Description diego w 2011-07-03 19:50:56 CEST

Description of problem:
I was stupid enough not to realise somehow mixing in cauldron (mga2) rpms into my mga1 while upgrading from mdv 2010.2

i then tried to find a way to go back to the mga1 rpms but this seems as far as i found out impossible unless smart is available or I do all the rpms by hand with rpm itself...

maybe adding a parameter --oldpackage to urpmi like in RPM might be feasible.

Hi Diego,

sorry for responding so late. We are short on triagers.

I don't think downgrading in this way is a good idea. Newer versions of packages are made to upgrade to, not to downgrade from and aren't usually tested to see how well the downgrade goes. It would take an enormous effort to start supporting downgrading from cauldron to 1

If I were you, I would do a fresh Mageia 1 install and  format / but  not format /home

Status: NEW => RESOLVED

Resolution: (none) => INVALID

Hi Marja,

thanks for your reply.

I understand the impact, and I know you are just a small group. 
I heard smart was able to do it.. is that true? (I never used smart myself)
In my opinion an option to allow force overwriting with a few are you sure what you are doing might help...

the bad thing to me was, that accidentally i switched to cauldron, i still dont understand how it happened.

but in the mean time im sort of happy it happened ;-) and have to give the mageia community a big compliment: cauldron never was unstable over the whole time, never broke to a point where it was not recoverable with graphical tools (my past with SID was definitely different) except for a few glitches with sound i enjoyed cauldron so far and am looking forward to maybe switch to mageia 2 in a few months (or stay with cauldron)

i  wish i could be of more help, than just filing useless bugs and promoting mageia in my personal environment.
