Duplicated database entry

Hi everybody,
few days ago I moved /var to a separate partition since there was no space left in root partition. I made some mistakes and now pacman behaves like this:

Apart from the problem with the duplicated packages I do not understand why, for example, nano is for i686 architecture while I'm running a x86_64 system! Is it correct? Does anyone know how can I solve this issue? Which one of the pair of packets should I delete?

thanks

Re: Duplicated database entry

You have restored old /var/lib/pacman/local entries as well as new ones.  I guess the old nano was for i686...

Anyway, go through the list of duplicate entries and fix your pacman database by removing the old one.

Re: Duplicated database entry

Should I always remove the old one?
For example in the case of nano:

pacman -Qi nano
Nome           : nano
Versione       : 2.2.4-1

ls /var/lib/pacman/local/ | grep nano
nano-2.2.4-1
nano-2.2.5-1

Should I remove the old one also in this case?

Re: Duplicated database entry

The old one is probably wrong...

Re: Duplicated database entry

Here's a little python script to remove old duplicates from /var/lib/pacman/local:

#!/usr/bin/env python

import os,re, datetime
d = '/var/lib/pacman/local'

packages = os.listdir(d)
packages.sort()

pkgname_search = re.compile('^(.*?)-[0-9]')

old_packages = []

for pkg1 in packages:
	if pkg1 in old_packages:
		continue
		
	#get package name
	pkgname = pkgname_search.findall(pkg1)[0]
	
	#look for other items with the same package name
	for pkg2 in packages:
		if pkg2 == pkg1:
			continue
		if pkg2 in old_packages:
			continue
		if pkgname == pkgname_search.findall(pkg2)[0]:
			# We now have two duplicate packages, we want to delete the old one
			
			old_package = pkg1
			path1 = os.path.join(d,pkg1)
			path2 = os.path.join(d,pkg2)
			if os.stat(path1).st_mtime > os.stat(path2).st_mtime:
				old_package = pkg2
			
			old_packages.append(old_package)
			#print ('duplicate found:\t')
			#print (pkg1)
			#print (pkg2)
			#print ('old:', old_package)
			
			oldpath = os.path.join(d,old_package)
			target = os.path.join('/var/lib/pacman/OLD',old_package)
			cmd = 'mv "%s" "%s"' % (oldpath, target)
			
			#double-check that the oldpath still exists (it may have been removed in a previous pass)
			if os.path.exists(oldpath):
				print(cmd)
				os.system(cmd)

Run with sudo at your own risk.

Re: Duplicated database entry

Thank you jeffmikels!  I took the "risk" and it worked great, saved a bunch of hassle.
Some might complain about the revived thread, for me it was quite timely.

Re: Duplicated database entry

The script worked great, had to manually create the OLD directory though with:

sudo mkdir /var/lib/pacman/OLD

Thanks!

Re: Duplicated database entry

thank you @jeffmikels
after a problem in my /var due to reiserfs failure I got some pacman's error
I used your script to solve them
