I can't, because it didn't sync till the end ( lack of space ), so I backed up wallet and purged bitcoin core. Can I import that wallet.dat in new Bitcoin core if I install it and sync it, and if I have to, how can I recover wallet ( if it's corrupted ) ?

Pywallet online says 'Dump page error' and while trying to dump it in terminal it says:


 Wallet data not recognized: {'__type__': 'destdata', '__value__': 'O\x01\x00\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00k\x07TX\x01\x00\x00\x00"1CsmG9zjR41aiHCHWKqvgcp54ZEWys8T48\x06Uplate\x00\x8c\xb9\x00\x00\x00\x00\x00\x06Uplata\x00\x00', '__key__': '\x08destdata"1CsmG9zjR41aiHCHWKqvgcp54ZEWys8T48\x03rr1'}

( this is just example, it posted a bunch of similar stuff )

and in the end:
Traceback (most recent call last):
  File "pywallet.py", line 2111, in parse_wallet
    d.update(parse_BlockLocator(vds))
TypeError: 'NoneType' object is not iterable

What should I do ? How can I find private key from wallet.dat ?

I didn't knew what to type for version so I left 0 on web pywallet

Pywallet responds with 'Error with Dump Page'. What should I do ?

I did. It says 'wallet corrupted'

I can not go back to original install. Altough I backed-up everything to the other partition and deleted original /.bitcoin folder, everytime I purge bitcoin-qt and re-install it it starts with already made new /.bitcoin folder.
I cleared some space and it's ok if Bitcoin core uses more of it, but I don't know how to continue with synchronozing and not lose payment I got on previous wallet which is backed-up.

My bitcoin core had around 2 more hours of syncronisation before I ran out of free memory on that partition. I did recieve bitcoins for adress on that wallet and I have complete backup of both wallet and whole /.bitcoin folder on other partition. On partition where was bitcoin core is Xubuntu 16.10 and on the other one where I backed-it up is Debian 8.0. I installed armory on Debian but it could not import wallet while it's synchonizing, and it could not sync because I dind't had bitcoin core installed. Which Bitcoin wallet should ( and which ones I even can ) I install and on which partition ? How can I import backup ?
