          @jdaviescoates How is working now? Did you experienced problems in last days? I switched to Wasabi meanwhile find a durable solution to this problem...

            @p44 I'm not having any problems. Streaming music off of my Hetzner Storage Box mounted as a Cloudron Volume and connected to my Navidrome app as I type.

              If I am reading those version messages correctly, it does look like the automount on Ubuntu 20 has some kind of regression, while servers on 18 are working reliably?

                In plain english 🙂 yes the issue seams to be only with Ubuntu 20.04

                  Possible related to this?

                  SMB1 disabled by default: can still be enabled via a /etc/samba/smb.conf config change;

                    thank for your reach, I'll definitely give a try to this and come back soon.

                      @jdaviescoates I just look at it
                      and on Cloudron Samba server is not installed
                      so nothing to configure in /etc/samba/* which actually don't even exist.

                      WEBDAV

                      I have the same behavior with webdav
                      on reboot I have to login and do mount -a

                      here the option for my davfs in /etc/fstab: rw,_netdev,uid=yellowtent,gid=yellowtent,file_mode=0660,dir_mode=0770 0 0
                      I also tried with auto and defaults

                      few people suggest to use rc.local

                        I just got an idea
                        @nebulon
                        it is possible than cloudron mount the volumes before my automount so then the target directory of my automount is not empty ?

                        Also how could I destroy thoses volumes the GUI don't make it happen ?

                          nope, even without any volumes configured in Cloudron
                          CIFS and WEBDAV won't mount automatically 😞

                            @nebulon and @girish

                            I just copy the config (/etc/fstab and /etc/davfs2/secret) to my Ubuntu 20.04LTS Desktop
                            and my webdav mount automatically on the reboot.

                            So it seams to be a bug on the cloudron side.

                              Cloudron itself does not handle any mount points as such. So this looks like this is some issue with 20.04 server then. Note that the desktop flavor has a lot more things installed usually, which may or may not trigger automounting correctly.

                                I have no doubt of the quality of coding from the Cloudron Team
                                but I just boot an ubuntu 20.04 LTS at Hetzner
                                did

                                apt update
                                apt install -y davfs2
                                mkdir /mnt/storagebox
                                

                                than cut and past my 2 lines
                                1 from /etc/fstab
                                1 for /etc/davfs2/secret

                                reboot and it work

                                so yes Ubuntu Desktop have probably more fuse than server but now the only difference is Cloudron.

                                  thanks for testing, so then probably one of the dependencies we install, somehow changes either the init order or even disables some bits there. Looks like we have to debug this further then on fresh installations to get some more information what systemd does differently in both scenarios.

                                    I'll run an fresh install of Cloudron than install davfs2 just to be sure

                                      so boot up a new instance Ubuntu 20.04 LTS @Hetzner
                                      ran

                                      wget https://cloudron.io/cloudron-setup
                                      chmod +x ./cloudron-setup
                                      ./cloudron-setup
                                      

                                      reboot than install davfs2 apt install -y davfs2
                                      and configure /etc/fstab and /etc/davfs2/secrets
                                      reboot

                                      it don't mount automatically
                                      but mount without issue with mount -a

                                        @jodumont I was able to reproduce this now also outside of hetzner on 20.04...not yet sure why and what causes the difference

                                          To give some update, this is DNS related and how the init sequence works on 20.04 now.
                                          Problem is at the point when systemd decides to attempt to mount the remote filesystems, unbound, the dns resolver is not yet started. This means the remote fs cannot be mounted.

                                          There are currently two workarounds:

                                          1. Instead of using the DNS name in the fstab entry, just use the IP
                                          2. add x-systemd.automount as an additional argument for the mountpoint in the fstab entry

                                          Ideally we find a better flow by tweaking some of the init order in the future.

                                          For now I've added that option requirement at https://docs.cloudron.io/backups/#cifs

                                            @nebulon what about a retry after the initial failure after unbound loads?

                                            maybe add a mount -a at the end of the unbound script?
