Pi4 : No desktop, only command line (perhaps because of the installation of Git ?)

[briere]

Hello,

I intalled Git yesterday on my Raspberry Pi 4B.

After having done "sudo apt update" and "sudo apt full-upgrade" (and having then rebooted the Raspberry), I wrote "sudo apt install git-all"

But then :

• When I was clicking on the shortcut of the document browser from the taskbar, an error message was displayed, explaining that the folder menu "Accessories/pcmanfm.desktop" was invalid. (It was displayed in French, since I use may Raspebrry in French)
• When I was clicking on the shortcut to access the terminal from the taskbar, an error message was displayed, explaining that the folder menu "Accessories/lxterminal.desktop" was invalid.

When I tried to shutdown the Raspberry, nothing happened when I clicked on shutdown or reboot (what I used to do), so I wrote in the terminal "sudo shutdown -h now" (and it worked).


When I switched on the Raspberry today, it asked me for my login and my password and, from then on :

• I only have a command line (the desktop was never displayed). I rebooted it, I even entered "sudo shutdown -h now" and then unplugged it, but I always get the same terminal.
• When I enter "startx", il replies (among others) "unable to connect to x server: connection refused".
• When I try "df -h", it doesn't seem to be full (the maximum percentage of use in the list is 21%)

.

In case it would be useful : "uname -a" leads to "Linux raspberrypi 4.19.97-v71".

Do you have any idea of what happened and how I could solve it ?

Hello,

I installed Git yesterday on my Raspberry Pi 4B.

After having done "sudo apt update" and "sudo apt full-upgrade" (and having then rebooted the Raspberry), I wrote "sudo apt install git-all"
...

git is already installed within Raspbian (desktop/full versions, not sure about lite) so why run sudo apt install git-all" ?
According to synaptic (a gui package manager) git-all is a dummy package:

Code: Select all

fast, scalable, distributed revision control system (all subpackages)
  
Git is popular version control system designed to handle very large
 projects with speed and efficiency; it is used for many high profile
open source projects, most notably the Linux kernel.

Git falls in the category of distributed source code management tools.
Every Git working directory is a full-fledged repository with full
revision tracking capabilities, not dependent on network access or a
central server.

This is a dummy package which brings in all subpackages.

Just wondering if you're following some old/inappropriate instructions that included something else that's caused your issues?

Thank you for your quick reply.

I am a beginner with Raspberry Pi and I just followed the instructions I found there https://git-scm.com/book/en/v2/Getting- ... alling-Git (and on some other websites), but I perhaps did not realize that the instructions were not appropriate to my situation...

To be more precise, I just followed the folllowing part of the link cited in my last message :

If you’re on a Debian-based distribution, such as Ubuntu, try apt:
$ sudo apt install git-all

Then I configured my name and email with "git config --global" (without any problem).

Don't try to install git-all. It pulls in a huge list of packages and some of them like initscripts will badly break your Raspbian install. Easiest "fix" is to reinstall a fresh image. Otherwise you'll need to manually reverse all the changes.

git-all has a recommended dependency that wants sysvinit but sysvinit and systemd can't both be installed so apt goes ahead and uninstalls systemd along with everything that requires it so it can install sysvinit.

You might get away with looking in apt's log to find out which packages were removed when you asked it to install git-all and reinstall them. See posts from this thread for details.

To be more precise, I just followed the folllowing part of the link cited in my last message :

If you’re on a Debian-based distribution, such as Ubuntu, try apt:
$ sudo apt install git-all

Then I configured my name and email with "git config --global" (without any problem).

I suspect that's associated ("only necessary") if you intend to set up a git repository that others might access. (The parts of) git already installed are sufficient to access (clone) existing repositories AFAIK. Personally, because I'm, perhaps a "tad old-fashioned", and it's what I've used historically, I tend to simply use RCS/CVS and GNU autoconf, automake etc. methods to version control/distribute my demo. codes in traditional tarballs eg. see: https://www.cpmspectrepi.uk/raspberry_p ... tware.html
and https://www.cpmspectrepi.uk/raspberry_p ... cking.html
Git, and similar approaches are, perhaps, more suited to multi-author/contributor software management, especially "over the web"

[Edit] Whilst writing the above I see others have posted explanations about what has probably been broken by the git-all install.

[briere]

Thank you very much for your help and your explanations !
According to the logs, what is described in the thread you mentioned seems to be exactly what happened to me... I reinstalled the removed packages which had not already been automatically installed and I got my dekstop back ! While reinstalling them, I had many "Error: Timeout was reached" but I could re-run the commands, so I think (and hope) all went well.

The first time I tried I still had the "Accessories/pcmanfm.desktop was invalid" and "Accessories/lxterminal.desktop was invalid "problems mentioned in my first message (about the shortcuts of the taskbar), but then it returned to normal without me doing anything.

Thank you so much !!
