Run sudo mkdir /mnt/tmp

Then again:sudo arch-chroot /mnt

[root@EndeavourOS liveuser]# sudo mkdir /mnt/tmp
[root@EndeavourOS liveuser]# sudo arch-chroot /mnt
/bin/bash: error while loading shared libraries: cannot open shared object file: No such file or directory

I have to admit that this is getting a bit over my head.

Your system looks to be broken in a way that I feel I am not able to troubleshoot further.

If no other suggestions comes in from other users, you might be better off backing up your personal data under your home directory plus .connfig folder and also .mozilla if you use Firefox and reinstall the system.

can you possibly translate these commands to arch commands? this is from ask ubuntu. seems i can potentially install that package for

The file you need, /lib/x86_64-linux-gnu/ is provided by the package libreadline7, not by any version of libreadline-dev. There’s no such package as libreadline7-dev in any Ubuntu distribution.

Since you have and its friends, you’re probably using Ubuntu 16.04 or 14.04. The libreadline7 package is available in Ubuntu 18.04. So, the straightforward answer here is that you can get it by upgrading to or installing 18.04. To check, you’d then run

apt policy libreadline7

and if it’s not installed, run

sudo apt update
sudo apt install libreadline7

There’s a really dirty hack (not recommended, but not very dangerous) you could try if you just want to get past this step to see if you’re going to hit another issue before you commit to upgrading, or you really can’t upgrade right now. This is to make a symlink pointing to the older version of the library, so that the program thinks it’s using and is actually using

sudo ln -s /lib/x86_64-linux-gnu/ /lib/x86_64-linux-gnu/

This might possibly make the program run. But it might also crash mysteriously without any meaningful error messages. If you leave the symlink like this, other programs you install from third party sources might also fail to report the missing dependency and crash mysteriously. You might forget what you did and wonder what is wrong with your silly system, so it’s better only to try things like this for testing. You can always just delete the symlink to get back where you started.

I’m sorry. I have no idea what that shared library is for and how to fix it.

would you know how to translate those commands from ubuntu to arch, so that i may try them? at this point i might as well try that dirty hack and see what happens before i reinstall eos tomorrow… i just dont know how theyre entered in eos. for example what command in arch is this apt in ubuntu?

The only thing I can think of, if that file is missing is that to download the package that provides it, extract it. Locate the file and copy it to its proper location in your installed system.

This might be a long shot but it is the best I got.

This won’t assure either that the chroot issue may be solved. Could be chasing down the rabbit hole.

I’m afraid, I’m going to log out. Perhaps some one could pick up from here. Good luck!

Package readline should be installed by default.

Just guessing that it may be corrupted, so reinstalling readline might help. But that might not be the only corrupted package…

How could OP do that when attempting to arch-chroot fails and throws the error about that missing library?

Not sure if pacman --sysroot /mnt from the Live USB can do that either since it needs to set up a chroot as well.


Specify an alternative system root. Pacman will chroot and chdir into the system root prior to running. This allows mounted guest systems to be properly operated on.

Does mounting work? Then copying package file might work…

Edit: typo: filefiles

Doesn’t this have to have /boot in the line somewhere? :thinking:

No, on EnOS with systemd-boot, ESP gets mounted at /efi by default.

Oh …wasn’t thinking systemd-boot. I’m just not used to that. I’m more of a grub user.

I’m really not sure what caused all this mess. I think when I had to reinstall windows, it sabotaged EOS like those dimwits probably programmed it to do. I have no idea where to find this shared package library or install it in the correct directory. If you can direct me on the steps I’ll give it a shot, otherwise I’ll resort to reinstalling it. Thanks!

Thank you so much for helping out last night. I learned a lot in the process on how to diagnose issues better. We’ll see if the guys here have a path to installing this package, either way reinstalling EOS won’t be too much of a big deal.

I just had a look at this. is a link to
We could try a similar thing like what you posted from AskUbuntu.
We might get lucky if that is the only broken link/thing.

In the live session:

sudo mount /dev/nvme0n1p10 /mnt
sudo ln -s /mnt/usr/lib/ /mnt/usr/lib/
sudo mount /dev/nvme0n1p9 /mnt/efi
sudo arch-chroot /mnt

IF (read BIG IF) this succeeds and nothing else is broken then

Crossing fingers!

This is crazy but the file exists!?

[admin@A515-54 ~]$ sudo mount /dev/nvme0n1p10 /mnt
[sudo] password for admin: 
[admin@A515-54 ~]$ sudo ln -s /mnt/usr/lib/ /mnt/usr/lib/
ln: failed to create symbolic link '/mnt/usr/lib/': File exists

I’m speechless :no_mouth:

I have other EOS DE’s, maybe it’s overlapping with working DE’s? I’m compiling something right now but can unmount everything afterwards, then try again. Unless there’s a way to mod the command to mount the libread specifically to partition 10’s directory?
