Thunderbird - I have to restart networkmanager every time

TySpicer · 2025-12-18 16:49:36

Another update: I don't know if it matters, but here are some more debug lines. I used my workaround (restarting Thunderbird) to send a message, and it printed this after successfully sending an email:

console.debug: mailnews.smtp: "Message sent successfully."
console.debug: mailnews.smtp: "C: QUIT"
console.debug: mailnews.smtp: "S: 221 2.0.0 Service closing transmission channel\r\n"
console.error: mailnews.smtp: "NetworkError: a Network error occurred"
console.debug: mailnews.smtp: "Socket closed."

For clarification, this still happens despite you're now booting w/ "ipv6.disable=1"

cat /proc/cmdline

It's been a while, since I looked at this, I'll take a look.

I booted back into Mint, went to `/etc/default/grub`, and found these two lines:

GRUB_CMDLINE_LINUX_DEFAULT=...
GRUB_CMDLINE_LINUX=...

They both had `ipv6.disable=1` in them. In the wiki article, I saw I could also try `ipv6.disable_ipv6=1`, so I tried that in both lines instead.

I ran `sudo grub-mkconfig -o /boot/grub/grub.cfg` and `sudo update-grub`, then booted back into Arch.

I ran `cat /proc/cmdline`:

BOOT_IMAGE=/boot/vmlinuz-linux root=/dev/sda8

Lastly, Thunderbird still seems to be broken, but the workaround still works.

BOOT_IMAGE=/boot/vmlinuz-linux root=/dev/sda8

Means IPv6 isn't disabled - if you don't manage to get control over Mint's grub config, try https://wiki.archlinux.org/title/IPv6#sysctl

TySpicer · 2025-12-20 19:28:11

Well, it seems Mint is broken now. I could get to the login screen, but after typing in my password, I just got a black screen. I could move my mouse around, but nothing else happened. How do I get back into Mint from here?

This sounds like your Mind DE (cinnamon?) broke, but I can't really tell why nor is this the place to fix it.
You should™ be able to use switch the VT (ctrl+alt+f3), login there and check the system journal on what went wrong w/ starting your GUI DE (you'll likely see some crashes and/or this might be a problem w/ the cinnamon compositor not rendering anything)

TySpicer · 2025-12-21 17:28:36

I fixed Mint! It was actually pretty simple, I just had to change `ipv6.disable_ipv6=1` back to `ipv6.disable=1`. I was able to do this from the boot menu parameters, then I updated the file itself so it's permanent.

With this discovery, I wonder if making these changes from Mint will have any impact on Arch at all. Maybe I should be looking for files on Arch instead of Mint?

I checked `/etc/sysctl.d/` on Mint, and there's no `40-ipv6.conf` there. There is a `10-ipv6-privacy.conf`, would this be relevant? Should I create `40-ipv6.conf`?

I'll double-check all this on Arch, as well.

TySpicer · 2025-12-21 17:43:24

Welp, I might have actually figured it all out! For some reason, the boot loader name for Arch changed, so I went back into Mint, opened Grub Customizer, and changed the name back to just "Arch". While I was there, I saw a menu that looked a lot like the boot parameters menu I had seen in the boot loader. I added `ipv6.disable=1` to the `linux` line. After booting into Arch, here's the output of `cat /proc/cmdline`:

BOOT_IMAGE=/boot/vmlinuz-linux-lts root=/dev/sda8 ipv6.disable=1

Success? I'll have to see if Thunderbird works consistently over the next few days, but I guess I finally disabled IPv6, at least.

Update: As I was about to post this, I did another Thunderbird test, and it failed again. Did I miss something?

seth · 2025-12-21 20:13:01

This contrasts with your earlier findings, https://bbs.archlinux.org/viewtopic.php … 2#p2265502
Please post your complete system journal for the boot after the failure:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Btw. is *only* thunderbird affected, your browser etc. still work fine?

TySpicer · 2025-12-22 18:58:42

https://0x0.st/Pzod.txt

Yes, everything else is working fine. It's just Thunderbird that fails to send emails, unless I restart it.

And *just* restarting thunderbird doesn't help?

the same NM process ran for almost a day and reconnected a could of times (related to system sleeps)
At which point did thunderbird fail?

Also, it seems this is only for my school (.edu) emails. My personal email (@gmail.com) works fine.

What's most likely the case is that your school account severs the connection, is it imap? Imap idle? Try to raise the beacon frequency.

I doubt this is a network issue at all.

Restarting Thunderbird fixes the issue, usually for only one message.

seth wrote:

I should have been more clear about the journal. I did another test and wrote down some approximate times. Here's a new journal: http://0x0.st/PzHX.txt

And here are the relevant times:

13:16:16 - Attempted and failed to send an email
13:16:33 - Restarted Thunderbird
13:16:49 - Successfully sent an email

Predominantly your email account settings, whether the server supports imap idle and thunderbird tells you that idk, but you can query it w/ openssl.

(echo "? CAPABILITY"; sleep 3) | openssl s_client -crlf -connect imap.gmail.com:993 |& grep CAPABILITY

The sleep in there will keep the connection open so the server has a chance to respond and this queries gmail, you'll have to replace server and in doubt also the port.

Where can I change this?

The mail settings, I presume.
Idk whether thunderbird allows you to configure this but apparently it was at one point called push emails, https://superuser.com/questions/1066596 … ifications
