From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

how do I enable wlan as root from initramfs? (lemmy.ml)

upgrading xubuntu 23.10 to 24.04.

I purged a broken package that was blocking upgrades with sudo dpkg -P libfreerdp2-2 and immediately afterwards I executed sudo apt get upgrade. It unleashed a list of 96 packages to upgrade totaling 900 MB of data.

However, if I press yes on ‘do you want to continue?’ ~~wlan is off~~ wlan is on, nmtui clearly shows it activated, but each time I try upgrading, updating, autoremoving, or install --fix-missing I get:

E: failed to fetch http… initramfs-tools-core… could not connect to 127.0.0.1, connection refused.

(I can write the whole address if you need it)

Some other contributors suggest I use a live usb, not installing the OS but using the live usb with working wlan to complete the installation, but this seems to be more complicated than working directly from initramfs.

i think you have to start the service that configures your network. maybe you have to load the kernel module for the wifi adapter before that, idk.

however, it's weird you have to do this from initramfs . why doesn't it boot further?

also, shouldn't there be the old kernel and old initramfs from before the upgrade still available in your boot manager to choose somehow after the BIOS is done?

Small breakthrough: I booted the system without problems to tty1 (I believe this is called single user mode), logged in as an old user and now I can see all my data, logged in as old me. Do you still recommend to backup from live usb and upgrade from there?

NMTUI shows that wlan works

me? i didn't recommend that. if you have your wifi, you could update now. however, if you don't have a backup yet, you should 100% make one. i always make fresh backups before a dist upgrade. (everyone hates the way I'm doing it, but it works really well. i just tar every important fs with --one-file-system on a 1TB USB stick. if they don't break at writing, they will be able to store the data much longer than i would need.) meaning, in your situation I would already have one and it sounds like you forgot that step, but idk.
