Client: Can't install on Ubuntu 16.04 (latest)

[ferdinandyb]

Expected behaviour

sudo apt-get install owncloud-client should install it (an upgrade removed it, that's why I even tried)

Actual behaviour

Does not install.

>> sudo apt-get install owncloud-client
owncloud-client : Depends: ocqt562-libqt5webkit5 but it is not going to be installed

>> sudo apt-get install ocqt562-libqt5webkit5
ocqt562-libqt5webkit5 : Depends: ocqt562-libqt5opengl5 but it is not installable

>> sudo apt-get install ocqt562-libqt5opengl5
Package ocqt562-libqt5opengl5 is not available, but is referred to by another package.

Same issue -- also commented in the Qt5 issue - has to do with that? #5470

[bytepan]

Same issue -- please fix it ASAP.
Thanks !

[m3asmi]

same issue

[tipichris]

Also on 14.04. An upgrade failed. A 'partial upgrade' to fix things removed owncloud-client. Can't reinstall.

The following packages have unmet dependencies. owncloud-client : Depends: ocqt562-libqt5webkit5 but it is not going to be installed

Attempting to install ocqt562-libqt5webkit5 gives
The following packages have unmet dependencies. ocqt562-libqt5webkit5 : Depends: ocqt562-libqt5opengl5 but it is not installable

So it's still there, but there are no sources for it.

[SamuAlfageme]

@priestoferis @Phlos @bytepan @m3asmi @tipichris we found some problems with the packages distribution and we're working on a fix.

On the meantime, you guys can try the alternative mirror in: https://download.owncloud.com/repositories/desktop/download

[Phlos]

Thanks @SamuAlfageme . That worked!

[ferdinandyb]

Following the instruction on the given page I got the following errors:

>> sudo apt-get install owncloud-client
Err:1 https://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Ubuntu_16.04  ocqt562-libqt5webkit5 5.6.2-1
Protocol "http" not supported or disabled in libcurl

As far as I know, this error can be fixed by changing the https to http, but I can't see where.

And error for installing the recommended package ocqt562-libqt5svg5

>> sudo apt-get install ocqt562-libqt5svg5
`E: Package 'ocqt562-libqt5svg5' has no installation candidate`

[SamuAlfageme]

@priestoferis if you properly replaced the repository URL in your /etc/apt/sources.list.d/owncloud.list, you should not be hitting https://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Ubuntu_16.04 still. Seems like openSUSE download servers are having some problems with their SSL configuration.

If you got an incomplete installation previously try wiping out those before reinstalling from the new mirrors:

# apt-get purge owncloud-client
# apt-get autoremove
# apt-get autoclean
# apt-get install owncloud-client

[ferdinandyb]

Ok, the issue was, that my original source list was owncloud-client.list while the above link's intstruction create an owncloud.list Thanks!

[ThroneNeNe]

Thanks！ That worked!

[jnweiger]

the rebuilds are ongoing. I expect the packages to be all back in ca 1h from now.

[jnweiger]

I've just tested the install on ubuntu 16.04 from the official repo st
https://software.opensuse.org//download.html?project=isv%3AownCloud%3Adesktop&package=owncloud-client

Works again, as before. Phew. Closing here. Please reopen, if it is not yet fixed for you (or anybody)

Sorry it still doesn't work.

[TimTim2017]

I tried it again just now and it seems to work. I was finally able to install owncloud-client on Mint 18.2 from the official repo without unmet dependencies.

[bytepan]

Solved, but I had to rename /etc/X11/Xsession.d/91ocqt562-qt5-opengl/90qt5-opengl to /etc/X11/Xsession.d/91ocqt562-qt5-opengl/90qt5-opengl.bak because it was giving error when installing ocqt562-libqt5gui5

dpkg: error processing archive /var/cache/apt/archives/ocqt562-libqt5gui5_5.6.2-1+22.1_amd64.deb (--unpack): trying to overwrite shared '/etc/X11/Xsession.d/91ocqt562-qt5-opengl/90qt5-opengl', which is different from other instances of package ocqt562-libqt5gui5:amd64

[smasherppk]

Does not work on ubuntu 17.04:
Redirection from https to 'http://ftp.gwdg.de/pub/opensuse/repositories/isv:/ownCloud:/desktop/Ubuntu_17.04/amd64/owncloud-client_2.3.3-8338_amd64.deb' is forbidden

[jnweiger]

@smasherppk
I am getting the same issue. Looks like the mirrors downgrade your nice https request to http, which is a bit silly, as ftp.gwdg.de can handle https:// perfectly well.

$ curl https://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Ubuntu_17.04/./amd64/owncloud-client_2.3.3-8338_amd64.deb
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

<hr>
<address>Apache/2.2.34 (Linux/SUSE) Server at download.opensuse.org Port 443</address>

As a workaround edit your /etc/apt/sources.list.d/owncloud-client.list either

• deb http://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Ubuntu_17.04/ /
  or
• deb https://ftp.gwdg.de/pub/opensuse/repositories/isv:/ownCloud:/desktop/Ubuntu_17.04/ /
  both work for me.

@dragotin is this something that should be fixed on the openSUSE side or on the ownCloud side?

[bee272]

Thanks jnweiger, using your http link and changing version to 16.04 solved the issue on my 16.04 as well.

[ernstki]

I think this issue needs to be reopened, because the "download" links from everywhere else on the web site point to the openSuSE site.

Which as of today still produces the errors described by the reporter.

There is also mention of this problem in the forums (which I'm going to go reply to in a minute, to point them here).

[ghost]

Probably solved anyway once https://github.com/owncloud/owncloud.org/pull/1277 is accepted / merged and the new links are published. So probably no need to re-open this.

