#### Search for Brave desktop icons, and remove them:
|
|
|
|
|
```
|
|
|
|
|
grep -L -i 'thing-inside-the-file' $(fd -H "^brave-(.*)-default\.desktop" ~)|xargs rm
|
|
|
|
|
```
|
|
|
|
|
This is because between Brave and Gnome, various duplicates get stored all over the place. eg:
|
|
|
|
|
```
|
|
|
|
|
gmgauthier@plato $ grep -L -i 'youtube' $(fd -0 -H "^brave-(.*)-default\.desktop" ~)
|
|
|

|

## Fixing apt keys after a manual gnupg upgrade
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
sudo apt reinstall gpg
|
|
|
|
|
which gpg
|
|
|
|
|
/usr/local/bin/gpg
|
|
|
|
|
sudo ldconfig /usr/local/bin/gpg
|
|
|
|
|
sudo apt update
|
|
|
|
|
gpg --version
|
|
|
|
|
```
|
|
|
|
|
The "reinstall" in the first command won't actually break your fresh install. when you run the version, it will still report your new version.
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
gmgauthier@plato $ sudo apt reinstall gpg
|
|
|
