I was attempting to upgrade the j-web package following an upgrade of EX4300s to 17.3. I was trying to remove the old package first, but ended up deleting the jweb-ex platform package Can the package be reinstalled, or will it still be present in the backup partition, that I coould then boot to?
If neither of those work and I need to reinstall JUNOS, can I just use request software add <package> where the package is the same 17.3 package I used when upgrading?
