From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Sorry, this is the output:

I'll try cleaning it better, but I already used a napkin.
mmc0: cannot verify signal voltage switchsuggests something is wrong with the hardware (either SD card or card reader).-110is a timeout error, and-123generally indicates a problem with media hardware.You're not gonna fix this with software. Try a different card reader, or if you think it's the SD card, put a bit of alcohol on a cotton swab and gently clean the contacts. Let the card fully dry, then try again.
Obviously this is a hail-merry shot, but your card is likely physically done for
I'll try cleaning it with alcol. Is it a good idea to use pressurized air?
Use isopropyl alcohol
Wouldn't hurt, yea
