The following plugin is incompatible with the current version of KeePass

[sbrl]

I've just tried to install the latest version of this plugin with KeePass 2.29, but it doesn't work. It tells me that "The following plugin is incompatible with the current version of KeePass: /path/to/keepass/plugins/KeePassHttp.plgx.

Here's my uname -a:

Linux Snowflake 4.2.0-16-generic #19-Ubuntu SMP Thu Oct 8 15:35:06 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

If you need more information to track down this issue, please don't hesitate to ask and I''l try to help in any way I can.

Hi, I have the same issue, but with KeePass 2.28.

uname -a:
Linux SG1551 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u6 (2015-11-09) x86_64 GNU/Linux

I have it work with version 2.29 and 2.30:

I copied KeePassHttp.dll and KeePassHttp.plgx and Newtonsoft.Json.dll to the KeePass install directory.

[kowenzhang]

I'm using 2.30. The plugin works properly.

[rojaro]

I am using Ubuntu 15.10 and KeePass2 v2.30 from ppa:jtaylor/keepass (+ mono-complete) and it just doesnt work anymore. Other plugins such as KeeAgent work just fine.

First i tried the "keepass2-plugin-keepasshttp" package v1.8.4 from ppa:dlech/keepass2-plugins which used to work until in the past, but does not anymore.

Then i removed the "keepass2-plugin-keepasshttp" package, and downloaded the pglx file manually and copied it into the /usr/lib/keepass2/plugins directory. Which also did not work.

I also tried to download the dll's and added them as well, but again no luck...

[synchrone]

The issue is that KeePassHttp itself has more dependencies than KeePass itself.

All of them are satisfied if you're a developer and have everything installed.

For the users, the minimal set of Debian\Ubuntu packages looks like:

sudo apt-get install libmono-system-xml-linq4.0-cil libmono-system-data-datasetextensions4.0-cil libmono-system-runtime-serialization4.0-cil

Throw in ``sudo apt-get install mono-mcs` if you want KeePassHttp.plgx on-the-fly compilation support.

[sbrl]

@synchrone Running that command seems to have fixed it!

Does that help for others too?

[bbuck-psd]

It does not help for me (Debian Sid, Keepass2 2.31)

[synchrone]

@bbuck-psd this is not necesarily the case ALL the time. KeePass reports an "incompatibility" for ANY error whatsoever.

To get a stacktrace of an exception that occured during the plugin initialization, run KeePass.exe with --debug flag. Please post it here.

[bbuck-psd]

@synchrone Thanks for the --debug flag tip. I don't think it's necessary to post the stack trace, as the top line clued me in to the fact that not having read permissions on the pglx file might be the issue. One quick sudo chmod 644 /usr/lib/keepass2/KeePassHttp.pglx later, and it loads fine.

[sbrl]

Perhaps an issue should be filed against KeePass2 then? The error message could
certainly be more helpful.

I've encountered this error before and the cause was that I had another instance of KeePass open that was running wild. After killing the errant process and reopening KeePass, the error went away.

[mirekzapletal-cz]

ISSUE:
Incompatible with the latest version of KeePass2 (v2.31)

Environment:
Ubuntu 14.04 64bit

Actions to reproduce the issue:

1. update KeePass2 from v2.30 to v2.31
2. cleanup of Keepass2 plugin cache done
3. start KeePass2

[1] Trying to fix, no success:

1. closed KeePass2
2. manual cleanup of files in Keepass2 plugin cache
3. updated KeePassHttp.plgx in /usr/lib/....
4. start KeePass2

[2] Trying to fix, no success:

1. closed KeePass2
2. double checked that there are no other instances of KeePass2 running
3. CHOWN myself:myself on KeePassHttp.plgx
4. re-start KeePass2

ISSUE NOT SOLVED

Seems like we have to wait for new release of KeePassHttp.plgx

[quanengineering]

@synchrone , it's work for me, thanks. @mirekzapletal-cz you should try synchrone's method.

[synchrone]

Meanwhile, @dlech was so nice as to publish a fixed package together with dependencies to his PPA.

The easiest way would be:

sudo apt-add-repository ppa:dlech/keepass2-plugins
sudo apt-get update
sudo apt-get install keepasshttp

[quanengineering]

thanks @synchrone

[camilleperin]

Wow ! Stuck for 3 days with this one but thanks @synchrone !!

"sudo apt-get install mono-mcs" saved me!

I have installed mono-complete.

@alexpopa Try chmodding that folder with something like chmod -R +r .

@sbrl In the instalation guide it says that I should chmod it to 644. I chaged it 777 and it works. I don't know how safe is this. I'm still a newbie and I have been taught not to mess with chmod.
Thank you! 👍

[sbrl]

@alexgrpopa Oh yeah~! You've just reminded me of something. I think the issue is because the directories are not marked as executable. Strangely enough you can't list a directories contents if it isn't marked executable. So you want to something like this:

find test -type d -print0 | xargs -0 chmod -c 755

The find finds all the directories, and passes them into xargs, which chmods them. The -c parameter just makes chmod tell you if it does anything.

I would recommend messing around with chmod in a safe testing environment where you aren't at risk of breaking anything, like a virtual machine. Understanding how linux permissions work with chmod and chown (and by extension chgrp can be invaluable in keeping your system(s) safe.

Same issue after upgrade ubuntu from 15.10 to 16.04
Plugin incompatible

Description: Ubuntu 16.04 LTS
Release: 16.04
Codename: xenial

KeePass 2.32
KeePassHttp 1.8.4.1

[PPRiphagen]

I also had the problem after upgrading from 15.10 to 16.04
For me the sudo apt-get install mono-mcs did the trick

KeePass 2.32
KeePassHttp: 1.8.4.1

[jgbreezer]

I also found (if I'm not mistaken) that if I had both the .dll and the .plgx files in there, it wouldn't work. The latest .plgx (as I write, Oct 2016) on Keepass2 v2.32 and Ubuntu 16.04 with correct permissions (as per earlier posts) works fine for me once I have enough mono installed (sudo apt install mono-complete was more than enough, I manually installed some other libs mentioned too beforehand). Some other plgx file plugins I downloaded don't work as they need a newer mono and I didn't want to hack with my apt-installed version (or run older plgx's I think) so I went without/used triggers to do the job

[epicstar]

I had this problem, too, on Ubuntu 16.10. I originally thought that chmod 644 KeePassHttp.plgx was enough but it wasn't. It says in the instructions to install mono-complete so I tried that:

sudo apt-get install mono-complete

After I did this, the plugin now works as expected. This ticket should be closed because they already address the issue in the instructions.

[pihentagy]

apt-get install mono-devel was enough for me. But really worth mentioning somewhere!

On my Windows 10 installation, resetting winsock and deleting old lavasoft files as per this thread helped me (scroll down to the last few posts): #275
