Be helpful

Posts to pop_os must be helpful. When responding to a user asking for help, do not provide tongue-in-cheek responses like "RTM" or links to LMGTFY. Linking to direct sources that answer the asker's question is fine, but it's advised to provide some explanation as to how you got to that source.

Critique should be constructive

We within the Pop!_OS community welcome helpful criticism or ideas on ways to improve. However, basic "It's bad" or other simple negative comments don't help anyone fix anything. When voicing a complaint about something, try to point out ways the complaint could be improved or worked around, so that we can make a better product for it.

This rule applies to both Pop!_OS and its projects as well as other products available from third-parties.

Don't post malicious "advice"

It can be funny to joke about malicious commands, however this is not the venue for it. Do not advise users to run commands which will lock up their systems, steal their data, or erase their drive. Examples of this include (but are not limited to) fork bombs, rm, etc.

Posts violating this rule will be removed, even if the post is clearly in jest. Repeated offences may lead to a ban. You may understand that the command isn't serious, but a new user might not.

No personal attacks

Posts making a personal attack on any user will not be tolerated.

No hate speech

Hate speech of any kind will not be tolerated. Any violations will be removed, and are grounds for a ban.

can Pop! maintain supermin? (lemm.ee)

the maintainer is currently Ubuntu, but they stuck at version 5.2.1, which was released in Jan 2021. would Pop! compile a more updated version (say 5.3.1)?

zstd formated Kernel has conflicts with the 5.2.1, causing issues with libguestfs, but it's fixed upstream on 5.3.1+.

@[email protected], as of kernel 6.6.6, the supermin is working. Just wonder if the kernel is zstd compressed?

Install latest Pop OS with say kernel 6.5.6..

Install libguestfs-tools

running virt-sparsify gives the following error

Invalid ELF header magic: != \x7fELF insmod: init_module:virtio_snd.ko.zst: Invalid module format  
supermin: waiting another 1024000000 ns for root UUID to appear  
This usually means your kernel doesn't support virtio, or supermin was unable to load some kernel modules (see module loading messages above).

Below is my error from running libguestfs-test-tool (edit: with sudo)

'insmod: init_module: snd-timer.ko.zst: Invalid module format
