I newly installed (again) Raspbian from Noobs and updated, upgraded and dist-upgraded. After all of this i reboot my Pi and tried to sudo su and got

Segmentation fault

error. Tried rebooting and re-installing OS but every time when i distro upgrade it's happening.

What's the matter my Pi ? I searched on board and google but i only get it's a SD Card problem but when i did not upgrade distro, i can install apache etc and reboot and no problem after it.

Is my SD Card corrupted or something wrong with distro upgrading ?

Note: My upgrading way is;

apt-get update
apt-get upgrade -y
apt-get dist-upgrade -y

BTW: I cant even sudo halt... it's giving me same error.

Edit: My /etc/apt/sources.list content

 deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi
 # Uncomment line below then 'apt-get update' to enable 'apt-get source'
 #deb-src http://archive.raspbian.org/raspbian/ jessie main contrib non-free rpi
  • It's really weird. Can you show us your /etc/apt/sources.list ?

The contents of your SD card is corrupt.

The only safe solution is to re-write the SD card from scratch.

Perhaps do a direct install of Raspbian Lite?

  • I already re-wrote multiple times and same error again and again. I'm not in an isolated network or something btw... What is the difference between Raspbian vs Raspbian Lite ?

  • @ahmetertem I have to assume you have a faulty SD card. Raspbian Lite uses a lot less SD card space. A lot of bloat has been removed. I don't know what though.

I formatted SD Card with SD Card Formatter and uploaded (wrote) via Win32DiskImager Raspbian Lite img and tried but same error. And I tried normal (not light) version too but still same error. Somehow my SD Card is corrupted.

I had same SD Card (same brand, same size) and tried Raspbian normal and it worked. I do not know still what is the exact problem but i know SD Cards can be corrupt.

  • Also formatted with sd card formatter and have the same symptoms. wget msg is just: "Speicherzugriffsfehler" Sep 23, 2019 at 17:01
