Okay, still a short answer, before I go to bed. That is really strange. Are you sure the file is intact? Did you compare it with a known good backup? You have been able to use it before on Ubuntu 14.04, haven´t you? So in this case I would dig out an older version of the file that works. The one directly before the first attempt to migrate anything. This one should really still work with an KDE SC 4 based distro, cause you used it before like that. Heck, if nothing else works, why not restore your Ubuntu 14.04 completely (system + userdata, at least what is needed for KWallet) in order to access your passwords. > I also did not find a good descriptions of the format kwallet stores its > data ,so I'd be able to write the decrypt program myself.

I´d ask this in IRC, in kde-devel / frameworks-devel mailinglists. I do not have the impression that many KDE developers read this mailinglist regularily. Good luck. -- Martin

Re: Migration of kwallet failed
Hi,
So you still have a working Ubuntu 14.04 install? I missed that in your
original post. In that case I have some PPAs that may be useful for you, on
launchpad, in particular ppa:rjvbertin/qt4 and ppa:rjvbertin/kde-git which
contains newer versions of Qt (4.8.7) and a number of KDE packages (you may
also need rjvbertin/misc). The KDE-Runtime stuff in there is from June 2016 so
must already be aware of its KF5 counterparts.
But as Martin said, make backups first. Or clone that 14.04 install to a VM and
work in there. Apply any Ubuntu updates before cloning, but if you decide to
use my PPAs, add them in the VM first, in case something goes wrong with those.
I'd also suggest to copy the old kdewallet.{kwl,salt} files from a virtual
console or something like that, i.e. without any KDE or other GUI stuff
running. I just hope for you that those files are unaltered.
If kwallet-manager4 continues to fail to start, check with a regular client
application if your passwords are there. If they are, the failure is in
kwallet-manager and there's a bit more hope.
The kwallet protocol isn't super well documented but not rocket science either
- in particular the synchronous API. I rewrote the Mac Keychain backend as one
of my very first KDE contributions, mostly thanks to the self-explanatory code.
It should be possible to write a non-gui utility that opens a given wallet
without going through the kwalletd and which dumps the whole thing. It'll be
tedious, but you should be able to take inspiration from
kdeui/tests/kwallettest.cpp in the kdelibs sources.
FWIW, I ran kwalletd4 + kwallet-manager4 on my Plasma4 desktop, with self-built
KF5 stuff in a separate prefix. Kwallet-manager5 either connected just fine to
kwalletd4 or the 2 daemons didn't bite each other. I noticed at some point that
in practice I was using only the KF5 kwallet so I'm now only running kwalletd5.
I recall that I did a manual migration via an XML dump, but it's possible that
was on my Mac where the KDE4 kwallet uses the host's Keychain backend (a
synchronous mechanism without kwalletd). Probably TMI...
R.

Maybe you need to go back another Ubuntu release for so, to have both old kwalletd and kwalletmanager from KDE SC 4. As the kwalletmanager5 will only access kwalletd5. And you need to make sure that you use the KDE SC 4 wallets in ~/.kde/share/apps/kwallet, not the new ones in ~/.config/kwallet. Another crazy idea of mine: I remember loosely that I may have done something unconventional back then in order to migrate the wallets. I am still not sure whether there is any significant difference between old and new files. So maybe if you just move
fine vertical scrolling with keyboard
[kwin 5.8.7, up-to-date openSuSE Leap 42.3] Folks, within an HTML browser I can easily scroll up and down with the arrow keys which use, say, 100 pixels per keyboard press. Is there a way to have, say, 'Alt + Arrow Key' to move 10 pixels instead? Ditto for one-pixel moves? Werner
