Sorry guys but I have not had time to go through the log, yet. But the problem happened again: Building repository 'Packman Repository' cache .....................................................................................................................[done] File '/repodata/repomd.xml' not found on medium 'http://download.opensuse.org/distribution/leap/42.3/repo/oss/' Abort, retry, ignore? [a/r/i/...? shows all options] (a): i Do you want to disable the repository openSUSE-42.3-0 permanently? [yes/no] (no): no Warning: Skipping repository 'openSUSE-42.3-0' because of the above error. File '/repodata/repomd.xml' not found on medium 'http://download.opensuse.org/distribution/leap/42.3/repo/non-oss/' Abort, retry, ignore? [a/r/i/...? shows all options] (a): i Do you want to disable the repository openSUSE-Leap-42.3-Non-Oss permanently? [yes/no] (no): no Warning: Skipping repository 'openSUSE-Leap-42.3-Non-Oss' because of the above error. And one extra thing. The WiFi connection requires a proxy authentication i.e., there is a web page at which I have to login before making any connection. So I think the repos refresh is going on before I am logged in.
