I can't download new Plasma widgets and Plasma themes in Kubuntu 16.04 LTS

  • 772

Each time I try to download the new Plasma widget from the Plasma Add-On Installer, I get the following error: 

Loading of providers from file: http://download.kde.org/ocs/providers.xml failed

The same problem is also happening when I am trying to install new theme. Please check the below screenshot for clarification:

Any suggestions, comments or answers will always be appreciated. Thanks.

  1. I found about 20 files in /etc/xdg/ that all reference 

    ProvidersUrl=http://download.kde.org/ocs/providers.xml

    I think the download.kde server currently sends a redirect to 

    https://autoconfig.kde.org/ocs/providers.xml

    But I guess its not followed.

  2. I think this python code will help you out..

    import os

os.chdir("/etc/xdg")
file_list=os.listdir("/etc/xdg")

home=os.getenv("HOME")

os.mkdir(home+'/.kde/share/apps/providers')

provider="""<providers>
<provider>
<id>api.kde-look.org</id>
<location>https://api.kde-look.org/ocs/v1/</location>
<name>api.kde-look.org</name>
<termsofuse>https://api.kde-look.org/content/terms</termsofuse>
<register>https://api.kde-look.org/register</register>
<services>
<person ocsversion="1.6"/>
<content ocsversion="1.6"/>
</services>
</provider>
</providers>"""

prov=open(home+'/.kde/share/apps/providers/providers.xml', 'w')
prov.write(provider)
prov.close()

s_add="ProvidersUrl="+home+"/.kde/share/apps/providers.xml\n"

for i in range(len(file_list)):
    try:
    with open(file_list[i]) as t:

        new=""""""

        x=1
        for line in t:
            if "ProvidersUrl=http://download.kde.org/ocs/providers.xml" in line:
                new=new+s_add
                print file_list[i] + "====> is changed"

            else:
                new=new+line


    t.close()
    with open(file_list[i],'w') as f:
        f.write(new)

    f.close()
except IOError:
    pass

    And sorry if my code is bad!..Just did my best!!

  3. For me this worked:

    cd /etc/xdg
khotnewstuff4 plasmoids.knsrc

    I adapted this from here https://bugs.launchpad.net/ubuntu/+source/kde-runtime/+bug/1610665. The bug is also discussed here http://defrances.co/post/kdelook/.

  4. Type https://autoconfig.kde.org/ocs/providers.xml in browser.

    Copy contents.

    Create a providers.xml file and paste them into it.

    Go to /etc/xdg/

    Change this line 

    ProvidersUrl=http://download.kde.org/ocs/providers.xml

    to

    ProvidersUrl=file:///path/to/your/custom/xml/file/providers.xml

    in all the files that have it.

    I'm sure there is a single terminal command you can use to do that in all files, but I don't know what that is. Maybe someone can improve this answer. I suggest changing it on a single file first and testing the corresponding app first. The file that corresponds to the plasma add-on installer mentioned should have a pretty obviously fitting name.

    I found the info in this guide and followed it myself for a different error: https://bugs.launchpad.net/ubuntu/+source/kde-runtime/+bug/1610665

    I'm not sure why just changing the line to

    ProvidersUrl=https://autoconfig.kde.org/ocs/providers.xml

    wouldn't work. I can't test that, because I don't have the question's error.

    Or why the guide uses a local path url that doesn't seem to work on my end...I posted here what worked for me.
