[SOLVED] E: Problem executing scripts APT::Update::Post-Invoke

If you have a legacy docker version and you try to update you repositories with apt update, probably you will get the following error: E: Problem executing scripts APT::Update::Post-Invoke 'rm -f /var/cache/apt/archives/*.deb /var/cache/apt/archives/partial/*.deb /var/cache/apt/*.bin || true' E: Sub-process returned an error code To solve it, you must install a version higher than 20.10.9. If you haven't this version in you apt repositories, you can install it throught snap. To check your docker version just write this command: docker -v  Enjoy it!

[Solved] Interface *mon is too long for linux so it will be renamed to the old style (wlan#) name.

If you tried to start monitor mode in a wireless interface, probably you will see the following message: Interface wlx6466b31e7738mon is too long for linux so it will be renamed to the old style (wlan#) name.  , where 6466b31e7738 is the MAC address from your interface.  Just write the following commands in your terminal: sudo ifconfig wlx6466b31e7737 down sudo ip link set wlx6466b31e7737 name wlan0 sudo ifconfig wlan0 up , where wlx6466b31e7737 is your wireless interface. Now, you could start monitor mode in your interface as follows: sudo airmon-ng start wlan0 Found 4 processes that could cause trouble. Kill them using 'airmon-ng check kill' before putting the card in monitor mode, they will interfere by changing channels and sometimes putting the interface back in managed mode     PID Name    1382 avahi-daemon    1388 NetworkManager    1424 wpa_supplicant    1427 avahi-daemon PHY    Interface  ...

[Solved] Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

 If you run apt update, you probably will see the following message: [Solved] Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details. To solve it, you need to export the GPG key from the deprecated keyring and store it in /usr/share/keyrings. To do it, just get the last 4 bytes from the fingerprint and export the key to /usr/share/keyrings folder: sudo apt-key list Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)). /etc/apt/trusted.gpg -------------------- pub   rsa4096 2018-08-14 [SC]       E869 7E2E EF76 C02D 3A63  3277 8881 B2A8 2109 76F2 uid           [ unknown] Package Manager (Package Signing Key) <packages@pgadmin.org> sub   rsa4096 2018-08-14 [E]  sudo apt-key export 210976F2 | sudo gpg --dearmour -o /usr/share/keyrings/pgadmin4.gpg   Now, you need ...
