The other day, after a do-release-update on an Ubuntu box I had some issues with a package which told me:
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)
here’s how I solved:
mv /var/lib/dpkg/info/BROKEN-PACKAGE.* /tmp/ dpkg --remove --force-remove-reinstreq BROKEN-PACKAGE
The accepted rule for backup best practices is the three-two-one rule. It can be summarized as: if you’re backing something up, you should have:
- At least three copies,
- In two different formats,
- with one of those copies off-site.
It may occur to some to have a bunch of old disks laying in closets and them suddenly having the need to attach them to a running machine to restore some old data. Or you could have the need to boot up it’s System.
How to know which OS X operating system is installed on that drive? Well, all you have to do is a simple:
over the Terminal.app. I’m writing this as a reminder for an eventual future need.
