Cannot Start Developer Studio 5.3.1 after OS upgrade on Ubuntu 18.04LTS. When I run studio I can see small window ( screenshot below ), which disappears after few seconds. Nothing shows after this point. Program crashes silently or just close automatically. Can you help me with this? ![image](https://us1.discourse-cdn.com/flex019/uploads/legato1/original/1X/3b295ee3aa1c8e7efbeccfbb1618e9692e436d61.png) ---

I had a problem with dev studio after my java updated, it behaved same. Try starting it from console and seeing if it will give you any feedback why it closed suddenly. My solution was that some paths related to java changed and devstudio didn’t know how to handle that. ---

hi, can you try the solution indicated in this topic? > [@Trouble with Developer Studio on mangOH Virtual Machine](https://forum.legato.io/t/trouble-with-developer-studio-on-mangoh-virtual-machine/3309/3): > > ok, got it. It looks like all the requirements were not installed in the VM. I got it running good by: doing an sudo apt install openjdk-8-jre libwebkitgtk-1.0-0 build-essential python-jinja2 ninja-build zip autoconf automake (as suggested on [https://source.sierrawireless.com/resources/airprime/software/legato\_application\_development\_kit\_linux/](https://source.sierrawireless.com/resources/airprime/software/legato_application_development_kit_linux/)) delete the workspace folder start DS again It should probably help.

Hi, What I did: 1. uninstalled java completely ```auto dpkg-query -W -f='${binary:Package}\n' | grep -E -e '^(ia32-)?(sun|oracle)-java' -e '^openjdk-' -e '^icedtea' -e '^(default|gcj)-j(re|dk)' -e '^gcj-(.*)-j(re|dk)' -e '^java-common' | xargs sudo apt-get -y remove sudo apt-get -y autoremove dpkg -l | grep ^rc | awk '{print($2)}' | xargs sudo apt-get -y purge sudo bash -c 'ls -d /home/*/.java' | xargs sudo rm -rf ``` 1. removed whole legato folder 2. I ran your sudo ```auto sudo apt install openjdk-8-jre libwebkitgtk-1.0-0 build-essential python-jinja2 ninja-build zip autoconf automake ``` 1. I installed legato Results: 1. Developer Studio started and everything looked fine. 2. When I closed DS and reopened. Top bar and all functionality like Run, Debug, Terminal, Connect etc. disappeared. When I went to Windows-\>Perspective-\>Customise Perspective… to add buttons, error pop up. 3. Functionality and top bar did not come back when I created new workspace. 4. I repeated the whole procedure 3 times with the same results. I use linux ubuntu 18.04LTS. DS was working ok on the machine. Problems started after linux auto update. ---

hi @TheGod, it seems the issue happens after an updgrade of ubuntu, not directly link to devstudio. then Devstudio is now replace by VScode, so no more support is done on devstudio tool. I suggest you move your project on VScode. Best Regards ---

Hi @plu, I know it happens after ubuntu upgrade. I use both VScode and DeVStudio. I think DevStutdio is more user friendly. VSCode is really annoying. Reports problems where are no problems, so you never know if it is real or VScode reports it without reason.
