App dos't start - please help!

I’m using Cryptomator for a few years an my Mac. It works fine.
Now I’ve installed it on my Linux-Computer (Archmerge), but it cannot start:

[micha@ArcoLENOVO ~]$ cryptomator

What’s wrong? What can I do to use my Cryptomator?

Download Cryptomator-1.3.3.jar
Put into your home folder
Then in the terminal > java -jar /home/YOUR NAME/Cryptomator-1.3.3.jar <
(sorry don’t know what Linux OS you have)

Sorry, but that does’nt help!
My OS ist ArchmergerD (an Arch Linux) and in past Cryptomator could be installed from AUR (Arch User Repository) an dit worked fine. Now, in my OS it does not start! I tryed your advise, but it’s the same result.
Linux ArchmergeD, XFCE4, Kernel 4.14.28-1-lts
CPU: Intel i5 M 450 (4) @ 2.400GHz
GPU: GPU: NVIDIA GeForce 310M
RAM: 8 GB
Please find and fix the issue and feel free to contact me for further informations!

Hi mirolPirol, I’m using manjaro OS.

To install AUR use > sudo pacman -S yaourt <
then to update the AUR packages > yaourt -Syua <

Cryptomator version 1.3.2.1 is in the AUR
The java version is at: https://github.com/cryptomator/cryptomator/releases
this is the latest version 1.3.3

So you have two options. (both worked fine for me) The AUR one my be the best for you to try first as all the dependencies will be installed.

If I were you, when installed I would test cryptomator is working OK by making a folder in your /home directory, and connect to that before trying to connect to a cloud server.

Have fun Paul
