Clamtk isn't analysing files anylonger

What is the full output of:

sudo freshclam

Thanks

I was a bit surprised : for several days these information ended at line "Don't panic..."

Then I just tried to analyse the "home" files... without any success and no report appears in the "History".

Thank you !

Is the issue now resolved? If so please mark it as such or provide further details.

Thanks

IT ISNT ANSWERED !!!
CLAMTK STILL NOT RUNNING ! AND THERE WAS NO SIGNATURE UPDATED LAST NIGHT !!!

If you rerun freshclam does it work OK? If so then cron the command to run as root at a convenient time

problem isn't solved !!!

Does the freshclam pull in the new defs?

No, it didn't.

Because I had big troubles and because I couldn't analyse it with ClamTk, I rebuilt all the PC. New installation of all the system + new installation of ClamTk.
When I opened ClamTk, I noticed it was listed more than a 100 added signatures (now ClamTk advised that there are 24719 antivirus signatures) . I've tried to analyse the new home with my old files... ClamTk didn't manage any report !
Because with my other PC (Ubuntu) I had to install clamtk-gnome and clamtk-nautilus paquet to let run ClamTk, I install them, too.

And this time I get through the Terminal the following error message :

a@Presario-CQ57:~$ clamtk
Gtk-WARNING **: Attempting to read the recently used resources file at `/home/aidordi/.local/share/recently-used.xbel', but the parser failed: L’ouverture du fichier « /home/aidordi/.local/share/recently-used.xbel » a échoué : Permission non accordée. at /usr/share/perl5/ClamTk/GUI.pm line 675.
a@Presario-CQ57:~$

I tried then with sudo clamtk and ClamTk couldn't analyse the home file. But ClamTk had created the following strange report (0 files in Home ???) :

sudo chown aidordi:aidordi /home/aidordi/.local/share/recently-used.xbel

Then retry

You can run a scan with:

sudo clamscan --max-filesize=3999M --max-scansize=3999M --exclude-dir=/sys/* -i -r /

Dead easy

sudo chown aidordi:aidordi /home/aidordi/.local/share/recently-used.xbel

Didn't run but this time without any error message... And the generated report advise :

As far as sudo clamscan --max-filesize=3999M --max-scansize=3999M --exclude-dir=/sys/* -i -r / is concerned, it doesn't seem, that's run... Nothing appear at the screan except for this command line...

This morning I tried to analyse the Home and was advised that I have first to install clamav-daemon (?? I believed it was installed yesterday)...

During the installation this is the "fatal error" message :

a@Presario-CQ57:~$

Error messages like "Erreur d'entrée/sortie" (I/O error) usually indicate a consistency problem on the file system.

I recommend that you boot an Ubuntu installer in the "Try Ubuntu without installing" mode and perform a full file system check on your root file system.

I just did it by using boot-repair but without any success because of that crazy hyphen-en-g :( I'm fed up with that package !

Did someone know who is in charge of that package ?

This is not a problem with the package, but with your hard disk!

Try the command

cat /var/lib/dpkg/info/hyphen-en-gb.list

What output do you receive?

nothing except for that infernal mention :

aidordi@Presario-CQ57:~$ cat /var/lib/dpkg/info/hyphen-en-gb.list
cat: /var/lib/dpkg/info/hyphen-en-gb.list: Erreur d'entrée/sortie
aidordi@Presario-CQ57:~$

This is the proof, that the problem is not related to the mdadm package.

Error messages like that usually indicate an inconsistency in the file system on your hard disk.

You have to perform a full file system check.

done...
but I can't see anything else that I have to rebuilt the Grub ! and I can't because of that silly "hyphen-en-gb" eventhough you said it isn't the responsable of that situation...

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to enable-raid) and reinstall the grub2 of mapper/xubuntu--vg-root into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s

=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sda (ATA SAMSUNG HN-M500M) !

=================== User settings
The settings chosen by the user will not act on the boot.

Performing boot-repair is something completely different from performing a file system check.
You do not need a boot-repair disk, but an Ubuntu installer disk (or USB stick) (to be started in the "Try Ubuntu without installing" mode).
Then open a terminal window and execute the command
sudo fsck -f /dev/mapper/xubuntu--vg-root

That didn't run properly...

xubuntu@xubuntu:~$ sudo fsck -f /dev/mapper/xubuntu--vg-root
fsck de util-linux 2.31.1
e2fsck 1.44.1 (24-Mar-2018)
/dev/mapper/xubuntu--vg-root est monté.
e2fsck: Ne peut continuer, arrêt immédiat.
xubuntu@xubuntu:~$

You have to make sure that the device is not in use, and if necessary unmount it

sudo umount /dev/mapper/xubuntu--vg-root

and if that works without error re-try

sudo fsck -f /dev/mapper/xubuntu--vg-root

This time I have the message that it didn't exist...
xubuntu@xubuntu:~$ sudo umount /dev/mapper/xubuntu--vg-root
umount: /dev/mapper/xubuntu--vg-root : Aucun point de montage indiqué.
xubuntu@xubuntu:~$ sudo fsck -f /dev/mapper/xubuntu--vg-root

fsck.ext2: Aucun fichier ou dossier de ce type lors de la tentative d'ouverture de /dev/mapper/xubuntu--vg-root
Périphérique peut-être inexistant ?
xubuntu@xubuntu:~$

Maybe it's because I found how to remove this infernal "hyphen-en-gb" and to update the drivers...

I re-install ClamTk and the message was :

aidordi@Presario-CQ57-Notebook-PC:~$ clamtk
Unable to read preferences! No such file or directory

a@Presario-CQ57-Notebook-PC:~$ sudo clamtk
[sudo] Mot de passe de :
a@Presario-CQ57-Notebook-PC:~$

And it's always the same ref the analyse of Home...

Now I will try again boot-repair...

Further to Boot-repair there is no more error message when Clamtk is issued... but ClamTk goes on not analyse the files !

If there was an I/O error with one file, then there is a very high probability that there are more inconsistencies on the main hard disk's file system (which can cause all kinds of strange errors).
I still see the need for running fsck on your root file system.

Because it didn't recognise the command anymore :

xubuntu@xubuntu:~$ sudo fsck -f /dev/mapper/xubuntu--vg-root
fsck from util-linux 2.31.1
e2fsck 1.44.1 (24-Mar-2018)
fsck.ext2: No such file or directory while trying to open /dev/mapper/xubuntu--vg-root
Possibly non-existent device?
xubuntu@xubuntu:~$

and because there is just on file with "mapper" :

xubuntu@xubuntu:~$ ls /dev/mapper
control
xubuntu@xubuntu:~$

I did a fsck -f of the sda1, which is good :

xubuntu@xubuntu:~$ sudo fsck -f /dev/sda1
fsck from util-linux 2.31.1
