Comment 4 for bug 1746955

Hittin the same problem in the middle of time-critical task. I am working with Arduino based board and an arm based board. Can't even uninstall gcc-arm-embedded. I am using Ubuntu 18.04

’’’
sudo apt-get purge gcc-arm-embedded
[sudo] password for user:

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 arduino-core : Depends: gcc-avr (>= 4.7.0) but it is not going to be installed
 avr-libc : Depends: gcc-avr (>= 5.4.0+Atmel3.6.0-1) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I am not very good in managing packages so this might not be related but I thought I would post it here in case it is related.
