I'm creating a new bitcoin-qt installation on a Linux Mint/ubuntu virtual machine.

I've tried moving the blocks folder over without success

Code:
bitcoin-qt -reindex

will begin reindexing on the disk and then it fails around week 40

What am I doing wrong?

This is the failure:

Code:
bitcoin-qt -reindex
bitcoin-qt: main.cpp:1761: bool ConnectBlock(CBlock&, CValidationState&, CBlockIndex*, CCoinsViewCache&, bool): Assertion `hashPrevBlock == view.GetBestBlock()' failed.
Aborted

core version 9.3.0

I've tried re-indexing with and without a network connection.

I've tried moving over the chainstate folder

I've tried moving every file/folder over except wallet.dat

Reindexing still fails -  Huh

I've tried it now on 9.4.0 too.

Why am I having such difficulty moving the blockchain?

It seems like I did this a few months ago without an issue.

It does seem odd you are having the problem because (as you noted) it is possible.

You might just trying running 0.10.0rc3 and re-download the blockchain.  It will in all likelihood be much faster than banging your head against the wall on this more.  ;-)

He said he tried 0.9.4 (this version came out for Ubuntu only at the moment and coming soon for Windows) , Basically 0.10.0rc3 = 0.9.4 the Final release . so I don't think it will change anything .
Delete all the downloaded blocks & Try downloading the torrent Bootstrap file and place it on the Bitcoin Data Directory and run your wallet again . It should Import from the disk just fine and probably start synchrozning with the network if some blocks missing .

[...]Basically 0.10.0rc3 = 0.9.4 the Final release[...]

This is not correct. 0.9.4 fixed an issue with OpenSSL which affected mainly the Ubuntu PPA. https://github.com/bitcoin/bitcoin/blob/41f94edf221019a6c4b8f78c2b17c389442f546e/doc/release-notes.md

0.10.0RC3 introduces more features i.e. "headers first". Preliminary release notes: https://github.com/bitcoin/bitcoin/blob/0.10/doc/release-notes.md

Additionally RC stands for Release candidate, so it's not a final release.

I'm beginning to think I've encountered a bug in XFCE or core version 9.4.0 and 9.3.0

I've tried moving the blocks [blocks folder] - returns:

Code:
bitcoin-qt -reindex
bitcoin-qt: main.cpp:1761: bool ConnectBlock(CBlock&, CValidationState&, CBlockIndex*, CCoinsViewCache&, bool): Assertion `hashPrevBlock == view.GetBestBlock()' failed.
Aborted

I've tried initializing with bootstrap.dat

This imports blocks from disk- then after a rescan the core fails with no error message.

Any ideas?

I was successfully able to move the blocks to a Windows 10 Tech Preview virtual machine.

I tried on several different Debian and Ubuntu distros and all my attempts failed.
