How to fix Error building the cache: multimedia-libs.repo

Question

Trying to install playwright with npx playwright install i got the error

Host system is missing dependencies to run browsers. 
 Missing libraries: 

 libicudata.so.66
 libicui18n.so.66
 libicuuc.so.66  
 libwoff2dec.so.1.0.2
 libwebp.so.6        
 libenchant-2.so.2   
 libffi.so.7         
 libx264.so 

So tried

sudo zypper install -y \
     libicudata.so.66 \ 
     libicui18n.so.66 \ 
     libicuuc.so.66 \ 
     libwoff2dec.so.1.0.2 \
     libwebp.so.6 \ 
     libenchant-2.so.2 \
     libffi.so.7 \ 
     libx264.so

But this returned

Refreshing service 'openSUSE'.
Error building the cache:
[multimedia-libs.repo|https://download.opensuse.org/repositories/multimedia:/libs/openSUSE_Leap_15.3/] Failed to retrieve new repository metadata.

How to fix this so that zypper finds the matching multimedia-libs.repo?

Update

It seems the dependencies are needed for webkit (safari)

Answer 1

The output indicates this is a Tumbleweed system, but the multimedia:libs repository points to Leap 15.3, which is out of support since a long time, and as a result not available anymore.

While I can not tell what npx is and how it would determine if a particular dependency is satisfied or not, at least "x264" usually comes from the external Packman repository.

To search for a specific version use zypper search --details --provides --verbose --type package libicui18n.so, to use one of the strings mentioned above. I doubt "version 66" is still available.

Better ask in a way that makes it clear that the question is about "npx" rather than "openSUSE".
