Iam getting this error when starting wireshark
wireshark: error while loading shared libraries: libgnutls.so.13: cannot open shared object file: No such file or directory
Hdd install
Acer Aspire 5502Z

Wireshark had been working with no problem. Slap-get --update then slap-get --upgrade done last week (forget what all were updated iam a noob ). No new installs of programs since --upgrade

Searched the forums
Searched google found reinstall of gnutls may fix but no joy.
Uninstalled wireshark and reinstalled no joy

All posts welcome even to tell me iam a noob , wipe and start again
