Error starting nextcloud
Getting the following error trying to start the Nextcloud client:
nextcloud: symbol lookup error: nextcloud: undefined symbol: _ZN3OCC18AbstractNetworkJob10davRequestERK10QByteArrayRK4QUrl15QNetworkRequestP9QIODevice
On Ubuntu Zesty. Client installed using the Launchpad PPA. I was previously using the OwnCloud client, so not sure if that's caused a package mismatch somewhere.
Any ideas?
Which version of the ownCloud client were you using previously?
Could you execute the following commands and provide their output:
which nextcloud
ldd `which nextcloud`
I've got a similar error.
nextcloud: symbol lookup error: nextcloud: undefined symbol: _ZN3OCC6Logger21setLogWindowActivatedEb

The problem is most likely this:
libnextcloudsync.so.0 => /usr/local/lib/x86_64-linux-gnu/libnextcloudsync.so.0
This library should be /usr/lib/x86_64-linux-gnu/libnextcloudsync.so.0.
The /usr/local/lib/x86_64-linux-gnu directory is before /usr/lib/x86_64-linux-gnu in the shared library search path on Ubuntu, so probably the best solution is to remove the wrong library file or the package containing it, if any.
@ivaradi Thanks, deleting /usr/local/lib/x86_64-linux-gnu/libnextcloudsync.so.0 worked and now the Nextcloud client is working.
