  Cheers to all.

  I just installed libssl-dev on ubuntu 11.10. Now my Mendeley works fine.ç

  In Ubuntu 11.10, freshly installed today 3/1/2012, installing the package libqt4-webkit solves the problem.

  Following your suggestion, I downloaded again the package and now the installation works fine! Thank you very much for your help!

  @Francesco Cambuli: this is probably a not-fully-downloaded package -- the error you get is commonly seen when the package is being decompressed, and part of the archive is missing. Please try to download it again, and then try to reinstall with 'dpkg -i'.

  I recently started to use Ubuntu 11.10(64 bit) and I was unable to install Mendeley. I tried to use two different commands (dpkn or apt-get) and I also installed several packages via the Installation Center (libssl0.9.8, libssl-dev, libqtwebkit4) but I got the following error messages:

  -----

  I had the same issue. What solved it for me was just installing libssl-dev.

• Randy Ballesteros commented  ·  December 13, 2011 17:04  ·  Flag as inappropriate  ·  Delete

  how did you do that?

• martin commented  ·  November 28, 2011 14:49  ·  Flag as inappropriate  ·  Delete

  installing libssl0.9.8 from the software centre worked fine for me also. thanks for tip.

  Thank you. One additional item -- we use 'dpkg -i' to install the package. 'dpkg' does not resolve dependencies, so we still risk a failed install because the QT libraries were not installed. A way out of this is to instruct the users, if installation fails because of missing libraries, to run 'sudo apt-get -f install'. This will install the missing dependencies.

  Hello C de-Avillez

  Mendeley is bundled with its own version of Qt which can be used on systems that do not have a new-enough version installed system-wide - hence Qt is recommended rather than a dependency (aside from the recent issue with Ubuntu 11.10). What I will likely do is change 'Recommends' to 'Depends' but not specify the minimum version so that Mendeley can continue to function on older systems.

• C de-Avillez commented  ·  October 30, 2011 08:42  ·  Flag as inappropriate  ·  Delete

  This is actually a packaging issue -- if mendeleydesktop depends on some of the libqt*, they should be set as 'depends' on ./debian/control; instead, all I can see is 'recommends'. So... an install of mendeleydestop will only work if (1) the system is set to automatically install 'recommends', or (2) you are running KDE (which will bring in the required QT libraries).

  There are some other issues in the packaging as well.

  How to install "libssIO.9.8" from the software center? The center returns that no package is found...

  I have the same problem. Mendeley is using bundled qt, although I think that I have qt installed. Maybe because mendeley looks for a specific version and the version of Ubuntu 11.10 is newer? Starting with --force-system-qt solves the problem

• Davide Aversa commented  ·  September 25, 2011 01:30  ·  Flag as inappropriate  ·  Delete

  Try with "--force-system-qt"

  Hello - Can you run Mendeley Desktop from a terminal and see whether it is using system Qt or bundled Qt. If it is using bundled Qt, try installing Qt from the Ubuntu repositories and see whether that resolves the problem.
