Hi Diego, I've tried reproducing this error in a test environment, but upgrades and fresh installs seem to work without error.
Can you check to see if there actually is a clamav directory in /var/log? I wonder if there might be a permissions or ownership issue... /var/log should look like this: drwxrwxr-x 9 root syslog 4096 Jan 23 12:13 log ** Changed in: clamav (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1812383 Title: package clamav-daemon 0.100.2+dfsg-1ubuntu0.18.04.1 failed to install/upgrade: instalado clamav-daemon paquete post-installation guión el subproceso devolvió un error con estado de salida 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/clamav/+bug/1812383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
