Can't write to brand new drive?

DiogenesOfMiami

I've decided to make the plunge into Kubuntu in lieu of "upgrading" to Windows 10/11 with very little experience with Linux, and I've run into trouble quite early.

In short, I want to use this as my main PC from which I stream Steam games, among other things.

Everything was going swimmingly with my install until it came time to make a new Steam Library folder on my secondary NVMe drive. I tried creating a folder with Steam and it gave me an error that the drive was read-only.

I thought surely Steam must be bugged, so I went to make the folder myself via the Kubuntu GUI. Nope, read only. Mind you this is on a fresh install, brand new drive I just mounted as ext4 for maximum compatibility with Steam. Steam will let me install stuff on my primary drive just fine, but neither it nor I can create a new folder via GUI on nvme0n1.

I've done unmounting, remounting, via command line terminal and GUI (via KDE Partition Manager), and I'm becoming very frustrated. Here's the results from some commands I found were commonly asked about in similar questions:

For the record, I have no idea what those tons of /dev/loop#s are, but from a cursory web search it doesn't seem like they're likely to be the culprit.

I also don't understand why Linux/Kubuntu apparently mounted a third, virtual drive in the form of /dev/mapper/vgkubuntu-root, but I'm sure it's perfectly logical to someone who has any idea what they're doing, unlike myself. I made the plunge into Linux without so much as learning the difference between /dev/ and /root/ and such, which believe me I plan to learn in the next few hours/days.

For now... if you would kindly help me just get a big ol' game installed on /nvme1n1, I'd very much appreciate it.

Still can't create a new folder in that partition. The option is greyed out if I right-click to "create new," and when I went into Properties->Permissions->Advanced Permissions for the new partition, it has a table like so:

| Type | Name | r | w | x | Effective |

| ---- | ---- | - | - | - | --------- |

| Owner | | X | X | X | rwx |

| Owning Group | | X | | X | r-x|

| Others | | X | | X | r-x |

I'd avoid the volume group/logical volume complication unless you really need it (raid, encryption). Then understand the difference between a disk (/dev/nvme1n1) and a partition (/dev/nvme1n1p1). Partitions get filessytem made on them, get mounted, and get checked, not disks.

Loop devices are from snaps. I do not allows snaps on my Kubuntu system and have not missed anything yet. Had to convert Firefox. You are not showing any partitions on nvme1n1?? You need to create at least one partition, format to ext4 (or other Linux format) and give yourself ownership & permissions to that partition(s). I prefer not to totally use entire drive initially with my partitions for future changes, but that is a user preference. Use gparted to create partition(s), It already looks like gpt which is good. Gparted will also format it.

@ubfan1 I'm definitely not using RAID, I just did mostly default options for a fresh Kubuntu install. Not entirely sure what volume grouping is, to be honest. I can try to figure out how to disable it if you think it'll help!

@oldfred I don't know how to forbid snaps and I don't know what enabled/uses them on this brand spankin' new Kubuntu install. After reading your comment I realized the last step I did before coming here for help was in fact clearing out the partition. I'll try to figure out how to give myself permissions when I try making one again momentarily.

One way to use a data partition(s). https://askubuntu.com/questions/1013677/storing-data-on-second-hdd-mounting & https://askubuntu.com/questions/1058756/installing-all-applications-on-a-ssd-disk-and-putting-all-files-on-hdd-disk Back with XP, I had two, one NTFS for any data I wanted in both systems and one for Linux. I now have one data and one photos only as that grow so much & continues to grow the most. Something about grandkids. You can see snaps: `snap list` and convert Firefox: https://www.omgubuntu.co.uk/2022/04/how-to-install-firefox-deb-apt-ubuntu-22-04

Thank you for the links @oldfred; I have some reading to do, and at a cursory glance they seem very similar to the issue(s) I've got going on so they will likely be extremely helpful.

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.
