Undefined symbol: _ZN11LanguageTagC1ERKS_

I try to open LibreOffice and I get:

/usr/lib/libreoffice/program/soffice.bin: symbol lookup error: /usr/lib/libreoffice/program/libmergedlo.so: undefined symbol: ZN11LanguageTagC1ERKS

This was after I added the LO PPA and try to install the latest version. Same error happened then, so I removed all the LO packages and went back to the Ubuntu version.

Please report that to the PPA; and don’t forget (as you did here) to include the Ubuntu version you are using, and the PPA version.

You can fix it this way: sudo apt install --reinstall libreoffice

I am using Debian testing version and I faced with this problem. This solution worked for me.

Same here, but new to the platform, so I can not upvote it.

Also worked for me…

After a couple of hours, this is the only way I could fix the problem:

I purged LibreOffice:
sudo apt-get purge libreoffice*

And then I deleted the /usr/lib libreoffice directory:
/usr/lib/libreoffice/program

Did an autoremove:
sudo apt-get autoremove

Then reinstalled:
sudo apt-get install libreoffice

Now LibreOffice appears to be working properly.

worked for me, and clean and well executed on debian…

I did this but I also had to install the package ‘uno-libs3’ afterwards due to the file libuno_sal.so.3 missing.
