Okay, tried to update armory through the .deb file 13.10.
I'm running Linux Mint 16 petra.
it gave me an error and told me I had to run sudo apt-get install -f from the terminal.
It wouldn't let me open a terminal window, so I restarted the system.
Instead of booting to the Linux Mint logon screen, it now gives me the Ubuntu 13.10 startup screen but never gets to logon.
I went into linux mint recovery and did the sudo apt0get install -f from there, but rebooting the system still gives me a stuck screen that shows ubuntu 13.10.
Any ideas?
I would guess (just a guess though) that something was messed up before you installed the new .deb, and that installing the .deb triggered something. In other words, it seems unlikely that this is an Armory issue...
I don't know much about desktop environments/X on Linux, but maybe this will help. After booting, switch to a terminal screen with Ctrl-Alt-F1 and log in. Take a look inside these logs to look for anything suspicious:
less /var/log/syslog
less /var/log/boot.log
less /var/log/Xorg.0.log
Like I said, I probably can't help, maybe someone else here can... my honest opinion: you're probably better off seeking support in a Mint or Ubuntu forum.
