For the record, I hit that issue too. /boot got full. However, I could not fix it with the solution at https://forum.cloudron.io/topic/1310/disk-filled-up-with-kernel-update-artifacts/2 . I had to follow https://askubuntu.com/a/430944 (slightly adapted)

@nebulon said in Disk filled up with kernel update artifacts:

rm -rf /var/tmp/mkinitramfs*

I had to instead do:

cd /var/tmp find . -type f -delete -print

This was running for like 5 hours! (and still running)

In another server instance hit by https://forum.cloudron.io/topic/1382/error-for-multiple-apps/12, recreating docker containers did not help. I even disabled apparmor altogether using sudo systemctl stop apparmor and sudo systemctl disable apparmor. We tried server restart as well and that didn't help either.

After disabling apparmor, I saw that mysqld would just quit without showing any error message or log output 😞 As a final thing, I just ended up moving platformdata/mysql to mysql-old and recreated containers again. That made mysql come up and then we restored all the apps.

Still a bit crazy/worrying that we hit this bug atleast twice now and there is no clear resolution.

For others reading this, currently the process of giving build service access is not automated. If you need access, please send us an email to support@cloudron.io.

@rtyu1120 for hackmd there is already some progress https://forum.cloudron.io/topic/1222/hackmd-fast-and-flexible-real-time-collaborative-markdown/10

@girish I also realized that the mysqldump for the TT-RSS app is huge (679 MB in my case). Could you implement some compession in the database dumps (and use PostgreSQL as recommended by the author)?

@uiharu Ah, thanks!

Ah my bad, for whatever reason I deleted the DNS entry and didn't check what was up, all my fault :s

@girish working. thanks!

Thanks again! Everything is up and running now!

@scooke Right, so the newapp.app@domain.com is the default allocated mailbox. If you want to make the app use a different email address, you have to do this https://cloudron.io/documentation/email/#changing-the-from-address-of-an-app . It's geeky, we are looking into fixing this in the next release since this is often requested.

Awesome. Thanks!

@fbartels @girish Thank you for the support.

Solution:

use a SMTP mail solution sendmail (and the mail()) are not usable in current state PHPMailer could be used as an alternative

@girish Okay, workaround works ! 🙂

@seeker said in Testing Ensuring Email & Mailtrain is set up Properly:

Installed the app. It looks lie mailtrain creates an admin email that is <install name.app.domain> That email address is also used by campaign defaults. I tried sending a test email to it however and it did not go anywhere. In testing sending some emails, it does not appear can just change this email to anything you want. It must match the app domain???

By default, an app is allocated a "mailbox". It can only send email as that mailbox name. This is a security policy. You can change the mailbox name by following https://cloudron.io/documentation/email/#changing-the-from-address-of-an-app

Below you will see that the Blacklist:4 and Failed:2

The results are entirely based on the IP of your server and which VPS provider you got your server from. In fact, many providers like Amazon EC2, Google Compute don't let you send emails at all. I would recommend setting up a relay via Mailgun, Postmark or similar. It is the best way to ensure delivery of mail.

mail-tester

mail-tester runs your email via SpamAssassin. So make sure you send email to it with some real text! If you send fake text or empty emails, it will correctly mark your email as spam. I will put this note in our docs as well.

@nebulon thank you very much! Missed that the config.php is symlinked to /app/data and therefore it is editable 👍🏼

Upon some investigating, did find a polls utility like doodle in nextcloud. It allows you to share it with users but also share a public link. Pols can be text based or created using a calendar. Persons responding can answer a yes,no and maybe on whatever options are offered.

@TheNils For new domains, the NS record sometimes takes to propagate. That error message means that it's not propagated to the Cloudron server yet. You can try this:

SSH into the Cloudron host -t NS mydomaine.net (This should not display NXDOMAIN) If the above works, it should work on Cloudron as well. If not, can try sudo systemctl restart unbound and then try adding the domain again?

We will improve the error message to be more descriptive (https://git.cloudron.io/cloudron/box/issues/548).

@nebulon Thank you 🙂
