I installed clamav and clamtk. clamtk GUI is visible but seems to do nothing. If I do: clamav on the CLI I get clamav: command not found. If you do: sudo clamav clamav-freshclam I also get:clamav: command not found. If I do : freshclam, I get: ERROR: Can't open/parse the config file /usr/local/etc/freshclam.conf Reinstalling clamav and clamtk (sudo apt-get install clamav clamtk) does not help.

Who can help?

clamav is already the newest version (0.105.0-1).
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

I added spaces in the urls because I am not allowed to use much links I use GalliumOS, which is Xubuntu for Chromebooks. Version 3.1

  • what is the output from sudo apt install --reinstall clamav? – Esther Jul 13 '22 at 14:32
  • jan@galliumos:~$ sudo apt install --reinstall clamav [sudo] password for jan: Pakketlijsten worden ingelezen... Klaar Boom van vereisten wordt opgebouwd
    De statusinformatie wordt gelezen... Klaar Herinstalleren van clamav is niet mogelijk omdat het niet opgehaald kan worden. 0 opgewaardeerd, 0 nieuw geïnstalleerd, 0 te verwijderen en 3 niet opgewaardeerd. This output is in Dutch; the last part translates as: reinstall of clamav is not possible because it cannot be picked up.     – Johan Staal Jul 13 '22 at 16:05

    so you don't have clamav installed. of course it won't work. You have to figure out why "it cannot be fetched". It would be very helpful to post output from sudo apt update and sudo apt install clamav in English. You can run export LANGUAGE=en_US before running apt commands to temporarily (until you close and re-open terminal) switch language to English. – Esther Jul 13 '22 at 16:15

  • Gallium OS is not an official Ubuntu version and it's not supported on Ask Ubuntu. – karel Jul 15 '22 at 05:35

The name of a package is not always the name of the executable. To see the list of files installed by a package, run dpkg -L package-name. In this case, the executables are:

$ dpkg -L clamav | grep /bin/    
/usr/bin/clambc
/usr/bin/clamscan
/usr/bin/clamsubmit
/usr/bin/sigtool

The one you're looking for is most likely clamscan, to scan a file or directory for virus. For example:

$ clamscan /tmp/clam/     
/tmp/clam/foo: OK
/tmp/clam/bar: OK

  • Have solved it by using App-grid package manager. But not satisfied because it is not clear to me why it did not work with apt-get install... – Johan Staal Jul 13 '22 at 19:33
  • In a suggested edit, you show that you have a file /usr/local/bin/clamscan instead of the normal /usr/bin/ one. Please post the output of apt policy clamav in your question, you apparently installed a non-standard version of the package. – Matthieu Moy Jul 13 '22 at 20:23
  • Thanks, I just used the "normal" clamav installation commands. I cannot do the suggested check because in the meantime I used package manager Appgrid to install the package. And now it works fine. – Johan Staal Jul 14 '22 at 09:07
