbird.

      sudo snap remove thunderbird

    4. Remove the transitional package from apt (otherwise apt says the package is already installed):

      sudo apt remove thunderbird

    5. Install Thunderbird with apt.

      sudo apt install thunderbird

    6. To ensure that unattended upgrades do not reinstall the snap version of Thunderbird, enter the following command.

      echo 'Unattended-Upgrade::Allowed-Origins:: "LP-PPA-mozillateam:${distro_codename}";' | sudo tee /etc/apt/apt.conf.d/51unattended-upgrades-thunderbird
