Ubuntu 16.04: utf8 missing?

[daniela-waranie]

I run this box: bento/ubuntu-16.04

And tried to use autofs to mount some samba shares and noticed that i can mount it when i ommit the "iocharset=utf8" parameter. But when i use the iocharset paramter i get this error:

attempting to mount entry /var/ncdatadir/qnap
>> mount error(79): Can not access a needed shared library
>> Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

What i did before:

sudo apt-get update
sudo apt-get install -y autofs cifs-utils linux-image-extra-virtual
reboot
sudo mkdir -p /var/ncdatadir
sudo nano /etc/auto.master
#add: /var/ncdatadir   /etc/auto.mountqnap
sudo nano /etc/auto.mountqnap
#add: qnap -fstype=cifs,rw,user=myusername,password=mypassword,file_mode=0770,dir_mode=0770,nounix,uid=33,gid=33,iocharset=utf8 ://192.168.8.4/myshare
service autofs stop
#ensure via ps aux if there is another automount process, kill it 
#to bring debugging info to the foreground:
sudo automount -v -f
#launch a 2nd terminal.
cd /var/ncdatadir/qnap

First issue at a vanilla box was that /sbin/mount.cifs was missing. That is the reason why i installed cifs-utils. Then the above error appeared. Then followed these tips here:
https://askubuntu.com/questions/519796/unable-to-mount-cifs-with-iocharset-utf8-in-trusty

uname -r
4.8.0-51-generic

I can confirm that ls /lib/modules/$(uname -r)/kernel/fs/nls/nls_utf8.ko is missing:
ls: cannot access '/lib/modules/4.8.0-51-generic/kernel/fs/nls/nls_utf8.ko': No such file or directoryMeans the complete directory "nls" (natual language support) is missing.

dmesg shows this error:
[ 12.549080] random: crng init done
[ 247.824290] FS-Cache: Loaded
[ 247.838457] FS-Cache: Netfs 'cifs' registered for caching

[ 247.840226] CIFS VFS: CIFS mount error: iocharset utf8 not found

apt-get install -y linux-image-extra-virtual (version 4.4.0.77.83) should install that, but it seams to be still missing.

I am absolute confused that nower days UTF8 is still not included in a minimal install. Kernel modules, and such stuff is really hard to me...

How to fix that? Or is there an ubuntu 16.04 full install available for download with vagrant?

This is an ubuntu issue as bento just builds a virtual image out of the default minimal installation.

See:

http://packages.ubuntu.com/search?searchon=contents&keywords=nls_utf8.ko&mode=exactfilename&suite=xenial&arch=amd64
http://packages.ubuntu.com/search?searchon=contents&keywords=nls_utf8.ko&mode=exactfilename&suite=xenial-updates&arch=amd64

just install the kernel package you like and reboot the VM.

Thank you very,very much. I did not expect that the latest release is somehow incomplete.

I installed linux-image-extra-4.4.0-21-generic and rebooted. But it seams that the kernel do not pick hat module. Still the same error as above. uname -r says: 4.8.0-51-generic

I'm not sure, but i think i need to boot into linux-image-4.4.0-21-generic - but how to tell grub to load that old kernel at next boot without GUI? (i am using virtualbox in headless mode on a server)

I will ask that question at a ubuntu forum and close this ticket now
