Nixnote2 is an app to download Evernote contents. Its easiest to compile the source as there are quite a number of resource to refer. Installing the ready Deb file however, lacked the required steps. For Linux Mint, here are the steps where updates can be found at tboxmy.

Step 1: Download nixnote

Locate the file online from Sourceforge and download. The file I downloaded to my Download folder is

nixnote2-2.0.2_amd64.deb
 

Step 2: Install from command prompt

$ cd ~/Download
$ sudo apt install ./nixnote2-2.0.2_amd64.deb
$ apt install libcurl3 libcurl3-nss

This installed the dependency packages libcurl3, libpoppler-qt5-1 and tidy.
 

Troubleshoot: Error

QSqlDatabase: QSQLITE driver not loaded
QSqlDatabase: available drivers:
ERROR 2018-04-13 00:50:37.788 ( sql/databaseconnection.cpp @ 44 ) Error opening database:  QSqlError(-1, "Driver not loaded", "Driver not loaded")
 

Solution: At CLI type

$ apt install lua5.2-sql-sqlite3
$ apt install libqt4-sql-sqlite
 

Step 3: Run Nixnote

At the Desktop Menu ->Internet ->Nixnote2
 

Troubleshoot: Nothing appears after click Nixnote2.

At CLI the error shows:

nixnote2: error while loading shared libraries: libpoppler-qt4.so.4: cannot open shared object file: No such file or directory
 

Solution: Open CLI and type

$ apt install libpoppler-qt4-4
$ nixnote2
