Problem installing teensyduino on Ubuntu 18.04.1 LTS

[Roger Parkinson]

It was running just fine even after the Linux upgrade but I was messing about with my libraries and screwed up something, thought it best to just install the latest Arduino and latest Teensydunino.
Ardunio loaded just fine, so I downloaded the teensy file, unzipped and ran the teensy file that comes with it.
It returns immediately, no errors, nothing. I saw somewhere that 18.04 might not have been tried yet with teensyduino but that was when 18.04 was just out and it isn't so new now.
I checked I downloaded the correct file and I've done this a dozen times in the past so I'm probably not doing it wrong (though that's always possible).
Any ideas?

Probably not relevant but this is Xubuntu rather than Ubuntu, different UI layer, which has always worked just fine in the past.

I'd try running it under strace. Might give a clue about where it's dying.

Unzipped? The Linux Teensyduino installers are executables, not zipped.

I believe

sudo apt install libexpat1 libfontconfig1 libfreetype6 libgcc1 libpng12-0 libstdc++6 libx11-6 libxau6 libxcb1 libxdmcp6 libxft2 libxrender1 zlib1g

will install all necessary packages for Teensyduino 1.44 on Debian, Ubuntu, and Mint. However, I checked the libraries and packages on 16.04.4 LTS, so I am not 100% certain.

I restored some backups and went back to 1.8.3 which is working fine.
But thanks for the responses, guys.

anyone ever figure this out? I'm having issues with 18.04, won't install.

seems like it has no idea what to do with the install download file.

ok, easy fix, permissions. Downloaded file was not set to be executable, problem solved.

can't get Teensy to work since I installed Ubuntu 18.04, some time ago.
Compilation (Blink) works but download fails.
lsusb gives
Bus 001 Device 031: ID 16c0:0478 Van Ooijen Technische Informatica Teensy Halfkay Bootloader
dmesg gives

I have another one where lsusb only gives

and dmesg gives

This one gives

despite a picture of the teensy appearing on the task bar.

teensy udev rules were updated in the last few months, make sure you have installed the latest 49-teensy.rules

[George Shering]

Thanks manitou. That worked. In fact my 49-teensy.rules had got itself renamed to 49-teensy.rules.txt in the changeover from 16.10 to 18.04.
So the rules file effectively did not exist.
