[Linux]#1 problem in apt-get

apt-get install

I have problem with command using apt-get install in linux. what is worse is that fixing command(sudo dpkg --configure -a) doesn't work either. I had 3 different approach to solve this.

clay@4763e88da2a1:~/userdata/BeatlikeMichael$ sudo apt-get install locales
bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

deleting elements in following folders didn't help me

clay@4763e88da2a1:~$ sudo rm /var/lib/dpkg/lock-frontend

clay@4763e88da2a1:~$ sudo dpkg --configure -a

install Locales

I see. If you cannot install the locales package with sudo apt-get install locales, then you may need to try a different approach. You could try manually downloading the package from the Ubuntu package archives and installing it using dpkg. Here are the steps you can follow:

1. Go to the Ubuntu package archives for the locales package by visiting the link https://packages.ubuntu.com/focal/locales (assuming you are using Ubuntu Focal Fossa version)
2. Under "Download locales", choose your architecture and click on a nearby mirror to download the .deb file to your computer.
3. Once the download is complete, navigate to the directory where the file was saved (e.g., cd ~/Downloads) and run sudo dpkg -i locales_*.deb to install the package. If dpkg reports any unmet dependencies, you can try to resolve them by running sudo apt-get install -f to install any missing packages.
   
   
   
   

dialog

I installed locales and set my locale with english but it didn't help me. So I tried to install dialog which could be a key to solve "sudo dpkg --configure -a". But it didn't work either.

clay@4763e88da2a1:~/userdata/BeatlikeMichael$ sudo dpkg --configure -a
Setting up openssh-server (1:8.2p1-4ubuntu0.5) ...
debconf: unable to initialize frontend: Dialog
debconf: (No usable dialog-like program is installed, so the dialog based frontend cannot be used. at /usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 76.)

deleting openssh-server

sudo dpkg --remove openssh-server

clay@4763e88da2a1:~/userdata/BeatlikeMichael$ dpkg -l | grep openssh-server
rF  openssh-server                          1:8.2p1-4ubuntu0.5                amd64        secure shell (SSH) server, for secure access from remote machines

The status "rF" indicates that the package is marked for removal, but there are still files associated with it that have been marked for purging.

sudo dpkg --remove --force-remove-reinstreq openssh-server

sudo dpkg -P openssh-server

clay@4763e88da2a1:~/userdata/BeatlikeMichael$ dpkg -l | grep openssh-server
pF  openssh-server                          1:8.2p1-4ubuntu0.5                amd64        secure shell (SSH) server, for secure access from remote machines

This command will remove the package openssh-server forcefully even if it is marked for reinstallation.
The "-P" option will remove the package, as well as its configuration files, which may help resolve the issue.

solved

after I removed openssh-server, sudo apt-get install command started to work. But I don't understand the reason.
