@user_profile555 I might not be understanding you correctly: Are you trying to install a .jar file with the libertine-container-manager command line tool? That is not going to work, the install-package subcommand only understands how to deal with .deb packages. This .jar file, how would you go about running it on Ubuntu Desktop? That might give us an idea as to how you should go about this, if it is possible at all.

@MrT10001 I made progress. Now it's stuck on "deleting logical partition" for an hour : [image: 1692029706215-9a0936d1-60dd-43c9-b6ad-258d732edab4-image.png] The phone display the fastbootd screen : [image: 1692029997586-344929b3-9717-48b0-877f-41c09aa21c7c-image.png]

@ygrex I suggest you look at https://forums.ubports.com/topic/7283/anbox-support-for-the-fairphone-3-3/2?_=1673700715553 Use Waydroid in preference to Anbox. Having said that I haven't installed either. I tried Waydroid using Waydroid Helper from OpenStore but I somehow managed to almost brick my Volla Phone X and lost all my data getting it working again. I'm sure it was just me doing something stupid, but be careful.

@stanwood - Thank you for the heads-up!
