Cannot open Eclipse Marketplace Cannot install remote marketplace locations: Cannot resolve host

Question

I am using eclipse Kepler version and trying to install Sonar plugin from Eclipse marketplace. But I am getting below error

Cannot open Eclipse Market

Answer 1

Try to add the host like this: marketplace.eclipse.org/catalogs/api* in Proxy bypass.

Answer 2

For me I solved the problem by those steps:

1. Use the CNTLM proxy, which can be installed and run by following this GitHub readme file.

2. Go to-Window->Preferences->General->Network Connections

3. Click on an empty line and add a host and the same port that youn configured in CNTLM

Answer 3

I encountered the same today morning on Ubuntu 20.04LTS with Eclipse Version: 2020-03 (4.15.0). This is what worked for me.

sudo vim /etc/resolve.conf

And add these 2 lines.

nameserver 8.8.8.8
nameserver 8.8.4.4

Save the file and restart the network. It worked like a charm.
