Maybe flatpak issue...

What is compatible with? With Devuan?

Be creative ! Try search

apt search theme | less

No.

Yes.

The main problem I can think of is that that command will set the execute bit on all files, even those that aren’t executable.  So, if you have a file called foo, and someday you want to do cat foo or print foo and you accidentally type just foo, the shell will try to execute foo; i.e., interpret it as a shell script. 

This will probably just explode in your face harmlessly, but if foo contains anything that looks like a shell command, you could get harmful results.

A lesser issue is that if you have a file that you want to preserve, and last year you did a

chmod 444

to protect it from yourself,

the chmod 700

will restore your write bit, and make it easier for you to clobber the file accidentally.

The solution to both issues is to do

chmod go= -R ~

or

chmod go-rwx -R ~

which will turn off all bits for group and others, but leave your access alone.

Hello.

Please, check, maybe this dir (.themes) already exist.

Open a terminal and type

ls -a

If this dir does not exist, create this dir with command:

$ mkdir .themes

You can search for the gtk3 themes with simple command:

$ apt search gtk3 | less

You can scroll up or down with arrow keys.

Using this method, you will easily find the gtk 3 theme you need.

For example, if I want to install

darkfire-gtk-theme

the following commands must be used:

sudo apt update

sudo apt install darkfire-gtk-theme

Hello.

Please, open the terminal and type in terminal

chromium

Chromium should launch. If not, paste terminal output here.

Same procedure valid for firefox-esr.

Hello.

According this https://www.devuan.org/get-devuan info, server cd sets contains:

(~670 MB): CD1 of a 4 CD set that allows for a complete off-line server/minimal installation. The remaining CDs offer several desktop choices and a limited selection of additional software.

CD2: Xfce (installable from tasksel) and LXDE.
CD3: MATE (installable from tasksel) and Openbox window manager.
CD4: Cinnamon (installable from tasksel) but requires CD2 and CD3 to install.

I found a much simpler way to avoid this problem with

nvidia-persistenced

Since this package is not needed by many, the easy way is as follows.

1. Install the required nvidia driver (in my case, the driver I need is nvidia-tesla-470-driver, because my video card does not support a higher version driver), using the command

sudo apt install --no-install-recommends

The list of recommended packages includes the

nvidia-settings-tesla-470

package, which can be installed with the simple command

sudo apt install nvidia-settings-tesla-470

Using this method avoids installing the nvidia-persistenced package.

I was running FreeBSD 13.2 on one of the machines, but I decided to switch to Devuan, because FreeBSD was using more power and running hotter. And with Devuan there is no such problem...

Hello. Please, fix your web site, because when I try to enter your website, the firefox browser says that secure access is not possible. The browser prompts you to go to a website that uses the http protocol. Which is not good from a security point of view

Default configuration of Devuan package repositories looks like this

deb http://deb.devuan.org/merged daedalus          main contrib non-free non-free-firmware
