Cannot enable to Network before acctualization on ubuntu 20.4

sh flag

have I installed Synaptic and installed a few packages, not thinking if something may not work and everything was git but after restarting the system I can not connect to WiFi - there is "no WiFi adapters found" in bluetooth the same I am also unable to establish a network connection with a cable I plug it in and nothing happens Nothing appears on the network and I have no internet connection

I removed all installed packages from the history that I was going into the history of what I installed and removed everything except Bcmwl-kernel-source (I think it's his fault) Because I can't delete it

I tried Sudo apt-get purge - - auto-remove bcmwl-kernel-source Sudo apt install --reinstall bcmwl-kernel-source And in the package manager, but it is always there Error removing post-removal error code 127

I am completely green Please help

Sorry, I don't know English enough that I translated it on google

It is impossible to suggest anything. You installed and probably removed SOME packages. We can't guess what you did. The easiest way is to re-install.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
