NEED to BUMP ----Update issue

Sorry to Have to Bump but im no further solving this !!

Hi guys
After months of no issues I have hit a wall with this Update

I have a pretty much original instalation and it usually updates quite quick…today it took a couple of hours to calculate dependancies and then i got this below…first time it highlighted chromium as being masked …which it wasnt, or not by me…anyway i tried uninstalling it

but on cl -update i get the readout below…which i dont understand at all so if someone could be kind enough to direct me to the right way of fixing this i would be very grateful

_******I do have and have had for a while a problem with browsers not working within the sandbox which i run

 qupzilla --no-sandbox

but it has never affected an update before*****

What distro do you use?

well its the latest Calculate Linux 17.12.2 xfce 32bit which ive been updating for 2 yrs approx

everything is working ok apart from this update and browsers running in a sandbox…

Can you attach archive of /var/db/pkg ?

tar cjvf /tmp/vardbpkg.tar.bz2 --exclude=environment.bz2 /var/db/pkg

I Have attached the above needed archive in this Pastebin link i think …i had capatch issues

Thank you for taking the time to look at this for me

I updated about 2 weeks ago with no problems and no problems since with daily useage …My problem with Browsers not running in the sandbox has been around for a while

Unfortunately, pastebin has only kept the list of files, but content of files is important also. Can you send this archive to my email

Have sent to your e-mail from and alternative source…Gmail wouldnt allow it …
