[SOLVED] updating package.mask

[ceejay82]

Hello folks,
I installed the livedvd 2012 on my notebook this morning and try to update everything.
but when I use emerge -u world I first recieved the usual use flag msg
but after emerge -u world --autounmask-write and etc-update it is still not possible to update
I read the man pages for emerge and mask packages but still don't have a clue what to do.

here is the output I recieve

Ok, when portage does this to me, first I try to get past the blocks without actually masking anything. In your position, here is what I would do:
1) emerge -auvND world
a is for ask v is for verbose output, N is to check for use flag changes and D is for deep. If that does not work, then
2) emerge -auvND --backtrack=30 world
If that does not work you can try increasing your backtrack.
3) start updating several packages at a time. This can take a long time because you need to leave out the packages that are causing you problems. Hopfully if all goes well the will stop complaining after a short time and you can go back to simply using emerge -au world

I don't think you really want to use package.mask to solve your problems here, but if you really need to the file is located at
/etc/portage/package.mask
You will need to create the file. Add packages you do not want installed like this:

It looks like the primary problem is the Qt blockers. The quick approach is to emerge --unmerge all the Qt packages, then emerge the new ones. This will prevent you from starting Qt based programs until you are done with the migration.
