slackpkg interruption


Hi - was maintaining a remote server over vpn and running slackpkg upgrade-all. I walked away for a bit and lost my vpn - this before I was able to chose what I wanted to do with the config files of the upgraded programs. When I log back into machine and run slackpkg it says there is a version running already or I can choose to remove lock file.

1) Does slackpkg automatically chose a default option on config files after a period of time and if so what is its default selection - i.e. (K) keep old and review new later

2) Is it possible to bring up the currently running slackpkg session and if so how - jobs does not show any running process

The message you got come from this code snippet in /usr/libexec/slackpkg-core-functions.h:
Code:
	# Checking if another instance of slackpkg is running
	#
	if [ "$(ls /var/lock/slackpkg.* 2>/dev/null)" ] && \
		[ "$CMD" != "search" ] && \
		[ "$CMD" != "help" ] && \
		[ "$CMD" != "file-search" ]; then
		echo -e "\
\nAnother instance of slackpkg is running. If this is not correct, you can\n\
remove /var/lock/slackpkg.* files and run slackpkg again.\n"
		cleanup
	else        
		ls /var/lock/slackpkg.* &>/dev/null || \
			touch /var/lock/slackpkg.$$
	fi
So it's triggered by the presence of a lock file, not a running process.

1) I don't thinks so.
2) I don't think so. However maybe not a "clean" way, I'd just remove the lock file (see above) and restart slackpkg, if the cleanup function in aforementioned script don't do that itself.

The (K) option really describes what has *already* happened, so yes, in that sense it is the default. The other options do more stuff when you select them, the (K) option really just exits.

If there is no running process then there is no currently running slackpkg session. You just need to remove the lock file that the old process left behind when it died, there is nothing else to worry about.

if you don't want that network problems interrupt anything you do in a terminal on a remote host, launch the processes on the host in a tmux (or screen) session.
