shin's questions

When I create a file without a dot (hidden) and use gh, (Github cli), to create a gist, it works. But when I change it to a hidden file it fails to read a file.

# I can create a gist with a normal file.
shinichi@shinichi-Ubuntu:~$ gh gist create /home/shinichi/testing-gh

shinichi@shinichi-Ubuntu:~$ ls -al ~/testing-gh 
-rw-rw-r-- 1 shinichi shinichi 42 Jul 30 08:40 /home/shinichi/testing-gh

# Changing the file to a hidden one
shinichi@shinichi-Ubuntu:~$ mv testing-gh ./.testing-gh

# Creating a Gist fails
shinichi@shinichi-Ubuntu:~$ gh gist create /home/shinichi/.testing-gh
failed to collect files for posting: failed to read file /home/shinichi/.testing-gh: open /home/shinichi/.testing-gh: permission denied

# checking the permission
shinichi@shinichi-Ubuntu:~$ ls -al ~/.testing-gh 
-rw-rw-r-- 1 shinichi shinichi 42 Jul 30 08:40 /home/shinichi/.testing-gh

This works on macOS, but not Ubuntu. Why is it? How can I fix the problem? How can I make a dotfiles Gist on Ubuntu?

I installed Ubuntu 20.04 on MacBook.

I tried different thread of this problem, but I'm not able to solve the problem. How can I fix this problem so that I can use a camera with Skype.

When I set an output file in the home directory, the following curl command works. But when I use ~/.cache/mydir, it returns "Permission error".

$ ls -al ~/.cache/tera
drwxrwxr-x  2 shinichi shinichi 4096 Jul 28 09:04 .
drwx------ 16 shinichi shinichi 4096 Jul 27 20:52 ..
-rw-rw-r--  1 shinichi shinichi    0 Jul 28 09:04 radio_searches.json


$ curl -X POST -d tag=smooth http://all.api.radio-browser.info/json/stations/search -o $HOME/.cache/tera/radio_searches.json

curl: (23) Failure writing output to destination

Why I can output to a file in the home directory, but not in the ~/.cache/mydir.

Will there be data loss for upgrade?

I am thinking to update from 10.10 to 11.04.

Will any files or data be deleted?

Thanks in advance.

I just installed 10.10 on Dell, http://www.ubuntu.com/certification/hardware/201011-6891 along with Widows 7.

However it does not detect any wireless, so I am not able to connect to internet.

Wireless works on windows 7.

I have added my wireless connection but it does not work either. If I connect a cable, it works through Auto eth0.

What is wrong and how can I fix the problem?

Thanks in advance.

When I press Ctrl+Alt+F1 it goes to virtual terminal.

What is this virtual terminal for? When do you need to use it?
