Anaconda error, no explanation
by Geoffrey Leach 20 Apr '20

20 Apr '20

I'm installing Fedora 30 on a system that has an existing linux installation. It is my intention to replace the existing linux. I'm using custom partitioning. When exiting the custom partitioning page (click Done) it says that there's an error, but does not elaborate. A second click on done gives me a summary page with three errors (ext4 partitions) and no explanation. On the installation summary page, "begin installation" is not enabled. FWIW, the boot loader is UEFI Thoughts? Advice?

Alpine curiosity
by AV 20 Apr '20

20 Apr '20

I have been a longtime user of mutt but switched to evolution and/of geary to have less configuration hassle. Yesterday I had an hour to spare so I decided to have a look at the Alpine email client. I installed and did a minimal config only adding imap, smtp and sender. No password. Out of curiosity I tried to send myself an email (to 'volovics(a)ziggo.nl') expecting Alpine to ask for my password. To my surprise it looked like the mail got sent without password. Indeed a few minutes later I received it in evolution. Evolution is my default email client on this laptop. Could Alpine have used the password encoded by evolution? I can't find any comprehensive documentation on the working of alpine and don't feel like digging into alpine internals because I am not going to use it. Maybe somebody with alpine knowledge can explain. AV

dnf question
by David 19 Apr '20

19 Apr '20

There is a poster on Reddit criticizing dnf as being too slow. I do not use Reddit. But here is my question. The terminal emulator is running in wayland. Right ? So is it fair to compare that to a distro or DE not using wayland ? Obviously, I have no clue what I am talking about. Also, if dnf speed is important to you, should you not reduce unnecessary processes or do it in the tty ? D.L.

netfsname: command not found
by Hiisi 19 Apr '20

19 Apr '20

Hello, list. After compiling some ancient Fortran project I'm unable to run the resulting binary. It halts with the following message: netfsname: command not found Searching with dnf I wasn't able to get any matches. I understand it must be some old commands, but maybe grey-headed folks here could point me into the right direction? -- Hiisi. Registered Linux User #487982.

SELinux is blocking hibernate
by Sreyan Chakravarty 19 Apr '20

19 Apr '20

I have just configured a 8GB swap file on my Fedora 31 laptop. But it seems that SELinux is blocking access to the swap file. SELinux is preventing systemd-sleep from read access on the file fedora.swap. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that systemd-sleep should be allowed read access on the fedora.swap file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'systemd-sleep' --raw | audit2allow -M my-systemdsleep # semodule -X 300 -i my-systemdsleep.pp Additional Information: Source Context system_u:system_r:init_t:s0 Target Context unconfined_u:object_r:swapfile_t:s0 Target Objects fedora.swap [ file ] Source systemd-sleep Source Path systemd-sleep Port <Unknown> Host localhost.HPNotebook Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-3.14.4-50.fc31.noarch Local Policy RPM selinux-policy-targeted-3.14.4-50.fc31.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name localhost.HPNotebook Platform Linux localhost.HPNotebook 5.5.15-200.fc31.x86_64 #1 SMP Thu Apr 2 19:16:17 UTC 2020 x86_64 x86_64 Alert Count 1 First Seen 2020-04-13 21:12:22 IST Last Seen 2020-04-13 21:12:22 IST Local ID 39955636-b570-49ae-9286-ae92b49dc1c7 Raw Audit Messages type=AVC msg=audit(1586792542.56:418): avc: denied { read } for pid=5603 comm="systemd-sleep" name="fedora.swap" dev="dm-1" ino=13 scontext=system_u:system_r:init_t:s0 tcontext=unconfined_u:object_r:swapfile_t:s0 tclass=file permissive=0 Hash: systemd-sleep,init_t,swapfile_t,file,read -- The above is the message I got from the SELinux trouble shooter.

Old GCC versions
by Hiisi 18 Apr '20

18 Apr '20

Hello, list! Back in the day, Fedora had compat-gcc in repos. I can't find it any longer. How do I install older versions of GCCC now? Say, I need GCC 4.6. What's the best way of getting it on Fedora 31? -- Hiisi. Registered Linux User #487982. Be counted at: https://linuxcounter.net/ -- Spandex is a privilege, not a right.

OT: simplest way to display on-screen blinking colored indicator
by Ranjan Maitra 18 Apr '20

18 Apr '20

Dear friends, Sorry, this is OT but I thought that some of you might have suggestions. I want to have an on-screen indicator in the form of a icon or something that is blinking red if vpn is disconnected and steady green if vpn is up. Could also be extended to other features but right now let us go with this. The reason I need this is because the Cisco icon (that I need for VPN because of required third-party 2FA) is very tiny and almost impossible to see. It is time-consuming and distracting to constantly have to hover over the icon to see whether it says Connected and Disconnected. So, I am thinking of a small script that will check every second (say) if VPN is on or off and then display accordingly. The script part, I think I can write on my own. It is what th script will do/call that i am having trouble with. So any suggestions as to what I could do. Now, I am aware that I can perhaps get something like conky to be set up for this, but I was hoping to have something far simpler. But I do not quite know how to do the simple display part. My apologies again that this has nothing to do with Fedora, but I come as a proud and happy user of its 31 editions. Many thanks and best wishes, Ranjan

Unable to hibernate Fedora 31 using swap file
by Sreyan Chakravarty 18 Apr '20

18 Apr '20

I have Fedora 31 installed in VirtualBox, and I am trying to test out hibernation with a swap file, but no matter what I do I am unable to get Hibernation to work. I am using a 6GB swap file with the RAM allocated to the VM is 5GB, so the file should be sufficient for a successful hibernate. This is my /etc/fstab: /dev/mapper/vgfedora-fedora / ext4 defaults 1 1 UUID=070a13c2-7c99-4703-bb7a-e408245316c4 /boot ext4 defaults 1 2 /fedora.swap none swap 0 0 This is my grub.cfg: GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="rd.lvm.lv=vgfedora/fedora rhgb quiet resume=/dev/vgfedora/fedora resume_offset=587776" GRUB_DISABLE_RECOVERY="true" GRUB_ENABLE_BLSCFG=true I have followed the instructions from the Arch wiki: https://wiki.archlinux.org/index.php/Power_management/Suspend_and_hibernate… I am hibernating using the following command: sudo /usr/lib/systemd/systemd-sleep hibernate Weirdly, there are no errors in the log that I get with journalctl -b : https://pastebin.com/9cfnRx8V I have not added any hooks to the initramfs because if you see the tutorial it says that if you are using systemd then you don't need any additional hooks in the initramfs. Thus, I did not rebuild my initramfs. Do I have to do that ? Fedora uses systemd by default right ? I don't understand what I am doing wrong, I am only using LVM but no encryption. This is my lsblk -f output: NAME FSTYPE LABEL UUID FSAVAIL FSUSE% MOUNTPOINT sda ├─sda1 ext4 070a13c2-7c99-4703-bb7a-e408245316c4 739.3M 17% /boot └─sda2 LVM2_member m1OMiT-aeUG-9Fb1-pNSw-LmUn-rKJK-cHYASh └─vgfedora-fedora ext4 8cec892a-8da9-4ee2-95fe-bc2e0c4cd3aa 24G 34% / sr0 Let me know if there are any other logs I can include, I am unable to understand what is the root cause of the problem, there are no errors any where. Even SELinux is not complaining. Thanks. -- Regards, Sreyan Chakravarty
