htop-snap's Introduction

This is the snap for htop, an interactive process viewer.
It works on Ubuntu, Fedora, Debian, and other major Linux distributions.

Command-line Installation

sudo snap install htop

(Don't have snapd installed?)

That'll install the latest stable release of htop.

Or, if you're feeling adventurous, try the Launchpad autobuilds for the next major release from the edge channel:

sudo snap install htop --edge

Permissions (optional)

Once installed, this snap can optionally be connected to some extra plugs:

sudo snap connect htop:mount-observe
sudo snap connect htop:network-control  # DELAYACCT support

htop-snap's Issues

htop won't work with kitty

Kitty is currently not available as a snap so I cannot install it with snap. Kitty via apt and htop via apt work fine but Kitty via apt and htop via snap does not.

htoprc is not being loaded/saved

When you run htop and change the settings using F2 and quit, the settings are not saved, so that subsequent uses of htop have default settings.

When I run using the full path:

/snap/htop/current/usr/local/bin/htop

the settings are correctly loaded from ~/.config/htop/htoprc. So I suspect this has something to do with the wrapper script mentioned in #2.

This is using the htop 3.0.5 snap.

I/O tab shows N/A on fresh install of Ubuntu/Debian (any version, e.g. Ubuntu 22.04, Debian 11). I've connected all plugs. I see no errors in syslog from apparmor. There is no this issue on CentOS snap. Same issue has other users too (#18).

May be this is related, but I see this not every time:

WARNING: cannot create user data directory

Hi! First, thank for snaping this!

I'm using Ubuntu Core in a Intel NUC board. Ubuntu Core 18 was installed on the internal eMMC storage (https://www.ubuntu.com/download/iot/intel-nuc).

Once Htop Snap is intalled, I run this command: 'htop' and there is a warning:

2019/01/12 15:40:34.496324 cmd_run.go:835: WARNING: cannot create user data directory: cannot create "/home/iotcomm/snap/htop/1066": mkdir /home/iotcomm/snap: no space left on device cannot create user data directory: /home/iotcomm/snap/htop/1066: No space left on device

Best regards.

ENV lost when executing htop

I think that something is wrong with the ENV when executing htop, because, for example, when I choose the "Tree" view, the "lines" are drawn using ASCII:

But if I execute the binary directly, like this:

$ /snap/htop/current/bin/htop

UTF-8 characters are used:

cannot create user data directory: /home/bost/snap/htop/1168: Not a directory

$ sudo snap install htop
htop 2.2.0 from Maximiliano Bertacchini (maxiberta) installed
$ htop
cannot create user data directory: /home/bost/snap/htop/1168: Not a directory

Installation using apt sudo apt install --yes htop works flawlessly.

`man htop` return nothing for htop installed as snap

Steps to reproduce:

Have Ubuntu 20.04 LTS installed, without deb-version of htop
Run snap install htop, wait it to finish
Run man htop

Expected results:

man htop shows man-page

Actual results:

man htop does not show man-page

Bug at launchpad: https://bugs.launchpad.net/ubuntu/+source/snap/+bug/1910790 .

App armor denies access to `/proc/spl/kstat/zfs/arcstats`

I've installed htop version 3.0.5 and am running into the issue that htop is not able to access /proc/spl/kstat/zfs/arcstats.

This is an excerpt from the syslog:

[42062.241628] audit: type=1400 audit(1616518163.683:3498): apparmor="DENIED" operation="open" profile="snap.htop.htop" name="/proc/spl/kstat/zfs/arcstats" pid=872438 comm="htop" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0

The effect is also noticeable within the interface, where all ZFS ARC related meters are disfunctional.

htop 3.0.5 snap returns error message when starting.

The following error message is returned:
Error: File /etc/sensors3.conf: Permission denied

The application starts allright, but still drops the error message.

The file /etc/sensors3.conf is owned by root as expected.
Output of snap version:

The apt/deb version of htop 3.0.5 works without issue.

Hello,

how to avoid log spam ?

i remove snap and choose apt version 😮‍💨

Htop is dead, long live htop-dev

The htop project is being maintained by @htop-dev - https://github.com/htop-dev/htop could the snap be moved to this one and reflect the 3.0.0 release?

Incompatible htop license change

Hi @maxiberta - you've listed this github repository as MIT licensed and it performs a build of the htop sources. The htop sources are made available under the GPLv2 license, which is incompatible with the MIT license. Derivative works based on GPLv2 licensed works are again subject to being licensed under the GPLv2. Could you update the license on this repository accordingly please?

References: https://en.wikipedia.org/wiki/GNU_General_Public_License#Compatibility_and_multi-licensing

Many thanks!

-- BenBE (on behalf of the htop maintainers)

Delay stats not available

Delay stats like PERCENT_CPU_DELAY, PERCENT_IO_DELAY, PERCENT_SWAP_DELAY are not available as columns in the htop snap.
From the documentation, it seems CAP_NET_ADMIN is needed, so it should be just a matter of adding a plug for the network-control interface to the snap.

Can't lsof of processes

Hi! First, thank for snaping this!

Second: I've seen that when I try to list the open files of a process (using 'l') I get this message:

Could not execute 'lsof'. Please make sure it is available in your $PATH.

I guess the solution would be as easy as adding lsof to the stage-packages, but I'm not sure.

Thanks again!
