Hello there! I have A xiaomi Red Note 7 phone with Sailfish: 3.3.0.16 (Rokua) I'm trying to launch currently supported distributions but the error "The container failed to start."falls out. Tested on different architectures:
debian sid amd64 default 200914_06:02
debian sid amd64 default 200914_05:24
debian sid ramel default 200914_05:24
debian sid armhf default 200914_05:24
debian sid i386 default 200914_05:24
debian sid ppc64el default 200914_05:24
debian sid s390x default 200914_05:24
immediately the question is what architecture is supported by my phone?
I did everything according to the instructions:

lxc-create -t sfos-download -n sid

lxc-start -n sid
The container failed to start.
To get more details, run the container in foreground mode.
Additional information can be obtained by setting the --logfile and --logpriority options.

I will be glad of any help!
