Black Chase's questions

I accidentally removed python from /usr/bin as it was conflicting with /usr/local/bin. (rm -rf /usr/bin/python*)

After realising my mistake i reinstall python3.8 and python2.7 from source. Python is now working.

I took some of the help from here.

OS: Ubuntu 20.04, with KDE, ZSH

But whenever i try to install any other package via apt this happens:

Setting up mercurial-common (5.3.1-1ubuntu1) ...

Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)

I tried sudo dpkg --configure -a which resulted in:

I am not able to install any package from apt because of this and i am not able to configure mercurial.

I tried downloading mercurial-common's .deb and installing it as it was on ubuntu:

$ apt-get download mercurial-common
$ sudo dpkg -i mercurial-common_5.3.1-1ubuntu1_all.deb
(Reading database ... 564985 files and directories currently installed.)

As asked i tried:

cd /var/cache/apt/archives/ && sudo rm -rf *.deb
sudo apt --purge autoremove mercurial\*

(I am using zsh, so mercurial* wont work), resulted in:

I need Cuda 10.1, for PyTorch, TensorFlow, and MatLab. They don't support Cuda 11. I also need steam to play games. Is there any way I can use Cuda's parallel processing while able to play games on steam. Please help.

Steam requires libnvidia-gl-440:i386.

The following packages have unmet dependencies:
libnvidia-gl-440:i386 : Depends: libnvidia-gl-450:i386 but it is not going to be installed

But installing libnvidia-gl-450:i386, says:

The following packages will be REMOVED:
cuda-10-1 cuda-demo-suite-10-1 cuda-drivers cuda-drivers-450 cuda-runtime-10-1 libnvidia-compute-450 libnvidia-decode-450 libnvidia-encode-450 libnvidia-gl-450 libnvidia-ifr1-450 nvidia-compute-utils-450 nvidia-driver-450 nvidia-utils-450

Tried links: Steam won't launch on Ubuntu 18.04 Steam not working on Ubuntu 20.04 but didn't help with Cuda and steam both at the same time.

Edit:

It's not only with steam, it won't allow me to use any other 32-bit application. Installing libnvidia-gl-450:i386 asks to remove Cuda 10.1 which I can not.

I am looking for a way to run Cuda, as well as use all the 32-bit arch applications. As stated above Matlab, Pytorch, TensorFlow do not support Cuda 11.

Steam's client is still 32-bit. Ubuntu 20.04 has now removed 32bit arch support. Cannot install lib32bz2-1.0. Steam is not running.

I have Nvidia 2060, it is working fine, even with CUDA. When I was on 18.04, I was playing CS:GO. And now steam/CS:GO won't open.

After upgrading to Ubuntu 19.04

[ OK ] Started GRUB failed
[ 145.200501] ucsi_ccg 0-0008: ucsi_ccg_init failed - -110

Tried recovery mode, what happened is in the pic attached. Supposedly due to some the graphic card (CUDA) issue. (This happened after gnome settings were not opening, so I restarted)

Link of AskUbuntu thread: Gnome Settings not opening

Asked again on: https://unix.stackexchange.com/questions/550422/ucsi-ccg-init-failed-110

Need help ;_;

gnome-control-center 

in terminal is giving

Segmentation fault (core dumped)

And settings is not starting at all, just loading forever.

All this happened after I upgraded to Ubuntu 19.04

Edit: After a restart, now the OS is not loading. Supposedly kernel is screwed.