[kemoc]

I have the same problem,
maybe this will help for devs
stack-curl-problem
i know there is about problem with cURL on windows but maybe we have the same pb on linux.

[michaelstingl]

OBS issue has been reported: https://bugzilla.opensuse.org/show_bug.cgi?id=1060231

[jnweiger]

Fixed by the friendly openSUSE admins as discussed in https://github.com/openSUSE/software-o-o/issues/123
Our downloads there should now work again!

[kemoc]

@jnweiger i confirm, on ubuntu 16.04 works, thanks.

[atanasantonov]

@SamuAlfageme Thank You!!!

[shaneonabike]

The solution by @SamuAlfageme was really the only solution that worked thanks so much bro!

[shaneonabike]

Sigh on another machine this is not working for me anymore :/

I'm getting

[jnweiger]

@shaneonabike do you have multiple repositories in the system?
It is a very frustrating message from apt to say 'is not going to be installed' for all the dependencies that should be installed. Can you try an explicit

apt-get install -f
apt-get install libowncloudsync0 

maybe that gives us a hint why it decides not to install the needed packages...

[shaneonabike]

I don't think so @jnweiger ... how would I determine that. Obviously Ubuntu would have it's own right?
When I tried your solution I get the same issue...

`The following information may help resolve the situation:

[jnweiger]

I am still stuck understanding the '.. but it is not going to be installed' part. For me it just means, that
something is in a bad state. I cannot reproduce the issue. Neither with fresh installs, nor with upgrades.

@shaneonabike @jdcrecur can you please post the output of

apt policy owncloud-client ocqt562-libqt5core5a

If anybody could send me a VM image with a broken install, I'd be more than happy to investigate.

Oh, I don't expect this to help, but: In case there are again broken mirrors out there, please also try explicitly choosing the same one that I get when testing:

cat /etc/apt/sources.list.d/owncloud-client.list
deb http://ftp.gwdg.de/pub/opensuse/repositories/isv:/ownCloud:/desktop/Ubuntu_16.10/ /

To get a clean restart, please to all of

apt purge owncloud-client
apt autoremove
apt autoclean
apt install -f
apt install owncloud-client

Furthermore, when I dig deeper it looks like it goes beyond libowncloudsync0. When I trace it down to the core problem I //believe// that it's related to no install candidate for libicu55 :/

Ouch! You are missing your main ubuntu repo.
libicu55 comes from http://archive.ubuntu.com/ubuntu/ xenial
Try

echo 'deb http://archive.ubuntu.com/ubuntu/ xenial main' >> /etc/apt/sources.list

And while beeing there, check if there are any trusty wily vivid remainders ...

[jnweiger]

@jdcrecur you are one ahead of @shaneonabike regarding libicu55.

[shaneonabike]

I was on Ubuntu 16.10 so I added that additional package which is _super halloween_ weird that it was not there. I checked and there are no other remaining strange packages. Also, adding that package does not seem to make the system aware of that package. Looking in synaptic I can see that there is a libicu57 but not a libicu55?

[jnweiger]

@shaneonabike there is confusion with 16.10 and 16.04 in your system.

. /etc/os-release
echo $VERSION_ID
echo $UBUNTU_CODENAME

search for everyhting in /etc/apt/sources.list and /etc/apt/sources.list.d/* that has a different version_id or a different codename.

[shaneonabike]

That! is so strange. But you were totally right and after I switched the owncloud it was happy as a clam. I apologize for all the false positive and I appreciate you helping me out @jnweiger

[jnweiger]

I guess, we can close here for now. This second round did not have much in common with the first round anyway.

[jdcrecur]

Any idea on how to fix the sqlite issue?

Depends: libsqlite3-0 (>= 3.12.0) but 3.11.0-1ubuntu1 is to be installed

[ghost]

@jdcrecur You're using the Ubuntu 16.10 repository:

500 http://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Ubuntu_16.10 Packages

but your base system is 16.04:

Depends: libsqlite3-0 (>= 3.12.0) but 3.11.0-1ubuntu1 is to be installed

https://packages.ubuntu.com/search?keywords=libsqlite3-0
https://packages.ubuntu.com/xenial/libsqlite3-0

If you add a 3rdparty repository to your system make sure that it is matching your OS.

[jdcrecur]

@kdslkdsaldsal
Thanks! Switching to 16.04 fixed the issue, i just assumed Linux Mint Cinnamon was based on the desktop distro of ubuntu. Thanks for the tip! It now works.

There must have been something recent that changed as on another linux mint machine half a year ago the install with the desktop owncloud-client apt repo worked from 16.10.

Thanks again!

Hi,
is it broken again?
I receive the same error on Linux Mint 18.1 Cinnamon 64-bit.

sudo apt-get install owncloud-client

I'm using this URL:

@tdeuling 2.1.1+dfsg-1ubuntu1.1 is something from upstream Ubuntu, not from owncloud.org..
Maybe check /etc/apt/sources.list and /etc/apt/sources.list.d/* ?

Mint 18.1 is a Ubuntu 16.04 variant. Trying the 17.10 repo is supposed to fail.

If really needed, you can try apt-get purge owncloud-client to uninstall the old 2.1.1+dfsg thing from upstream Ubuntu.

Yesterday I performed a distribution update. Now I'm running 18.3 and the current version of owncloud-client works well.
Version 2.1.1 wasn't new enough for communicating with Server version 10.0.6.

[guruz]

@tdeuling 2.1.1 is the one from the Mint/Ubuntu/idontknowwhat:-) repositories.
You need the client from ownCloud's repositories which are on download.opensuse.org (yes, confusing hostname, @jnweiger is working on changing that).

Also can't install. An AppImage or Snap would have been nice to avoid dependency problems for users with older distributions (same here).

We are working on an official AppImage
