- How To Fix No Packages Were Eligible For Install
During the installation of OS X El Capitan on my Mac Book Pro, the install fails and I am left with 'OS X Could not be installed on your computer File System verify or repair failed. Quit the installer to restart your computer and try again.' No matter how many restarts I do it does not install. Also repair does not work in disk utility. Restart and Reinstall Mac. Sometimes, the simplest of the solutions can fix even the most critical. Homebrew complements macOS (or your Linux system). Install your RubyGems with gem and their dependencies with brew. “To install, drag this icon” no more. Homebrew Cask installs macOS apps, fonts and plugins and other non-open source software. $ brew install -cask firefox. Making a cask is as simple as creating a formula.
Os X Could Not Be Installed No Packages Were Eligible
Because one package cannot be installed, no packages are installed and the update fails. The following techniques can provide more information about why the ubjavavm-incorporation package cannot be installed: Use -v options. For example, use -v or -vv to receive more verbose output. Specify a package to update. This approach is going to build and install wget in Mac OS X from source, this means you’ll need Xcode (App Store link), or at least and the Unix command line dev tools installed on the Mac, but it has the benefit of eliminating the need of a package manager like Homebrew or MacPorts.

A key step for upgrading the disk on a MacBook Pro is to install a new operating system on the new drive, and then use Migration Assistant to copy over the old data. Depending on how you went about the work, installing Mac OS X on the new system may give you a message: OS X could not be installed on your computer. No packages were eligible for install.
This is what it looks like in the installer. Upon seeing this I went 'HUH?' because the installation was from a thumb drive I'd used many times to install Mac OS X (El Capitan) successfully.
The above image came from an attempt to install El Capitan. I just got the following message, macOS could not be installed on your computer, while trying to install macOS High Sierra.
In both cases there was the same cause. In the El Capitan case, as I say in the next paragraph, the hardware clock had reset to zero because it did not have a battery pack. In the High Sierra case, I had performed a hardware reset of the computer in an attempt to fix a bootup problem. I had found advice to disconnect the battery, the power supply, then hold down the power key for a few moments. In both cases the hardware clock had been reset to zero, and macOS refused to boot.
After some yahoogling (duckduckgoing) I came across a simple solution. This particular computer had been running with no battery, and therefore the hardware clock was reset to zero, and Mac OS X had a test against that condition.
We've discussed elsewhere the process to install Mac OS X onto a computer, and transfer information from an old drive. It's during that process when the above message appears. A couple steps prior is where you can take action to correct the problem.
At this step, click on Terminal ...
Then change the operating system date.
When running this particular Terminal session, you are ROOT meaning you can change anything on the computer. Normally we type 'date' at the command line just to find out the current day/month/year/time. But, the date command can be used to change the time registered in the system clock.
As I said above, for this particular computer the system clock had been reset to zero because the battery pack had been changed. In fact, the computer had run without a battery for many months because the old battery had gone bad.
As you see on the screen, the date had been January 1, 2001. I then changed the system date to the current time as of the writing of this posting.
To understand the second command, go to a terminal window and type 'man date'.
In the synopsis section you'll see this as an option for the 'date' command:
That's a little obtuse, but further down the manpage is this key:
In other words, the date code for this purpose is month-day-hour-minutes-year ... hence, that's what I entered and it changed the system date to match.
Afterward I closed the Terminal window and was able to successfully install Mac OS X on the computer.
