    Ubuntu 18.04 (LTS) Lxde Desktop Accepts the Password but Does Not Open

    Hello,
    2016 LTS I have updated Ubuntu and installed the 2018.04 LTS on it. I installed Lxde (Lubuntu) as desktop. At the opening, I always press a key to open the warning that even though I was using the computer to enter.
    When I couldn't open a rar file today, when I searched how to open a rar file in Ubuntu, I had a code like this and I loaded it and opened my rar file.
    Code:
    sudo apt-get install unrar
    When I try to turn my computer off and after a while, the group passes the screen and when the password screen comes up, I write the password on the screen, I press enter, the screen goes back to the password screen. I've tried many times, always coming to the same place. I have entered the wrong password a few times, again the same screen comes.
    The computer doesn't start.

    When I thought to the terminal screen with ctrl + alt + F1, I tried a few commands given above. When I enter my password and enter it, it first writes something like this.

    Ubuntu 18.04.2 LTS panda-Lenovo-3000-N500 tty1
    panda-Lenovo-3000-N500 login: _

    After a while, the top post goes to itself

    Login incorrect
    panda-Lenovo-3000-N500 login: _

    It is coming.

    somewhere it is said that
    you can use after the ctrl+alt+f1 to login the terminal, you can use that code
    Code:
    sudo rm -f .Xauthority
    i cant copy for that reason i dont know there is a gap between words.
    i worte that sudo _rm_-f_.Xauthority
    i use _ symbol as a gap. is it true? by the way it isnt work also this code

    At the login: prompt you should be entering your username instead you typed a command, but the password you provided was your password (but you tried to login to an invalid user account). The Login incorrect response is correct, as you didn't enter use the correct (or your) username

    fyi: the reason the error message isn't more clear is for security reasons - to provide fewer clues for hackers, so they don't know if the tried to login with a valid username or not.

    Re: Ubuntu 18.04 (LTS) Lxde Desktop Accepts the Password but Does Not Open

    [IMG][/IMG]I think my problem is that my disk space is full, can it be?When you enter the terminal with ctrl + alt + f1,after entering username + passwordI can write code.to thererespectively

    Code:
    sudo apt-get update
    sudo apt-get upgrade
    sudo update-grub
    sudo dpkg-reconfigure -a
    sudo apt-get install ubuntu-desktop
    sudo apt-get install ubuntu-desktop
    sudo apt-get install --reinstall ubuntu-session
    sudo apt-get install --reinstall ubuntu-desktop
    then I couldn't get it on the lines ... when I saw it didn't open in my experiments. Error writing to output file - there was no free space on the device (ip no)

    might the problem be due to any space in the disk? if it is, how i do free space at this point
    in the bottom line it is writen E: /var/cache/apt/archives/ there is no enough space"

    Please forgive me by my bad English!

    If your disk space is full, don't try and `sudo apt-get install` anything else as it just makes the problem (of lack of disk space) harder to resolve.

    The system has commands that can help, eg. `sudo apt-get autoclean` and `sudo apt autoremove` however they need space to run so if you ignored the space problem, you need to fix it before these can be run and help you.

    I wonder how much space you allocated to your file-system? The recommended is 25gb [for Ubuntu] which is fine for most users, however as I like adding software (esp. a second like you have done) I tend to allocate more than the minimum 25gb. Yes many users get along fine with less (but when you release-upgrade (ie. move from 16.04 LTS to 18.04 LTS) you tend to run into space problems.

    My recommendation is to firstly see how much space you have (you can paste it here, to look at my own system I used `df -hl |grep sda` (disk free, human format & local drives only then only display "sda" drives as i know that'll show my hdd, it may work for you, or you may need to use only `df -hl` (without the grep portion).

    If you get error messages (eg. before you typed in `sudo apt-get install --reinstall ubuntu-session` you had an error message that told you the next `apt-get install` would fail until you'd run the recommended fix. I suggest you read the messages before moving to the next command, if there are warning or error messages you don't understand, places like this forum are where you can get help, or given english is a second language for you, you could also try irc (https://wiki.ubuntu.com/IRC/ChannelList) where you may find a channel in your language/country.

    source: https://help.ubuntu.com/community/In...emRequirements for 25gb minimum disk
    (*there are some tiny sizes at the bottom for Lubuntu and Xubuntu, I'll endeavour to make them more realistic in the coming days*)
