Stuck at fsck "/dev/sda1: clean xxx/xxx files [...] " after upgrade to Ubuntu 16 from 14

Question

I've updated my Ubuntu distro, and since then everytime I boot the system I am stuck at the fsck screen

/dev/sda1: clean xxx/xxx files, xxx/xxx blocks

I`ve already trying accessing tty and installing xorg and/or nvidia drivers but keep getting the same error message from sudo apt-get install:

apt-get: relocation error: /usr/lib/x86_64-linux-gnu/libapt-pkg.so.5.0: symbol....

I had a GPU installed in my system at the time of the distro upgrade, but I've also tried a multitude of "fixes" with the GPU deactivated by the BOOT settings and none seem to work neither.

Can anyone help me with that? Thanks

Edit 1: Following the demand on a comment, I loged into recovery root and:

# sudo blkid 
/dev/sdb: PTUUID="000d2ed6" PTTYPE="dos"
/dev/sata1: UUID="6ad5e12f-8d6f-4659-b5d4-8fe9eb9d11df" TYPE="ext4" PARTUUID="c537cdcf-01"

# cat /etc/fstab/
# /etc/fstab: static file system information
# 
# Use 'blkid' to print the universally unique identifier for a 
# device; this may be used with a UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

Solution 1

I finally managed to fix my problem. It looks like it was caused by issues from PPA for Ubuntu toolchain. I downloaded (from tty terminal) the debian of package libstdc++6 for Xenial at http://packages.ubuntu.com/xenial/libstdc++6

In my case (amd64) I did the following (on tty, Cntrl + Alt + F1 on the "error" screen):

# wget http://security.ubuntu.com/ubuntu/pool/main/g/gcc-5/libstdc++6_5.4.0-6ubuntu1~16.04.4_amd64.deb
# dpkg -i libstdc++6_5.4.0-6ubuntu1~16.04.4_amd64.deb
# reboot

And voilà, that solved the problem :)

You'll also run into this exact error if you run out of disk space as well. I was stuck at boot

Ctrl + Alt + F1 or F2 into tty2 login

df -h says /dev/sda1 is 100% used

I find the stuff I need to delete with this command

du -d1 -h /home/username | sort -h

For example, I deleted some folders like so

sudo rm -rf /home/username/Desktop/folder/*
sudo rm -rf /home/username/.cache/*
sudo rm -rf /home/username/.mozilla/*

reboot and now it boots up no problem now

You need to run the following commands to install Intel graphics card drivers:

add-apt-repository -y ppa:oibaf/graphics-drivers
apt update
apt install xserver-xorg-video-intel

After that, run the below command:

sudo apt-get install ubuntu-desktop

Then: reboot

If you recently installed nvidia drivers, you might have disabled nouveau drivers. In my case I managed to fix this by removing every occurrence of nomodeset from /etc/default/grub file and then by executing sudo update-grub.

This was because nomodeset disables the use of any graphic driver. I disabled my nouveau drivers before installing nvidia ones.

Though this might not be the case with everyone.

If you can get to recovery mode from the GRUB menu, and go to root access, show me these commands... sudo blkid, cat /etc/fstab, free -h, and swapon. Edit that info into your question please. Start comments to me with @heynnema or I may miss them.

[Admin]

@heynnema edited the question with the data you asked for. Than you.

[Admin]

Thanks for the info. It all looks good, except that you've got no swap partition or /swapfile. That's not causing your current problem, but it's something that needs fixing. Please see my partial answer and we'll check your file system first. What is on sdb? Report back.

[Admin]

@heynnema I had some USB connections to a development board I was working on, I believe sdb is one of those.

[Admin]

Does it boot if you disconnect sdb? Let me know about the fsck.

[Boris Hamanov]

How did you figure that out? You should still create a swap partition or a /swapfile. You can accept your own answer to close the question.

As @heynnema mentioned, how did you realize libstdc++6 is the cause of the issue?

[GennSev]

I figured out that apt-get was not working, then I looked out for a fix (so that I could reinstall the video drivers), and ended out finding a forum post where someone mentioned that his computer was not booting because of the same problems I had on apt-get. Then I fixed it and everything is working fine again.

I've spend ~1h trying to fix stack fsck until I've found this answer. This is soo stupid.. Why just not say that the space is missing

I have been stuck at the stupid clean block screen for an hour now. Holy crap. I could buy you dinner, I GOT A DESKTOP!! WOOHOO!!! The problem was that all the answers are for Nvidia, this is the only one that supports intel integrated chips.
