I upgraded my notebook from Ubuntu 14.04 to 16.04. Since then, Openconnect stopped working and is giving me the following error message when launching:

openconnect: error while loading shared libraries: libgnutls.so.26: cannot open shared object file: No such file or directory

All the other libraries seem to be there:

ldd $(which openconnect)
linux-vdso.so.1 =>  (0x00007fff991ef000)

libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f39c3f5a000)

It seems like the package is not available in the Ubuntu repositories any more. There is an Openconnect package though, but how is that supposed to work then?


I needed to

  1. apt purge openconnect
  2. apt autoremove (to remove libopenconnect)
  3. apt install openconnect

Now openconnect links against the newer (and available) libgnutls30.
