Processing triggers for dbus (1.14.0-2ubuntu3) ...
N: Download is performed unsandboxed as root as file 'full_path_of_deb_file_name' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)Usually apt tries to run the process that fetches packages as a different user called _apt to increase security. That's no problem if it has to download packages from the internet. But if you tell it to install a .deb file that's already on your system, it needs to have permission to access that file by _apt user. Otherwise, above error will be shown.
bash with timestampbashIn order to discard standard output and only log the standard error, following command can be used. The second part of command is to prefix the current timestamp in the output
sh monitor 2>&1>/dev/null | ts '[%Y-%m-%d %H:%M:%S]'dashIf need to run in dash, such as running in crontab, above syntax is wrong, use following command instead
sh monitor 3>&1 1>/dev/null 2>&3 3>&- | ts '[%Y-%m-%d %H:%M:%S]'Note: This command can be run in bash too
