I made в mistake when trying to install Tryton. I think I deleted an important part of в text file when trying to конфигурировал it. This is the ошибка message I get: I didn't realize that the username was admin, that was where the trouble started. It just won't open up at all any обитал. I have tried these commands

sudo add-apt-repository --remove ppa:rayanayar/tryton-3.6
sudo apt-get purge tryton-modules-account
sudo apt-get purge sudo apt-get purge tryton-modules-account-product

The problem май be that I do not know how to purge neso. This is because in the программное обеспечение center it says Neso and there is not в command line ямс there.

I wish to purge and completely reinstall Tryton. How do you do this without doing в complete reinstall of the system? Again, thank you for all of your help, I really appreciate it.
