What curl version do you have installed.

Try deleting /var/lib/pacman/sync/core.db.part
Comment by Dharmesh Pandav (mrpandav) - Wednesday, 03 May 2017, 05:45 GMT
same result,
tried commenting out core.db from pacman.conf

next the error was for extra
Comment by Allan McRae (Allan) - Wednesday, 03 May 2017, 06:03 GMT
Do you have gdb installed? Can I get a backtrace?
Comment by Dharmesh Pandav (mrpandav) - Wednesday, 03 May 2017, 06:27 GMT
No I do not have it installed

Can you write to /var/cache/pacman/pkg/? Try uncommenting a XferCommand value in your pacman.conf to see if that helps.
Comment by Dharmesh Pandav (mrpandav) - Wednesday, 03 May 2017, 07:10 GMT
there were two option to Xfer one using curl other with wget
#XferCommand = /usr/bin/curl -C - -f %u > %o
#XferCommand = /usr/bin/wget --passive-ftp -c -O %o %u

I have un-commented one with curl

after that, I tried
sudo pacman -Syu

error:

I have created a file with sudo in /var/cache/pacman/pkg/ dir and was able to save it
Comment by Allan McRae (Allan) - Wednesday, 03 May 2017, 07:17 GMT
can you run "file /var/lib/pacman/sync/extra.db"?
Comment by Dharmesh Pandav (mrpandav) - Wednesday, 03 May 2017, 07:23 GMT
# /var/lib/pacman/sync/extra.db: HTML document, ASCII text, with CRLF line terminators
Comment by Allan McRae (Allan) - Wednesday, 03 May 2017, 07:27 GMT
Can you please attach that file?
Comment by Dharmesh Pandav (mrpandav) - Wednesday, 03 May 2017, 07:39 GMT
please find attached the extra.db file




   extra.db (0.2 KiB)
Comment by Allan McRae (Allan) - Wednesday, 03 May 2017, 07:45 GMT
If you look in the file, it is a 301 page. Not sure why you are getting that - using that mirror here handles the redirect fine. Just change mirror for a workaround.
Comment by Dharmesh Pandav (mrpandav) - Wednesday, 03 May 2017, 08:16 GMT
I have copied mirrolist from my other working ArchLinux system

after that did a pacman -Syu and it seem to be running, will update here
Comment by Dharmesh Pandav (mrpandav) - Wednesday, 03 May 2017, 09:10 GMT
it did work but throws error after downloading all the packaged

File xxx is corrupted ( invalid or corrupted package (checksum)),
Do you want to delete it? [Y/n]
Comment by Allan McRae (Allan) - Wednesday, 03 May 2017, 10:28 GMT
Any packages that were downloaded while you were having an issue with that mirror will need deleted.
Comment by Dharmesh Pandav (mrpandav) - Thursday, 04 May 2017, 08:48 GMT
yes, it did work ( creating a new mirrorlist file)


had to clean package cache -Sc and -SCC

and than pacman -Syu <--- worked !
Comment by Allan McRae (Allan) - Monday, 08 May 2017, 09:01 GMT
I am not closing this because we should not segfault when this happens.
