It's doesn't work

[dimka11]

I have tried to get it works on two systems (Colab and Ubuntu in WSL2) and get the same error:

dima@DESKTOP-5SK57UV:~$ lzy-terminal -u dimka11 -k ~/.ssh/private.pem
/home/dima/.local/lib/python3.9/site-packages/lzy/lzy-servant.jar
ERROR: transport error 202: gethostbyname: unknown host
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [debugInit.c:750]

Solutions from stackoverflow like https://stackoverflow.com/questions/50344957/java-jdb-error-transport-error-202-gethostbyname-unknown-host doesn't help.

Hello!

Regarding the first problem: it seems that you have java 8 installed, but 17 is required. To install Java 17 run: apt install -y openjdk-17-jdk

BTW, in the next release we will remove java from dependencies.

Regarding the second problem: could you please show the contents of lzy_err.txt?

[mrMakaronka]

It seems that the issue was solved, so I am closing it.
