Fixing "DerInputStream.getLength(): lengthTag=109, too big" in Android Studio

This happened to me in Android Studio after AndroidX migration and using the new testing framework. Even deleting the existing ~/.android/debug.keystore was failing for me

The solution was regenerate it manually (accept all questions as empty and say yes at the last one)

$ keytool -genkey -v -keystore debug.keystore -storepass android -alias androiddebugkey -keypass android -keyalg RSA -keysize 2048 -validity 10000

And copy it

$ rm ~/.android/debug.keystore
$ cp debug.keystore ~/.android/debug.keystore

Simple Samba setup on Lubuntu

I have a simple lubuntu server where I setup a ssh server. While it is sufficient to access a driver/folder from another linux machine using sftp, it is a pain from Windows & Mac, so unfortunately, samba is still needed here. For simplicity I needed only one samba user that I could map to a single user on my lubuntu machine Following the various tutorial I ended up doing this with simple commands Install samba $ sudo apt-get install samba Add myuser to the samba $ sudo smbpasswd -a myuser Export the drive I needed (no guest user) $ sudo vi /etc/samba/smb.conf to add the following export (no real option needed here) [files] path = /media/music/files writeable = yes save and Restart samba $ sudo service smbd restart

Solving: insufficient permissions for device: user in plugdev group; are your udev rules wrong

This happens on Ubuntu almost each time I add a new device: Check that your are in plugdev group $ id uid=1000(alex) gid=1000(alex) groups=1000(alex),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),116(lpadmin),126(sambashare),127(kvm),129(libvirt),134(chrome-remote-desktop) If not (i.e. plugdev not displayed), add it: $ sudo usermod -aG plugdev alex If you get 'insufficient permissions for device: user in plugdev group; are your udev rules wrong' when trying to debug, you'll need to add your device: First i used lsusb to find my vendor id (here I guess google) $ lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub ...
