Upgrading to 10 is not recommended yet for production systems, so the stable packages yet direct to 9.1.5, until we release 10.0.1 in a few weeks. You can use the 10.0.0 packages directly, though, via this link: https://download.owncloud.org/download/repositories/10.0/owncloud/
I'm unsure why it tries to download Version 10 from the stable repo. As I remember I never changed the configuration of release channels, so why does it try to get this version?
P.S.: I dont want to upgrade, but apt provides this version.
I'm having the same issue on the Raspberry Pi version of Ubuntu 16.04 LTS. It must be something screwie going on with the Owncloud update repos.
My biggest concern is that I can't seem to update anything else on my server whilst having this problem with the owncloud repo. I have python, systemd, udev, and several other updates available, and none of them will happen while I'm getting this error from owncloud.
If this is a productive environment please wait for the release of 10.0.1 or 10.0.2 before doing any upgrades as advised in [1]. Until that time they probably have fixed the repositories. You can also switch to the 9.1 repositories [2] which still gives you updates for your current 9.1.x
Disclaimer: for production systems we recommend to wait for the first update release. it is to be expected in about 4 weeks.
Nice to know that we should wait ... it was in the stable repo for centos7 so a normal yum update upgraded it, and then I needed php56, which is not in the normal centos repo.
Problems is solved now, but it seams it should not be in the stable repo yet.
Yes, most people came to the same conclusion. A first version of a major release was never pushed directly to the "stable" repository in the past so this was probably a mistake (The 10.0.0 release was rolled back from that repo a few hours later).
I had this crazy thing happening, I have 2 owncloud servers. I did an update it one, and successfully upgraded to 10.0.0, days latter I tried to do the upgrade on the other server and there was no new releases... I came back to the first server checked the version at the repository, and was the 9.1.6.
I read that they pushed the 10 to the repositories by mistake and they took it out. I'm not in a rush to upgrade. But I'm sort of scared that they are thinking about making owncloud under pay license. That will be bummer since I love the project, and I use it for my personal stuff. I participate on the translation to Spanish like a lot. I'll just keep waiting until the 10.0.1 or .2 stable is at the repository (hopefully)
Maybe the apt-cache is broken? I would try to remove the repository from the apt config, run apt-get update, re-add the repositories again and then run apt-get update once more.
