Gentoo december issues
Dear diary, today I booted up my computer with Gentoo as I wanted to update the kernel and others packages; however when I wanted to update the kernel source code there was a lot of dependencies for only the Linux kernel —It is kinda surprisingly—:
As usual, ICU was blocking my updates and tries of packages installations, also it seemed that ncurses was blocking the update too (I hadn’t seen this before)
However, because I updated my mesa drivers, Gentoo was luckily unlocked as it upgraded 108 packages.
Finally I had another problem with Ruby and Python because Gentoo was using the old versions, so I removed them as this topic suggested:
LinkAlso I learned a very useful trick about the console, how to avoid that the shell logs an specific command, just add this to your ~/.bashrc file and that’s all.
HISTCONTROL="ignorespace"
So when you do not want Linux to log a command just type an space before the command and after the prompt, and ready!
Recoloring icons to pink
I am still using Linux Deepin, I found it interesting that Linux Deepin includes the Flattr icons by default, however the folder icons are green and It didn’t combined at all, I wanted them to be pink, and so for the first time I achieved to automatically change the colors using a command:
Original icons:
Updated icons
cd /usr/share/icons/flattr/places/64/
sudo for p in folder* ; do convert "$p" +level-colors red, "$p" ; done
cd /usr/share/icons/flattr/places/16
sudo for p in folder* ; do convert "$p" +level-colors red, "$p" ; done
Explanation:
The system icons location is /usr/share/icons/flattr , in the places subfolder is located all folders icons wich are available in two different sizes: 16×16 and 64×64. Thus /usr/share/icons/flattr/places/64/ stands for 64×64 sized icons and /usr/share/icons/flattr/places/16 stands for 16×16 icons.
As them are system locations we need to use sudo; in the second and forth line the color of icons are changed from green to pink with the execution of a loop, i.e. using the for command. The for command syntax is similar to this: for a variable in a string ; do something, done ; our variable of course is the letter p and our string is the regex folder* ; our something are the special commands for transform the pictures:
Convert is the cli of the well-know image-magick, the following is the command used for transform each picture:
Trying Linux Deeping
Today was a very funny and exhausting day. I deleted my Arch Linux installation and :c it brought me back nostalgic memories:
To tell you the truth I wanted a simpler Linux distribution so that I could be focused on Gentoo because Arch is also a complex Linux distro.
I tried to install Ubuntu with debootstrap but surprisingly I failed :c , you could say it is surprisingly since I am able to install Gentoo but not so Ubuntu. I was able to install the core system and make chroot, also I was able to install everything with no problems.
The issue was that Ubuntu booted into emergency mode, despite of realizing I had forgotten to add the file system in fstab, fixing it didn’t solved the problem.
The most important thing is that I learned that we have to be careful when using bootstrap to install a distribution and make a list of steps or diagram.
And my main mistake was to forgot the fact that Ubuntu have several repositories D: I was indeed overconfident, it it hard to me to understand how was I able to flawlessly install Debian Sid in the same fashion, Arch and of course Gentoo and failed with Ubuntu :c
Maybe systemd is not enough stable in Ubuntu yet, by the other hand I learned a new concept UTMP, is a kind of special file where every login is recorded. It depends in the symlink in /var/run of /run
Possibly it had to do the improperly unmounting of LVM partitions in Gentoo, now I remember once Arch did not let me boot into until I runned fsck, well, never mind.
What a troublesome init system is this systemd. It seems that getting back to Openrc right in Gentoo was a very wise decision ^o^
After failing to install Ubuntu I tried to install Deepin and it was perfect, it is gorgeous, my dream Linux distro
imageAnd now guess what, I also installed deepin in the cli way, to tell you the truth I wanted to do it using a usb flash but I wonder where my pen drive is :c , anyway.
The most challenging thing was to set up the root password, I didn’t know what I was not able to set the root password within chroot, I had to boot with a kernel parameter (init=/bin/bash) in order to set up the root password and so my local user password.
I think it is perfection
imageAnd finally I did a backup of my root file-system using the following command:
zsh.li/c/backup-root
This will create a tar.7z highly compressed file, I choosed the 7z method since it supports multi-thread compressing -I have 8 threads-, and for the sake of time saving
Public backup of blog
Today I learned how to connect via ftp with my remote hosting and wget ended being perfect while curlftpfs was really bad :c
Today I installed Apache, PHP and set up a WordPress local server to have a backup of my Linux website, also to be able to make this kind of backups.
I think it is very important to make different kinds of backups because it is possible that even the most reasonable and useful backup can fail at the moment.
