Hi all,

I have mnemosyne synced between my Android phone and my Ubuntu 16.04 LTS machine, and after the Android update (to version 1.1) last night I can't sync due to mismatched versions. I downloaded the Mnemosyne 2.4 tarball, and made sure I had all the dependencies installed, and everything seemed to go okay. But when I tested the installation, I got the following errors:

An unexpected error has occurred.
Please forward the following info to the developers:

Traceback (innermost last):
File "/usr/local/bin/mnemosyne", line 4, in <module>
    __import__('pkg_resources').run_script('Mnemosyne==2.4', 'mnemosyne')

Any idea what the problem could be?

Thanks much,

Hi,

Ubuntu doesn’t seem to package webenginewidgets yet, but as far as I know you can install them through ‘sudo pip3 install PyQt5’.

Cheers,

Peter

I ran 'sudo pip3 install PyQt5' and got the following message:

I reran the mnemosyne setup script, and started it from the command line. I got these errors:

It seemed to start fine, though, and my active database comes up. When I try to start the sync server, though, I get a an error 'Unable to start sync server'. (The 'QIODevice::write (QProcess): device not open' errors seem to pop up when I try to start the sync server)

I'd much appreciate any ideas on how to fix this.

Thanks!

John

Hi,

Probably you still have zombie sync servers running from you previous attempts to run the software. Can you try a reboot?

Cheers,

Peter

It worked!

I still got some of those messages about the QIO Device and sRGB profile, if that helps with anything, but everything works perfectly now.

Thank you!

John
