Can someone upload their blk0001.dat and blkindex.dat files?
What version of the client are you running?
Done:
blk0001.dat
blkindex.dat
blkindex.dat is currently being uploaded. This will take some time. I will update this post.

Thanks, im running 2.0.3, this is all sorts of painful. It just changed its total block count to 690618, from 344787, it does this everytime i run the client, so now instead of being 50% there im only 25%.
Downloading your blockfiles now…
Well it downloaded ok, extracted to the data directory, it returns this error:
EXCEPTION: 11DbException
Db::open: Invalid argument
nu in Runaway exception
This is a blockchain, it should be identical for everyone, why would this return an error?
Either the files are corrupted or it’s something different.
The dat files are from my RaspberryPi running Raspbian.
I’ve compiled nud with BerkeleyDB4.8.
Do you use an official wallet software or did you compile it yourself?
I suppose you compiled your own version.
BerkeleyDB4.8 files might not be compatible with your version of the Nu wallet software.
Can you test the files with an official Nu wallet version from the download section on any machine - just to make sure they work?
Yeah once this is done i can jump onto windows and try the windows client. It looks like its going to be at least 7 more days at this point
We can try to help improve the current performance but until 2.1 is released there aren’t many better options.
Doesnt look like 2.1 is going to be released:

sigmike has spent the last month on Nu version 2.1, which is also now code complete and partially tested.
2.1 has been code complete since october and now its janurary, it looks like development is dead.
Here is a list of the changes in 2.1. They are extensive changes. It is not a simple feature update like previous releases. The blocker right now is performance related. Once we identify the source of the performance issues and fix them it should be ready for release.

make sure to delete addr.dat, log/, and has an empty walletS.dat, before starting with downloaded blk.dat
if you still get problems, tell us the last 20 lines in db.log and debug.log
I removed all the old files and brought in the two downloaded database files, db.log says:
file blkindex.dat has LSN 11813/8847726, past end of log at 1/17684
Commonly caused by moving a database from one database environment
to another without clearing the database LSNs, or by removing all of
the log files from a database environment
__db_meta_setup: /home/amnesia/Persistent/nubits/Data/blkindex.dat: unexpected file type or format
Database handles still open at environment close
and debug.log says:

How do i remove all old database .lsn’s?
After leaving the client on all night again it downloaded 120MB, the blockchain files only increased by 40MB, and the status bar only increased by 2%, so it will take at least several weeks of leaving my computer on to finish.
What’s the BerkeleyDB version you compiled the Nu wallet with?
Like I said, the dat files are generated by a Nu wallet compiled with version 4.8 and aren’t compatible with newer versions.
I have no idea, i took the code from this guys thread
Whoops its paraphrasing my post on the thread for some reason, this is the code
sudo apt-get install qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev libssl-dev libdb5.1+±dev build-essential libssl-dev libboost-all-dev libqrencode-dev libminiupnpc-dev qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev libssl-dev
Step 3. Delete datafeeds related code.
In Makefile just search for any dependency or target that has the phrase “datafeed” as part of the name and delete it.
The following files in src and src/qt must be modified:
init.cpp : delete lines with “curl” in them.
main.cpp : delete the four lines starting with "if (strDataFeedError != “”)"
bitcoinrpc.cpp : delete all code related to “setvote” “setdatafeed” and "getdatafeed"
net.cpp : delete the line "StartUpdateFromDataFeed();"
bitcoingui.cpp : delete code related to votePage and gotoVotePage
bitcoingui.h : delete code related to votePage and gotoVotePage
votepage.cpp : delete code mentioning "datafeed"
votepage.h : delete line "void on_dataFeedButton_clicked();"
walletmodel.cpp : delete code mentioning “datafeed”
Step 4. Compile a version that doesn’t need the dependencies.
qmake "RELEASE=1"
make
This should make an executable called “nu” which can be run in the
future with a fresh Tails. You should copy this somewhere, like a flash
drive at /media/nuflash. Later you can start it in a fresh Tails like:
/media/nuflash/nu -datadir=/media/nuflash/.nu -proxy=127.0.0.1:9050
Hope this helps someone. I’m not sure what effect deleting the
datafeed related code has, but it is able to keep up with the block
chain and send transactions. That’s good enough for me.
Someone might advise that there’s an easier way, but until then at least there is some way.
Try
dpkg --get-selections | grep libdb
to determine your version of BerkeleyDB.
I bet it’s 5.1 or newer.
ninjaedit: with your last update to your post I think we’ve found the likely issue - libdb5.1
Have a look at https://docs.nubits.com/nu-raspberry-minting/ which contains a guide how to compile libdb4.8
amnesia@amnesia:~$ dpkg --get-selections | grep libdb
libdb5.1:i386 install
libdb5.1++:i386 install
libdbus-1-3:i386 install
libdbus-glib-1-2:i386 install
So what do i do, will this not work with nu or am i forced to wait on this to download?
Compile a new version of the Nu wallet using libdb4.8.
I’m not 100% sure, but quite confident that this will solve the problem.
Plus it will make the files created by your Nu wallet compatible with official releases (important for walletB.dat and walletS.dat).
Is there anything from that large block of apt-get code i should remove? That nuclient was the first thing ive ever compiled and i dont know what any of that code means
First
sudo apt-get remove libdb5.1++-dev
Or whatever is needed to remove libdb5.1.
Then follow the guide to compile libdb4.8.
Then compile Nu wallet using libdb4.8.
I followed your guide all the way up to
make -f makefile.unix
and it gives me this error:
root@amnesia:/home/amnesia/Persistent/nubits/src# make -f makefile.unix
make: makefile.unix: No such file or directory
make: *** No rule to make target `makefile.unix’. Stop.
But i had to skip the nubits download section because i already downloaded it and did alot of editing to all the files to get it to work in the first place. I did try to make it with the makefile i previously had but it threw an error so i deleted it figuring it was based off the old dependecies. Then i tried using
qmake “RELEASE=1”
but it says command not found.
