Hello, does Cloudron have the ability to make a backup using the Webdav protocol?
I have a Nextcloud (Hetzner STORAGE SHARE) with a lot of space. And I would like the claudron to download backups to it.
I did not find such an opportunity in the settings.

@girish Hi, I have the same problem with "perpetual update". I also have a Hetzner Ubuntu 20.04 machine. (But I upgraded Ubuntu according to the instructions from 18>>20 , almost a year ago.)

I used the dpkg --configure -a command. and that seems to have fixed the problem. (hope so )

you should continue anyway. Otherwise, you should install GRUB somewhere.

@girish Hello, unfortunately the update did not bring any improvements.
If this information helps, then the latest version on which the gems worked properly is, "Package Version org.redmine.coudronapp@1.6.2 ".

I have suspicions. that the problem might be with the Ruby version.
Because the latest working version of Redmine is installed with the Ruby version: "ruby 2.5.1". And the problems with gems started with the version: "ruby 2.7.0"

@girish I noticed that the path has changed in the new version.

Hi! The latest version of Redmine is working!
A clean install works as it should!
Updating Redmine from 1.6 to 1.9 also works. The only thing I had to manually delete the "Bundle" folder And after that everything worked as it should.

Thank you for your hard work!

@girish Hi, I also tried to change Ruby version via brightbox to 2.6. But after every reboot of the application, Ruby reverts to version 2.7.0.

@girish Hello! Are there improvements in the bug fixes?
The Redmine website states that Ruby 2.7 is not supported. Need to use Ruby 2.7.2 or higher.
(Redmine 4.2 does not support Ruby 2.7.0 and 2.7.1. Use Ruby 2.7.2 or higher )

@girish Hello again, how are the redmine updates progressing?

@girish Hello, how is the update going? Is there an improvement in installing gems correctly?

@girish Ok, Thanks!

@girish Hello, I saw that a new version of Redmine 4.2.2 (2021-08-01) has been released.
Perhaps updating to the latest package will help fix the problem with the gems.
