[SOLVED] slackpkg, download upgradeable packages without installing?

coralfang · 03-17-2021, 05:18 PM

Hi. Is there a simple way to download any upgradable packages without installing them? (for example, when the system is in use, so that it can all be upgraded later offline).

There is this for downloading a package (or list of them)

Code:

slackpkg download <package name>

But ideally i would like to do it for the list of packages that pop up in the menu for:

Code:

slackpkg upgrade-all

My first thought was whether you could combine the two commands, but doesn't seem capable of doing that:

Code:

slackpkg upgrade-all download 

upgrade-all: Ignoring extra arguments: download

Yes. You can download the Slackware Tree you need (download the packages) and then make slackpkg point to that local tree and apply upgrades or make custom ISO however you want to.

Just use rsync, ie:

rsync -aHhv --progress --stats --delete rsync://slackware.uk/slackware/slackware64-current/ /path-to-wherever-you-want-to-save-the-tree

... And execute that command every time you want to download new packages if there is any (check ChangeLog.txt). The --delete flag will delete previous versions of the packages so you only will have the newest packages but if you need to save the previous packages just remove that flag when executing the command.

After downloading the Slackware Tree, just tell slackpkg to apply upgrades from that local tree by modifying /etc/slackpkg/mirrors to point to the folder where you saved the tree to. Then normally do the routine whenever you want to: slackpkg upgrade gpg; update; install-new; upgrade-all; clean-system.

An alternative solution is to create a custom 'cleanup' function for slackpkg to capture the contents of the $LIST variable created when 'slackpkg install-new' or 'slackpkg upgrade-all' are run.
So, in /usr/libexec/slackpkg/functions.d create a file xx_cleanup.sh containing:

Code:

No packages selected for download, exiting.

root@Eagle:~# cat /usr/libexec/slackpkg/functions.d/xx_cleanup.sh

#========================================================================
#
# PROGRAM FUNCTIONS
#

# Clean-up tmp and lock files
#
function cleanup() {
	local retval=0
	[ "$SPINNING" = "off" ] || tput cnorm
	if [ -e $TMPDIR/error.log ]; then
		retval=1
	        echo -e "         
\n==============================================================================
WARNING!        WARNING!        WARNING!        WARNING!        WARNING!
==============================================================================
One or more errors occurred while slackpkg was running:                       
"
		cat $TMPDIR/error.log
		echo -e "
=============================================================================="
	fi    
	echo
	if [ "$DELALL" = "on" ] && [ "$NAMEPKG" != "" ]; then
		rm $CACHEPATH/$NAMEPKG &>/dev/null
	fi		
	rm -f /var/lock/slackpkg.$$
# The next line captures the list from install-new or upgrade-all suitable for use by download
	echo "${LIST//.t[blxg]z}" > /tmp/mylist
	rm -rf $TMPDIR
	exit ${retval}
}

This file needs to be set executable with 'chmod +x /usr/libexec/slackpkg/functions.d/xx_cleanup.sh'.

With this in place you can run 'slackpkg upgrade-all' to see the list, then hit Cancel, so that slackpkg exits dropping the /tmp/mylist file.
To download the files,

Code:

slackpkg download $(tr '\n' ' ' < /tmp/mylist)
